  • Description

    The LT1140CN belongs to the LT1130A/LT1140A series of RS232 drivers/receivers that feature special bipolar construction techniques. These techniques protect the drivers and receivers from various fault conditions beyond the requirements stipulated for RS232. The advanced driver output stage operates up to 250kbaud while driving heavy capacitive loads. The supply current is typically 12mA, comparable with CMOS devices. Several members of the series include flexible operating mode controls.

    Specifications and features

    The LT1140CN has several features including:

    • 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
    • Available in SO and SSOP Packages
