Description

The LT1332 is a 3-driver/5-receiver RS232 transceiver,designed to be used in conjunction with a switching regulator. The LT1332 shares the regulator's positive output, while charge is capacitively pumped from the regulator's switch pin to the negative supply. Schottky rectifiers built into the LT1332 simplify the charge pump design.

The LT1332/LT1109A combination shown below generates fully compliant RS232 signal levels from as little as 2V of input supply. The switcher can deliver greater than 100mA of output current, making the it an excellent choice for mouse driver circuits.

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. When shut down, the disabled drivers and receivers assume high impedance output states.
