GENERAL DESCRIPTION

The ADM3202/ADM3222/ADM1385 transceivers are high

speed, 2-channel RS-232/V.28 interface devices that operate

from a single 3.3 V power supply. Low power consumption and

a shutdown facility (ADM3222/ADM1385) make them ideal for

battery-powered portable instruments.

The ADM3202/ADM3222/ADM1385 parts conform to the

EIA-232E and CCITT V.28 specifications and operate at data

rates up to 460 kbps.

Four external 0.1 µF charge pump capacitors are used for the

voltage doubler/inverter, permitting operation from a single

3.3 V supply.

The ADM3222 contains additional enable and shutdown

circuitry. The EN input can be used to three-state the receiver

outputs. The SD input is used to power down the charge pump

and transmitter outputs, reducing the quiescent current to less

than 0.5 µA. The receivers remain enabled during shutdown

unless disabled using EN.

The ADM1385 contains a driver disable mode and a complete

shutdown mode.

The ADM3202 is available in a 16-lead PDIP, SOIC_W, and

SOIC_N, as well as a space-saving 16-lead TSSOP. The ADM3222

is available in 18-lead PDIP and SOIC_W and in 20-lead SSOP

and TSSOP. The ADM1385 is available in a 20-lead SSOP,

which is pin-compatible with the LTC1385 CG
