FEATURES
s DESCRIPTIO s s s s s s s s s s s ESD Protection over ±10kV (±15kV IEC-1000-4-2 for LT1133A, LT1137A and LT1141A) Uses Small Capacitors: 0.1µF, 0.2µF 1µA Supply Current in SHUTDOWN 120kBaud Operation for RL = 3k, CL = 2500pF 250kBaud Operation for RL = 3k, CL = 1000pF CMOS Comparable Low Power Easy PC Layout: Flowthrough Architecture Rugged Bipolar Design: Absolutely No Latchup Outputs Assume a High Impedance State When Off or Powered Down Improved Protection: RS232 I/O Lines Can Be Forced to ± 30V Without Damage Output Overvoltage Does Not Force Current Back into Supplies Available in SO and SSOP Packages The LT ®1130A/LT1140A series of RS232 drivers/receivers features special bipolar construction techniques which protect the drivers and receivers beyond the fault conditions stipulated for RS232. Driver outputs and receiver inputs can be shorted to ± 30V without damaging the device or the power supply generator. In addition, the RS232 I/O pins are resilient to multiple ±10kV ESD strikes.
