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, 0.1

µF 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.
