LT1280A/LT1281A Low Power 5V RS232 Dual Driver/Receiver with 0.
1µF Capacitors DESCRIPTIO The LT ®1280A/LT1281A are dual RS232 driver/receiver pairs with integral charge pump to generate RS232 voltage levels from a single 5V supply.
These circuits feature rugged bipolar design to provide operating fault tolerance and ESD protection unmatched by competing CMOS designs.
Using only 0.
1µF external capacitors, these circuits consume only 40mW of power, and can operate to 120kbaud even while driving heavy capacitive loads.
New ESD structures on the chip allow the LT1280A/LT1281A to survive multiple ±10kV strikes, eliminating the need for costly TransZorbs® on the RS232 line pins.
