The L293 and L293D devices 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
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.
The L293 and L293D are characterized for operation from 0°C to 70°C.
