Description

The ADM3202/ADM3222/ADM1385 transceivers are high speed, 2-channel RS-232/V.28 interface devices which operate from a single +3.3 V power supply. Low power consumption and a shutdown facility ADM3202/ADM3222/ADM1385 ) makes them ideal for battery powered portable instruments. The ADM3202/ADM3222/ADM1385 conforms to the EIA- 232E and CCITT V.28 specifications and operates at data rates up to 460 kbps. Four external 0.1 F charge pump capacitors are used for the voltage doubler/inverter permitting operation from a single +3.3 V supply. It contains additional enable and shutdown circuitry.
The EN input may 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 A. The receivers remain enabled during shutdown unless disabled using EN. The ADM3202/ADM3222/ADM1385  contains a driver disable mode and a complete shutdown mode. The product is available in a 16-lead DIP, narrow and wide SOIC as well as a space saving 20-lead TSSOP package. The ADM3222 is available in 18-lead DIP, SO and in 20-lead SSOP and TSSOP. The product  is available in a 20-lead SSOP package, which is pin compatible with the LTC1385 CG.
