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.

Each output is a totem-pole drive circuit, with a complete 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.

L293, L293D QUADRUPLE HALF-H DRIVERS SLRS008C − SEPTEMBER 1986 − REVISED NOVEMBER 2004 description/ordering information (continued) On the L293, external high-speed output clamp diodes should be used for inductive transient suppression. A VCC1 terminal, separate from VCC2, is provided for the logic inputs to minimize device power dissipation. The L293and L293D are characterized for operation from 0°C to 70°C. block diagram 1 0 1 0 1 0 1 2 3 4 5 6 7 8 1 2 VCC1 1 0 1 0 1 0 16 15 14 13 12 11 10 9 4 3 M M M VCC2 NOTE: Output diodes are internal in L293D.
