Product details

The MAX9140AAXK+T: Its 40 ns maximum propagation delay makes it a candidate for overcurrent detection, zero-crossing circuits, and level translation where the comparator's decision needs to settle inside a fast control loop. The output stage is CMOS push-pull or TTL-compatible, so it drives logic inputs without a pull-up resistor — one less BOM line.

Quiescent current maxes at 400 µA, so it won't blow the sleep-mode budget in a battery-powered sensor node.

Package and footprint — SC-70-5 for tight boards

Housed in a 5-lead SC-70 (SOT-353), the MAX9140AAXK+T occupies roughly 2 mm × 2 mm of board area. That footprint suits multi-channel comparator arrays, handheld instruments, and any design where PCB real estate is the constraint.

Frequently asked questions

Is MAX9140AAXK+T compatible with 3.3V?

The comparator operates from a single 3.3 V supply with no additional level shifting needed for the output.
