... Low 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/ s slew rate, 120k bits per second guaranteed transmission rate, and increased drive current for longer and more flexible cable configurations ...
