SN754410 motor driver

Using SN754410 quadruple high-current half-H driver designed to provide bidirectional drive
currents up to 1A at voltages from 4.5 V to 36 V can be designed a very simple high efficiency motor controller circuit.
The SN754410 device is designed to drive inductive loads such as relays, solenoids, dc and bipolar stepping motors.

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.

As you can see in the circuit diagram this motor driver electronic project require few external components and separate supply voltage (VCC1 that is used for the logic input circuits to minimize device power dissipation.
Supply voltage VCC2 is used for the output circuits.
