L293, L293D

SLRS008D – SEPTEMBER 1986 – REVISED JANUARY 2016

L293x Quadruple Half-H Drivers

1 Features

3 Description

The L293 and L293D devices are quadruple high-

1

•

Wide Supply-Voltage Range: 4.5 V to 36 V

current half-H drivers. The L293 is designed to

Internal ESD Protection

voltages from 4.5 V to 36 V. The L293D is designed

to provide bidirectional drive currents of up to 600-mA

•

High-Noise-Immunity Inputs

at voltages from 4.5 V to 36 V. Both devices are

loads

in

positive-

L293D)

supply applications.

•

Output Clamp Diodes for Inductive Transient

Each output is a complete totem-pole drive circuit,
