Overview

The SN754410NE is a quadruple high-current half-H driver designed to provide bidirectional drive current of up to 1 A at voltages from 4.5 V to 36 V. It is a popular pin-to-pin replacement for the L293D, offering higher output current capability and integrated thermal shutdown for driving inductive loads like motors and solenoids.

Why Choose This Part

The device features internal ESD protection and input hysteresis for improved noise immunity in electrically noisy motor environments. Its separate logic supply input allows for seamless interfacing with 5V microcontrollers while driving loads at much higher voltages up to 36V.

Applications

Bipolar Stepper Motor Control
Driving the two coils of a bipolar stepper motor in full-step or half-step modes using the four integrated half-H drivers.
Dual DC Motor Drive
Providing independent bidirectional control for two brushed DC motors with up to 1 A continuous current per channel.
Solenoid and Relay Switching
High-side or low-side switching of inductive loads in industrial and hobbyist automation projects.
High-Current Logic Buffering
Interfacing low-power TTL or CMOS logic signals to high-voltage, high-current peripherals.

Getting Started

For prototyping, the PDIP package allows direct insertion into breadboards or 16-pin IC sockets. Ensure a 0.1 uF decoupling capacitor is placed close to both the VCC1 (logic) and VCC2 (load) pins, and utilize the four center ground pins as a heat sink by connecting them to large copper planes.
