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
constructionforcommercialenvironments. TheseriesisavailableinplasticandceramicDIPand
