DESCRIPTION

The L293B and L293E are quad push-pull drivers

capableof deliveringoutputcurrentsto 1Aperchan-

nel. Each channelis controlledby a TTL-compatible

logic input and each pair of drivers (a full bridge) is

equippedwith 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.
