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. External high-speed output clamp diodes should be used for inductive transient suppression. When the enable input is low, those drivers are disabled, and their outputs are off and in a high-impedance state. With the proper data inputs, each pair of drivers form a full-H (or bridge) reversible drive suitable for solenoid or motor applications.

The L293D is designed for operation from 0°C to 70°C. 3 1 1, 2EN The L293D is a quadruple high-current half-H driver designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V. It is 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. 3Y 3A 3, 4EN logic symbol† 1A description VCC1 4A 4Y HEAT SINK AND GROUND INPUTS‡ A EN OUTPUT Y H L X H H L H L Z H = high-level, L = low level, X = irrelevant, Z = high-impedance (off) ‡ In the thermal shutdown mode, the output is in the high-impedance state regardless of the input levels.
