DESCRIPTION The L293B and L293E are quad push-pull drivers capable of delivering output currents to 1A per channel. Each channel is controlled by a TTLcompatible 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 PIN CONNECTION (Top view)

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