SP231A/232A/233A/310A/312A

Enhanced RS-232 Line Drivers/Receivers

sOperates from Single 5V Power Supply

sMeets All RS-232D and V.28

Specifications

sMultiple Drivers and Receivers

sSmall Charge Pump Capacitors –

0.1µF

sOperates with 0.1µF and 100µF

Capacitors

sHigh Data Rate – 120kbps Under Load

sHigh Output Slew Rate –

10V/µs Under Load

sLow Power Shutdown ≤1µA

s3-State TTL/CMOS Receiver Outputs

s±30V Receiver Input Levels

sLow Power CMOS – 15mA Operation

DESCRIPTION…

The Sipex SP231A, SP232A and SP233A are enhanced versions of the Sipex SP231, SP232

and SP233 RS-232 line drivers/receivers. They are pin-for-pin replacements for these earlier

versions and will operate in their sockets. Performance enhancements include 10V/µs slew rate,

120k bits per second guaranteed transmission rate, and increased drive current for longer and

more flexible cable configurations. Ease of use enhancements include smaller, 0.1µF charge

pump capacitors, enhanced ESD protection, low power dissipation and overall ruggedized

construction for commercial environments. The series is available in plastic and ceramic DIP and

SOIC packages operating over the commercial, industrial and military temperature ranges.
