Rated for -40°C to 85°C operation, this comparator is specified for outdoor telecom cabinets, factory-floor sensor interfaces, and engine-bay electronics where the ambient temperature swings beyond commercial limits. The quiescent current maxes at 320 µA, keeping the thermal budget low in densely populated boards.
The MAX9141EKA+T carries an Active lifecycle status and is ROHS3 compliant. No end-of-life notice is on record.
A comparator with latch holds the output state on a latch-enable signal, making it useful for sampled-data systems such as peak detectors, zero-crossing sampling, and overcurrent fault capture where the decision must be held for a subsequent logic read.
Yes, the output type is CMOS push-pull and TTL-compatible, so it can drive logic inputs directly without an external pull-up resistor.
The MAX9141EKA+T is a single comparator with latch in a SOT-23-8 package. The MAX9142EKA+T is a dual comparator with latch in the same package footprint. The key difference is the number of comparators per package: one versus two.
