DS1631/DS3631/DS1632/DS3632/DS1633/DS3633/
DS1634/DS3634 CMOS Dual Peripheral Drivers
General Description
The DS1631 series of dual peripheral drivers was designed
to be a universal set of interface components for CMOS
circuits.

Pin-outs are the same as the respective logic functions
found in the following popular series of circuits: DS75451,
DS75461. This feature allows direct conversion of present
systems to the MM74C CMOS family and DS1631 series
circuits with great power savings.
Each circuit has CMOS compatible inputs with thresholds
that track as a function of V (approximately (/2 V ). The

inputs are PNPs providing the high impedance necessary
for interfacing with CMOS.
