description

The SN754410 is a quadruple high-current half-H

driver designed to provide bidirectional drive

currents up to 1 A at voltages from 4.5 V to 36 V.

The device 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.

All inputs are compatible with TTL-and low-level CMOS logic. Each output (Y) is a complete totem-pole driver

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 become active and in phase with their inputs. 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.

The SN754410 is designed for operation from – 40

°C to 85°C.
