It delivers CMOS, push-pull, rail-to-rail, and TTL-compatible outputs, making it a flexible signal-threshold detector for battery-powered instrumentation, portable medical devices, and industrial sensor interfaces. The part operates over a 2.5 V to 5.5 V single supply (or ±1.25 V to ±2.75 V dual supplies) and across the -40°C to +85°C industrial temperature range.
The 450 ns maximum propagation delay sets the comparator's speed: it can cleanly resolve a 1 MHz input square wave, but it is not a high-speed part for RF or fast-switching power loops. For most threshold-detection and zero-crossing circuits in the kilohertz range, this delay is well within budget. The 24 µA maximum quiescent current keeps the power draw low, which matters when the comparator runs continuously on a battery rail. The 1 pA typical input bias current at 5.5 V means the part will not load down high-impedance sources like photodiode or pH probe outputs. The ±3 mV hysteresis is built in, so the buyer does not need external positive feedback resistors to prevent chatter at the switching threshold. The 80 dB typical CMRR and PSRR indicate the comparator rejects common-mode and supply-noise variations well enough for general-purpose signal conditioning.
