H-Bridge Motor Driver 1A

The SN754410 is a quad half H-bridge motor driver IC capable of driving DC motors, stepper motors, and other inductive loads. It accepts TTL 5V logic inputs and can drive motors from 4.5V to 36V at up to 1A continuous output current per channel.

A pin-compatible replacement for the popular L293D, making it a straightforward drop-in upgrade for existing designs. Two half H-bridges can be combined for full bidirectional control of a single motor, or all four can be used independently.
