DS1634DS3634 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

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

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

The circuit also features output transistor protection if the

dance OFF state with the same breakdown levels as when

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
