DS3634 CMOS Dual Peripheral Drivers

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 VCC (approximately VCC) The inputs are PNPs providing the high impedance necessary for interfacing with CMOS Outputs have high voltage capability minimum .

Features

output transistor protection if the VCC supply is lost by forcing the output into the high impedance OFF state with the same breakdown levels as when VCC 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 VCC e 5V Features Y Y Y Y Y Y CMOS compatible inputs High impedance inputs PNP’s High output voltage breakdown 56V min High output .
