DESCRIPTION
The L293D device is quadruple high-current half-H drivers. The L293D is designed to provide bidirectional drive currents of up to 600mA at voltages from 4.5V to 36V. Both devices ae designed to driver inductive loads such as relays, solenoids, DC and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications.
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 EN1/2 and drivers 3 and 4 enabled by EN3/4.
The L293D is characterized for operation from 0°C to 70°C.
