  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.
