The AT202E, AT232E and AT233E devices are a family of line driver and receiver pairs that meets the specifications of RS-232 and V.28 serial protocols. The devices are pin-to-pin compatible with Analogtek’s AT232A and AT233A devices as well as popular industry standard pinouts. The ESD tolerancehasbeenimprovedonthesedevicestoover±15kV for Human Body Model. This series offers a 120kbps data rate under load, small ceramic type 0.1µF charge pump capacitors and overall ruggedness for commercial applications. Features include Analogtek’s BiCMOS design which allows low power operation without sacrificing performance. The series is available in lead free packages and includes commercial and industrial temperatureranges.
