What this comparator brings to the board
The Maxim Integrated MAX941ESA+ is a single high-speed comparator with a built-in latch and a shutdown pin — a combination that saves you an external flip-flop and a power switch when you need to sample a threshold and then go quiet. It pushes CMOS, push-pull, or TTL outputs, so it talks directly to logic without a pull-up resistor. Propagation delay is 80 ns max, which puts it in the fast lane for overcurrent detection, zero-crossing detectors, and pulse-width discriminators in industrial controls or telecom line cards.
80 ns — what that delay buys you
Maximum propagation delay is 80 ns.
Latch and shutdown — two features that matter on site
The latch holds the output state when the LE (latch enable) pin is asserted. That is useful in a sampled system — you grab the comparison result at a clock edge and hold it for the rest of the cycle. The shutdown pin drops quiescent current from 700 µA to near zero, which matters in battery-backed or power-shared designs. Both pins are active-low and TTL-compatible, so a GPIO or a simple RC timer can drive them.
Supply and temperature — fits the industrial rack
Single-supply range from 2.7 V to 5.5 V. Input offset voltage is 2 mV max at 5.5 V, and input bias current is 0.15 µA max.
Package and handling — field-swappable?
8-SOIC, surface-mount. Pin 1 is clearly marked on the package top. The 0.154-inch body width is standard SOIC-8.
Lifecycle and compliance — active, no LTB worry
The MAX941ESA+ is listed as Active with RoHS3 compliance. No end-of-life notice or last-time-buy window is on record.
