CS8442 85mA Dual H-Bridge Odometer Driver with Buffered Speed Signal Output

The CS8442 is a stepper motor driver that implements an Hbridge design to drive two coils in an eight step sequence each revolution. Each H-bridge is capable of delivering 85mA to the load. The sequencer function insures that the odometer is monotonic and that cross-conduction of each H bridges does.
