SP202E,SP232E, SP233E, SP310E and SP312E High Performance RS-232 Line Drivers/Receivers FEATURES Operates from a Single +5V Power Supply Meets all RS-232D and ITU V.28 Specifications Operates with 0. F to 0 F Ceramic Capacitors No External Capacitors required (SP233E) Low Power Shutdown (SP30E, SP3 2E) High Data Rate - 20kbps under load Low power CMOS Operation Lead Free packaging available Improved ESD Specifications: +/- 5kV Human Body Model DESCRIPTION The SP202E, SP232E, SP233E, SP3 0E and SP3 2E devices are a family of line driver and re - ceiver 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, SP3 0A and SP32A devices as well as popular industry standard pinouts. The ESD tolerance has been improved on these devices to over +/- 5kV for Human Body Model. This series offer a 20kbps data rate under load, small ceramic type 0. F 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.
