DS3631 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 VCC (approximately VCC)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 A

The outputs are Darlington connected transistors This al-lows high current operation (300 mA max) at low internal VCC 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=5V power is 28 mW with both outputs ON V_CC operating range is 45V 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= 5V
