250 ns propagation delay — what it buys the signal chain
The MAX9077EKA/GH9-T is a dual general-purpose comparator from Maxim, built for low-power threshold detection and level translation. Its 250 ns typical propagation delay is fast enough for most sensor interrupt, over-voltage latch, and zero-crossing circuits running below a few hundred kHz, without the power penalty of a high-speed comparator. The push-pull, CMOS, and TTL-compatible output drives logic inputs directly — no external pull-up resistor needed, which saves a component and a trace on the board.
5.2 µA quiescent — the power budget anchor
Common-mode rejection is 82 dB typical, with 77 dB PSRR, adequate for noisy supply rails in mixed-signal designs.
Housed in an SOT-23-8 package, the MAX9077EKA/GH9-T occupies minimal board area — roughly 3 mm × 3 mm — and suits high-density layouts. Surface-mount assembly is standard; no thermal pad or exposed paddle to plan for. The input offset voltage is 8 mV max at 5 V, so budget that into the threshold accuracy for low-margin sense points.
