The l293 is designed to providebidirectional drive currents of up to 1 A at voltagesfrom V to 36 V.

2 The L293D is designed toprovide bidirectional drive currents of up to600-mA at voltages from V to 36 V. Bothdevices are designed to drive inductive loads suchas relays, solenoids, dc and bipolar steppingmotors, as well as other high-current/high-voltageloads in positive-supply inputs are TTL compatible. Each output is a complete totem-pole drive circuit, with a Darlington transistorsink and a pseudo-Darlington source. DRIVERS are enabled in pairs, with DRIVERS 1 and 2 enabled by 1,2EN anddrivers 3 and 4 enabled by 3,4EN. When an enable input is high, the associated DRIVERS are enabled and theiroutputs are active and in phase with their inputs.

3 When the enable input is low, those DRIVERS are disabled andtheir outputs are off and in the high-impedance state. With the proper data inputs, each pair of DRIVERS formsa full-H (or bridge) reversible drive suitable for solenoid or motor the l293 , external high-speed output clamp diodes should be used for inductive transient VCC1 terminal, separate from VCC2, is provided for the logic inputs to minimize device power L293and L293D are characterized for operation from 0 C to 70 2002, Texas Instruments IncorporatedPRODUCTION DATA information is current as of publication conform to specifications per the terms of Texas Instrumentsstandard warranty.
