DS1631 - 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 interfa
