ESCRIPTIO
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 gener-
ates 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 LT1332 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.
