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.μF to 0μF Ceramic Capacitors
• No External Capacitors required (SP233E)
• Low Power Shutdown (SP30E, SP32E)
• High Data Rate - 20kbps under load
• Low power CMOS Operation
• Lead Free packaging available
• Improved ESD Specifications:
+/-5kV Human Body Model
The SP202E, SP232E, SP233E, SP30E and SP32E 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, SP30A 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.μF
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.
