The L293 and/or L293D are types of a Quad Half H-Bridge Driver IC. The difference between those two is only that theL293 for Bidirectional DC Motor ControlL293 can provide bidirectional drive current up to 1 A, and the L293D is up to 600-mA in the same voltages from 4.5 V to 36 V (wide supply-voltage range). Below we provide you aboutL293D datasheet with application devicefor other purpose,mounting instructions of the device, and schematics diagrams of inputs and outputs.

The L293D Datasheetfeatures such Separate Input-Logic Supply, Internal ESD Protection, High-Noise-Immunity Inputs, Similar function to SGS L293 and SGS L293D, Thermal Shutdown and etc. It is recommended to operate in the parameters: supply voltage= 4.5-7 V for Vcc1 and Vcc1-36 V for Vcc2, VIH=2.3-7 V, VIL= -0.3 – 1.5 V, and Up to 70 C for its operating free-air temperature.

All inputs are TTL compatible. Each output is a complete totem-pole drive circuit, with a Darlington transistor sink and a pseudo- Darlington source. 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.The L293Dis converting low voltage, low current logic signals to high voltage, high current signals which is mainly used to directly drive a motor application, relay, dc, and solenoid.
