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

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.
