LT1130A/LT1140A Series Advanced Low Power 5V RS232 Drivers/Receivers with Small Capacitors DESCRIPTIO FEATURES n ESD Protection over 10kV The LT 1130A/LT1140A series of RS232 drivers/receiv- ( 15kV IEC-1000-4-2 for LT1133A, LT1137A ers features special bipolar construction techniques which and LT1141A) protect the drivers and receivers beyond the fault condi- n Uses Small Capacitors: 0.1m F, 0.2m F tions stipulated for RS232. Driver outputs and receiver n 1m A Supply Current in SHUTDOWN inputs can be shorted to 30V without damaging the n 120kBaud Operation for R = 3k, C = 2500pF device or the power supply generator. In addition, the L L n 250kBaud Operation for R = 3k, C = 1000pF RS232 I/O pins are resilient to multiple 10kV ESD strikes. L L n CMOS Comparable Low Power An advanced driver output stage operates up to 250kbaud n Easy PC Layout: Flowthrough Architecture while driving heavy capacitive loads. Supply current is n Rugged Bipolar Design: Absolutely No Latchup typically 12mA, competitive with CMOS devices. n Outputs Assume a High Impedance State When Off Several members of the series include flexible operating or Powered Down mode controls. The DRIVER DISABLE pin disables the n Improved Protection: RS232 I/O Lines Can Be Forced drivers and the charge pump, the ON/OFF pin shuts down to 30V Without Damage all circuitry.
