SP3203E RS232 收发器 带 1.8V 逻辑接口, 3发/2收
The SP202E, SP232E, SP233E, SP310E and SP3203E 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 Exar's SP232A, SP233A, SP310A and SP312A devices as well as popular industry standard pinouts. The ESD tolerance has been improved on these devices to over +/-15kV for Human Body Model. This series offer a 120kbps data rate under load, small ceramic type 0.1µF charge pump capacitors and overall ruggedness for comercial applications. Features include Exar's BiCMOS design which allowing low power operation without sacrificing performance. The series is available in lead free packages with commercial and industrial temperature ranges.
