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 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 in-

put 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.
