L293D Description

The device is a four-channel monolithic integrated high voltage, high current

driver designed to handle normal DTL or TTL logic levels and drive inductive 

loads (such as relays, solenoids, DC and stepping motors) and switching power

transistors. Each pair of channels has an enable input to facilitate use as two

bridges. The logic has a separate supply input that allows it to operate at a

lower voltage, and internal clamp diodes are included. This device can be used 

in switching applications with frequencies of up to 5 kHz.

L293D Pinout

The L-293D has sixteen (16) pins, each with a unique function.

The table below lists all sixteen pins, along with their serial numbers.
