LT1332  
Wide Supply Range  
Low Power RS232 Transceiver with  
12V VPP Output for Flash Memory  
DESCRIPTION  
OBSOLETE:  
Contact Linear Technology for Potential Replacement  
FOR INFORMATION PURPOSES ONLY  
FEATURES  
n
Generates Full RS232 Signal Levels from 3V Supply  
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.

ESD Protection Over ±±10k

TheLT1332/LT1109Acombinationshownbelowgenerates  
fully compliant RS232 signal levels from as little as 2V of  
inputsupply. Theswitchercandelivergreaterthan100mA

Advanced driver output stages operate up to 120k baud  
while driving heavy capacitive loads. New ESD structures

eliminating costly transient suppressors.  
Available in SO and SSOP Packages  
APPLICATIONS  
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.
