功能描述
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. An advanced driver output stage operates up to 250kbaud while driving heavy capacitive loads. Supply current is typically 12mA, competitive with CMOS devices.Several members of the series include flexible operating mode controls. The DRIVER DISABLE pin disables the drivers and the charge pump, the ON/OFF pin shuts down all circuitry. While shut down, the drivers and receivers assume high impedance output states.
特点
  • 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
    • 应用
