Description

The LT®1180A/ LT1181ACN 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 0.1mF external capacitors, these circuits consume only 40mW of power, and can operate to 120k baud even while driving heavy capacitive loads. New ESD structures on the chip allow the LT1180A/LT1181A to survive multiple ±10kV strikes, eliminating the need for costly TransZorbs® on the RS232 line pins. The LT1180A/ LT1181A are fully compliant with EIA RS232 standards. Driver outputs are protected from overload, and can be shorted to ground or up to ±30V without damage. During shutdown or power-off conditions, driver and receiver outputs are in a high impedance state, allowing line sharing. LT1181ACN Features • ESD Protection over ±10kV• Uses Small Capacitors: 0.1mF• 120kBaud Operation for RL = 3k, CL = 2500pF• 250kBaud Operation for RL = 3k, CL = 1000pF• Outputs Withstand ±30V Without Damage• CMOS Comparable Low Power: 40mW• Operates from a Single 5V Supply• Rugged Bipolar Design• Outputs Assume a High Impedance State When Off or Powered Down• Meets All RS232 Specifications• Available With or Without Shutdown• Absolutely No Latch-up• Available in SO Package LT1181ACN Applications • Portable Computers• Battery-Powered Systems• Power Supply Generator• Terminals• Modems
