The SAA1042 drives a two–phase stepper motor in the bipolar mode. The

device contains three input stages, a logic section and two output stages.

The IC is contained in a 16 pin dual–in–line heat tab plastic package for

improved heatsinking capability. The center four ground pins are connected

to the copper alloy heat tab and improve thermal conduction from the die to

the circuit board.
