description/ordering information

The L293 and L293D are quadruple high-current

half-H drivers. The L293 is designed to provide

bidirectional drive currents of up to 1 A at voltages

from 4.5 V to 36 V. The L293D is designed to

provide bidirectional drive currents of up to

600-mA at voltages from 4.5 V to 36 V. Both

devices are designed to drive inductive loads such

as relays, solenoids, dc and bipolar stepping

motors, as well as other high-current/high-voltage

loads in positive-supply applications.

All inputs are TTL compatible. Each output is a

complete

totem-pole

drive

circuit,

with

a

Darlington

transistor

sink

and

a

pseudo-

Darlington source. Drivers are enabled in pairs, with drivers 1 and 2 enabled by 1,2EN and drivers 3 and 4

enabled by 3,4EN. When an enable input is high, the associated drivers are enabled, and their outputs are active

and in phase with their inputs. When the enable input is low, those drivers are disabled, and their outputs are

off and in the high-impedance state. With the proper data inputs, each pair of drivers forms a full-H (or bridge)

reversible drive suitable for solenoid or motor applications.
