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. All products are backward compatible with earlier ADM2xx products facilitating easy upgrading of older designs.

The ADM222, ADM232A, ADM242 are a family of high-speedRS-232 line drivers/receivers offering transmission rates up to200 kB/s. Operating from a single 5 V power supply, a highlyefficient on-chip charge pump using small (0.1 µF) externalcapacitors allows RS-232 bipolar levels to be developed. TwoRS-232 drivers and two RS-232 receivers are provided oneach device.The devices are fabricated on BiCMOS, an advanced mixedtechnology process that combines low power CMOS with highspeedbipolar circuitry. This allows for transmission rates up to200 kB/s, yet minimizes the quiescent power supply current tounder 5 mA.The ADM232A is a pin-compatible, high-speed upgrade for theAD232 and for the ADM232L. It is available in 16-lead DIPand in both narrow and wide surface-mount (SOIC) packages.The ADM222 contains an additional shutdown (SHDN) functionthat may be used to disable the device, thereby reducing thesupply current to 0.1 µA. During shutdown, all transmit/receivefunctions are disabled. The ADM222 is available in 18-leadDIP and in a wide surface-mount (SOIC) package.The ADM242 combines both shutdown (SHDN) and enable(EN) functions. The shutdown function reduces the supplycurrent to 0.1 mA. During shutdown, the transmitters are disabledbut the receivers continue to operate normally. Theenable function allows the receiver outputs to be disabledthereby facilitating sharing a common bus. The ADM242 isavailable in 18-lead DIP and in a wide surface-mount (SOIC)package.Applications Computers Peripherals Modems Printers Instruments

The AD7306 line driver/receiver is a 5 V monolithic product which provides an interface between TTL signal levels and dual standard EIA RS-232/RS-422 signal levels. The part contains two RS-232 drivers, one RS-422 driver, one RS-232 receiver, and one receiver path which can be configured either as RS-232 or as RS-422.An internal charge pump voltage converter facilitates operation from a single +5 V power supply. The internal charge pump generates ±10 V levels allowing RS-232 output levels to be developed without the need for external bipolar power supplies.A highly efficient charge pump design allows operation using non polarized, miniature 0.1 mF capacitors. This gives a considerable saving in printed circuit board space over conventional products which can use up to 10 mF capacitors. The charge pump output voltages may also be used to power external circuitry which requires dual supplies.The RS-232 channels are suitable for communications rates up to 100 kHz and the RS-422 channels are suitable for high speed communications up to 5 MHz. The RS-422 transmitter complementaryoutputs are closely matched and feature low timing skew between the complementary outputs. This is often an essential requirement to meet tight system timing specifications.All inputs feature ESD protection, all driver outputs feature high source and sink current capability and are internally protected against short circuits on the outputs. An epitaxial layer is used to guard against latch-up.The part is available in a 24-lead SOIC and 24-pin plastic DIP package.Applications DTE-DCE Interface Packet Switching Local Area Networks Data Concentration Data Multiplexers Integrated Services Digital Network (ISDN)
