Quadruple Half-H Driver, SN754410NE, Texas Instruments

The SN754410NE is a high-current half-H driver that provides bidirectional drive currents up to 1 A at voltages from 4.5 V to 36 V. It is designed to drive inductive loads such as relays, solenoids, DC and bipolar stepping motors, and 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: drivers 1 and 2 are enabled by 1,2EN, and drivers 3 and 4 are enabled by 3,4EN. When an enable input is high, the associated drivers are active and follow their inputs; when the enable input is low, the drivers are disabled and their outputs enter a high-impedance state. With the proper data inputs, each pair of drivers forms a full-H (bridge) reversible drive suitable for solenoid or motor control.
