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.
