L293D یک آی سی درایور باخروجی 4.5 ولت تا 36 ولت و با جریان 1.2آمپر می باشد. این قطعه برای راه اندازی رله ها ،استپر موتورها مناسب و دارای 16 پایه میباشد.
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.
