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
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
mA
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
