The ADG436 is a monolithic CMOS device comprising two independently selectable SPDT switches. It is designed on an LC2MOS process which provides low power dissipation yet gives high switching speed and low on resistance.Each switch conducts equally well in both directions when ON and has an input signal range which extends to the power supplies. In the OFF condition, signal levels up to the supplies are blocked. All switches exhibit break-before-make switching action for use in multiplexer applications. Inherent in the design is low charge injection for minimum transients when switching the digital inputs.

The ADG528A and ADG529A are CMOS monolithic analogmultiplexers with eight channels and four dual channels, respectively.On-chip latches facilitate microprocessor interfacing. TheADG528A switches one of eight inputs to a common output,depending on the state of three binary addresses and an enableinput. The ADG529A switches one of four differential inputs toa common differential output, depending on the state of twobinary addresses and an enable input. Both devices have TTLand 5 V CMOS logic-compatible digital inputs.The ADG528A and ADG529A are designed on an enhancedLC2MOS process, which gives an increased signal capability ofVSS to VDD and enables operation over a wide range of supplyvoltages. The devices can comfortably operate anywhere in the10.8 V to 16.5 V single- or dual-supply range. Thesemultiplex-ers also feature high switching and low RON.The ADG529A is no longer available.Product Highlights Single-/dual-supply specifications with a wide tolerance. The devices are specified in the 10.8 V to 16.5 V range for both single- and dual-supplies. Easily Interfaced The ADG528A and ADG529A can be easily interfaced with microprocessors. The WR signal latches the state of the address control lines and the enable line. The RS signal clears both the address and enable data in the latches resulting in no output (all switches off). RS can be tied to the microprocessor reset pin. Extended Signal Range The enhanced LC2MOS processing results in a high breakdown and an increased analog signal range of VSS to VDD. Break-Before-Make Switching Switches are guaranteed break-before-make so that input signals are protected against momentary shorting. Low Leakage Leakage currents in the range of 20 pA make these multiplexers suitable for high precision circuits.

The ADG787 is a low voltage, CMOS device that contains two independently selectable, single-pole, double-throw (SPDT) switches. It is designed as a general analog/digital switch and can also be used for routing USB 1.1 signals.This device offers low on resistance of typically 2.5 Ω, making the part an attractive solution for applications that require low distortion through the switch.The ADG787 comes in a tiny 3 × 4 bump, 1.50 mm × 2.00 mm WLCSP, a tiny 10-lead LFCSP, and a 10-lead MSOP. These packages make the ADG787 the ideal solution for space-constrained applications. Each switch conducts equally well in both directions when on and has an input signal range that extends to the supplies.

The ADM2xx family of line drivers/receivers is intended for all EIA-232-E and V.28 communications interfaces, especially in applications where ±12 V is not available. The ADM205, ADM211 and ADM213 feature a low power shutdown mode which reduces power dissipation to less than 5 µW making them ideally suited for battery powered equipment. The ADM205 does not require any external components and is particularly useful in applications where printed circuit board space critical. The ADM213 has an active-low shutdown and an active-high receiver enable control. Two receivers of the ADM213 remain active during shutdown. This feature is useful for ring indicator monitoring.All members of the ADM2xx family, except the ADM209, include two internal charge pump voltage converters which allow operation from a single +5 V supply. These converters convert the +5 V input power to the ±10 V required for RS-232 output levels. The ADM209 is designed to operate from +5 V and +12 V supplies. An internal +12 V to −12 V charge pump voltage converter generates the −12 V supply.

The ADM2xxE is a family of robust RS-232 and V.28 interface devices which operates from a single +5 V power supply. These products are suitable for operation in harsh electrical environments and are compliant with the EU directive on EMC (89/336/ EEC). Both the level of emissions and immunity are in compliance. EM immunity includes ESD protection in excess of ±15 kV on all I-O lines (1000-4-2), Fast Transient Burst protection (1000-4-4) and Radiated Immunity (1000-4-3). EM emissions include radiated and conducted emissions as required by Information Technology Equipment EN55022, CISPR22.All devices fully conform to the EIA-232E and CCITT V.28 specifications and operate at data rates up to 230 kbps. Shutdown and Enable control pins are provided on some of the products. The shutdown function on the ADM211E disables the charge pump and all transmitters and receivers. On the ADM213E the charge pump, all transmitters, and three of the five receivers are disabled. The remaining two receivers remain active thereby allowing monitoring of peripheral devices. This feature allows the device to be shut down until a peripheral device begins communication. The active receivers can alert the processor which can then take the ADM213E out of the shutdown mode. Operating from a single +5 V supply, four external 0.1 µF capacitors are required. The ADM206E is available in a 24-pin SO package. The ADM207E and ADM208E are available in 24-pin DIP, SO, SSOP and TSSOP packages. The ADM211E and ADM213E are available in 28-pin SO, SSOP and TSSOP packages.

The ADM485 is a differential line transceiver suitable for high speed bidirectional data communication on multipoint bus transmission lines. It is designed for balanced data transmission and complies with both EIA Standards RS-485 and RS-422. The part contains a differential line driver and a differential line receiver. Both the driver and the receiver may be enabled independently. When disabled, the outputs are tristated.The ADM485 operates from a single +5 V power supply. Excessive power dissipation caused by bus contention or by output shorting is prevented by a thermal shutdown circuit. This feature forces the driver output into a high impedance state if during fault conditions a significant temperature increase is detected in the internal driver circuitry.Up to 32 transceivers may be connected simultaneously on a bus, but only one driver should be enabled at any time. It is important, therefore, that the remaining disabled drivers do not load the bus. To ensure this, the ADM485 driver features high output impedance when disabled and also when powered down. This minimizes the loading effect when the transceiver is not being utilized. The high impedance driver output is maintained over the entire common-mode voltage range form -7V to +12 V.The receiver contains a fail safe feature which results in a logic high output state if the inputs are unconnected (floating).The ADM485 is fabricated on BiCMOS, an advanced mixed technology process combining low power CMOS with fast switching bipolar technology. All inputs and outputs contain protection against EDS; all diver outputs feature high source and sink current capability. An epitaxial layer is used to guard against latch-up.The ADM485 features extremely fast switching speeds. Minimal driver propagation delays permit transmission at data rates up to 5 Mbits/s while low skew minimizes EMI interference. The part is fully specified over the commercial and industrial temperature range and is available in an 8-pin DIL/SOIC packages.
