The EM5060 (previously named H5060) is a low power integrated circuit in HCMOS Silicon Gate Technology designed to drive bipolar or unipolar stepping motors. This device contains four identical and independent non-inverting circuits which can be connected by metal mask programming so as to obtain two identical non-inverting circuits with a lower resistance output. Each buffer is driven by a special cell which dephases the P and N transistor signal input, for a minimization of the transversal transition current. A tristate input HIZ, with internal pulldown resistor provides the high impedance state of the four outputs.
