DESCRIPTION

FEATURES

SP202E,SP232E, SP233E, SP310E and SP312E

High Performance RS-232 Line Drivers/Receivers

• Operates from a Single +5V Power Supply

• Meets all RS-232D and ITU V.28 Specications

• Operates with 0.1μF to 10μF Ceramic Capacitors

• No External Capacitors required (SP233E)

• Low Power Shutdown (SP310E, SP312E)

• High Data Rate - 120kbps under load

• Low power CMOS Operation

• Lead Free packaging available

• Improved ESD Specications:

+/-15kV Human Body Model

The SP202E, SP232E, SP233E, SP310E and SP312E devices are a family of line driver and re-

ceiver pairs that meets the specications 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 sacricing performance. The series is

available in lead free packages with commercial and industrial temperature ranges.
