Description
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 noninverting circuits which can be connected by metal mask
programation 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.

Stresses above these listed maximum ratings may cause
permanent damage to the device. Exposure to conditions
beyond specified electrical characteristics may affect
device reliability or cause malfunction.
This device contains circuitry to protect the terminals
against damage due to high static voltages or electrical
fields. However, it is advised that normal precautions be
taken to avoid application of any voltage higher than
minimum rated voltages to this circuit.
