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.

†
This symbol is in accordance with ANSI/IEEE Std 91-1984  
and IEC Publication 617-12.  
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. 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.
