DWP PACKAGE (TOP VIEW) 1,2EN 1A 1Y NC NC NC 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. 1 HEAT SINK AND GROUND 1 28 2 27 3 26 4 25 5 24 6 23 7 22 8 21 9 20 NC NC 2Y 2A 10 19 11 18 12 17 13 16 VCC2 14 15 VCC1 4A 4Y NC NC NC HEAT SINK AND GROUND NC NC 3Y 3A 3,4EN All inputs are TTL compatible. Each output is a complete totem-pole drive circuit, with a Darlington transistor sink and a pseudoDarlington 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.
