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 mA
The outputs are Darlington connected transistors This allows high current operation (300 mA max) at low internal VCC current levels since base drive for the output transistor is obtained from
