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.
Each circuit has CMOS compatible inputs with thresholds
that track as a function of V
CC
(approximately
(/2
V
CC
). The
inputs are PNPs providing the high impedance necessary
for interfacing with CMOS.
Outputs have high voltage capability, minimum breakdown
voltage is 56V at 250
m
A.
The outputs are Darlington connected transistors. This al-
lows high current operation (300 mA max) at low internal
V
CC
current levels since base drive for the output transistor
is obtained from the load in proportion to the required load-
ing conditions. This is essential in order to minimize loading
on the CMOS logic supply.
Typical V
CC
e
5V power is 28 mW with both outputs ON.
V
CC
operating range is 4.5V to 15V.
The circuit also features output transistor protection if the
V
CC
supply is lost by forcing the output into the high impe-
dance OFF state with the same breakdown levels as when
V
CC
was applied.
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.
The DS1631 series is also TTL compatible at V
CC
e
5V.
