... Advanced driver output stages operate up to 120k baud while driving heavy capacitive loads. New ESD structures on chip make the LT1332 resilient to multiple 10kV strikes, eliminating costly transient suppressors. A shutdown pin disables the transceiver except for one receiver which remains active for detecting incoming RS232 signals ...
