DESCRIPTION
The L293B and L293E are quad push-pull drivers
capableof delivering output currents to 1A per chan-
nel. Each channel is controlledby 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 L293Band 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.
