19-1226; Rev 0; 4/97 Single/Dual/Quad, Micropower, Ultra-Low-Voltage, Rail-to-Rail I/O Comparators _______________General Description ____________________________Features The MAX965–MAX970 single/dual/quad micropower Ultra-Low Single-Supply Operation down to +1.6V comparators feature Rail-to-Rail® inputs and outputs, and Rail-to-Rail Common-Mode Input Voltage Range fully specified single-supply operation down to +1.6V. These devices draw less than 5µA per comparator and 3µA Quiescent Supply Current per Comparator have open-drain outputs that can be pulled beyond V CC Open-Drain Outputs Swing Beyond VCC to 6V (max) above ground. In addition, their rail-to-rail input common-mode voltage range makes these com- 1.235V ±1.5% Precision Internal Reference parators suitable
