The ADM3310E is a three-driver/five-receiver serial port transceiver, which meets EIA-232 standards while operating from a single power supply as low as +2.7V. It is similar to the ADM3311E but with two of the Receivers remain Active during Shutdown. It features an on-board, charge pump dc-to-dc converter, which eliminates the need for dual power supplies.This dc-to-dc converter also contains a voltage tripler and voltage inverter for internally generating positive and negative supplies from the power supply. It operates in Green Idle Mode, where the charge pump oscillator is gated on and off to maintain output voltage to +/-6 V, regardless of the load conditions. Another key feature is its ESD protection: up to +/−15kV on all I/O lines. The ADM3310E is available in a 28-pin TSSOP package as well as a space-saving 5×5mm 32-pin LFCSP package.APPLICATIONS Mobile phone handsets/data cables Laptop and notebook computers Printers Peripherals Modems PDAs/Hand-Held Devices/Palmtop Computers

The ADM560 / ADM561 are four driver/five receiver interface devices designed to meet the EIA-232 standard while operating with a single +3.3 V power supply. The devices feature an on-board dc-to-dc converter, eliminating the need for dual ±5 V power supplies. This dc-dc converter contains a voltage doubler and voltage inverter which internally generates ±6.6 V from the input +3.3 V power supply.The ADM560 and ADM561 consume only 5 mW making them ideally suited for battery and other power-sensitive applications.

In this device all receivers are disabled in shutdown.The ADM560 / ADM561 is fabricated using CMOS technology for minimal power consumption. It features a high level of over-voltage protection and latch-up immunity. The receiver inputs can withstand up to ±25 V levels.

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)

The ADM101E is a single channel RS-232 driver and receiver inthe Analog Devices Craft Port series, designed to operate from asingle, 5 V supply. A highly efficient charge-pump voltage invertergenerates an on-chip –5 V supply, which eliminates the needfor a negative power supply for the driver and permits RS-232compatible output levels to be developed using charge pumpcapacitors as small as 0.1 μF.A shutdown input disables the charge pump and puts the deviceinto a low power shutdown mode, in which the current consumptionis typically less than 1 μA. The transmitter is disabledduring shutdown but the receiver remains functional. Craft Port is a trademark of Analog Devices, Inc.An epitaxial BiCMOS construction minimizes power consumptionto 3 mW and also guards against latch-up. Overvoltageprotection is provided allowing the receiver inputs to withstandcontinuous voltages in excess of ±30 V. In addition, all I-O pinshave ESD protection to levels greater than 15 kV.The ADM101E is available in a 10-lead μSOIC package, whichmakes it ideal for serial communications in small, portableapplications such as palmtop computers and mobile telephones,where a full, RS-232 serial interface is not required, but compactsize and low power drain are paramount.

Excessive power dissipation caused by bus contention or output shorting is prevented by short-circuit protection and thermal circuitry.Short-circuit protection circuits limit the maximum output current to ±250 mA during fault conditions. A thermal shutdown circuit senses if the die temperature rises above 150°C and forces the driver outputs into a high impedance state under this condition.The receiver of the ADM1491E contains a fail-safe feature that results in a logic high output state if the inputs are unconnected (floating).The ADM1491E features extremely fast and closely matched switching times. Minimal driver propagation delays permit transmission at data rates up to 16 Mbps while low skew minimizes EMI interference.The ADM1491E is fully specified over the commercial and industrial temperature ranges and is available in two packages: a narrow-body 14-lead SOIC and a 10-lead MSOP.APPLICATIONS RS-485/RS-422 interfaces Industrial field networks High data rate motor control Multipoint data transmission systems Single-ended to differential signal conversion
