Integrated Circuit
Stepper Motor Driver
Description:
The NTE7082 is a bipolar integrated circuit in a 16–Lead DIP type package intended for driving a four–
phase two–state motor. The circuit consists of a bidirectional four–state counter and a code converter
to drive the four outputs in the sequence required for driving a stepping motor.
