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.
