DESCRIPTION
The L293B and L293E are quad push-pull drivers
capableofdeliveringoutputcurrentsto 1Aperchan-
nel.Eachchannelis controlledby a TTL-compatible
logic input and each pair of drivers (a full bridge) is
equippedwith an inhibit input whichturns off all four
transistors. A separatesupply input is provided for
the logic so that it may be run off a lower voltage to
reducedissipation.
Additionally, the L293E has external connection of
sensing resistors, for switchmode control.
TheL293BandL293Earepackagein16 and20-pin
plastic DIPs respectively ; both use the four center
pins to conduct heat to the printed circuit board.
