1 / 19 page L293, L293D QUADRUPLE HALFH DRIVERS SLRS008C − SEPTEMBER 1986 − REVISED NOVEMBER 2004 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Featuring Unitrode L293 and L293D Products Now From Texas Instruments D Wide Supply-Voltage Range: 4.5 V to 36 V D Separate Input-Logic Supply D Internal ESD Protection D Thermal Shutdown D High-Noise-Immunity Inputs D Functionally Similar to SGS L293 and SGS L293D D Output Current 1 A Per Channel (600 mA for L293D) D Peak Output Current 2 A Per Channel (1.2 A for L293D) D Output Clamp Diodes for Inductive Transient Suppression (L293D) 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.
