  • The L293B and L293E are quad push-pull drivers capable of delivering output currents to 1A per channel. Each channel is controlled by a TTL-compatible logic input and each pair of drivers (a full bridge) is equipped with an inhibit input which turns off all four transistors. A separate supply input is provided for the logic so that it may be run off a lower voltage to reduce dissipation.

    Additionally, the L293E has external connection of sensing resistors, for switchmode control.
    The L293B and L293E are package in 16 and 20-pin plastic DIPs respectively ; both use the four center pins to conduct heat to the printed circuit board.

    Key Features

    • OVERTEMPERATURE PROTECTION
    • OUTPUT CURRENT 1A PER CHANNEL
    • INHIBIT FACILITY
    • PEAK OUTPUT CURRENT 2A PER CHANNEL (non repetitive)
    • SEPARATE LOGIC SUPPLY
    • HIGH NOISE IMMUNITY
