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.
A separate supply voltage (V
Supply voltage V
is used for the output circuits.
CC2
) is provided for the logic input circuits to minimize device power dissipation.

The SN754410 is designed for operation from –40°C to 85°C.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.

†
Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values are with respect to network GND.
2. For operation above 25°C free-air temperature, derate linearly at the rate of 16.6 mW/°C. To avoid exceeding the design maximum
virtual junction temperature, these ratings should not be exceeded. Due to variations in individual device electrical characteristics
and thermal resistance, the built-in thermal overload protection can be activated at power levels slightly above or below the rated
dissipation.
