Product Summary
The LT1180ACSW#TR is a dual RS232 driver/receiver pairs with integral charge pump to generate RS232 voltage levels from a single 5V supply. The LT1180ACSW#TR features 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 LT1180ACSW#TR to survive multiple ±10kV strikes, eliminating the need for costly TransZorbs on the RS232 line pins. The LT1180ACSW#TR is 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. The LT1180ACSW#TR applications are: (1)Portable Computers; (2)Battery Powered Systems; (3)Power Supply Generator; (4)Terminals; (5)Modems.
Parametrics
LT1180ACSW#TR absolute maximum ratings: (1)Supply Voltage (VCC): 6V; (2)V+: 13.2V; (3)V－: －13.2V; (4)Storage Temperature Range: － 65℃ to 150℃; (5)Lead Temperature (Soldering, 10 sec): 300℃.
Features
LT1180ACSW#TR features: (1) CMOS Comparable Low Power: 40mW; (2) Operates from a Single 5V Supply; (3) Rugged Bipolar Design; (4) Outputs Assume a High Impedance State When Off or Powered Down; (5) Meets All RS232 Specifications; (6) Available With or Without Shutdown; (7) Absolutely No Latch up; (8) Available in SO Package.
