Jarwey is a Tier-1 distributor of COSINE—selection support, datasheets, sampling & small batch, lead-time coordination.

COSINE general-purpose comparators cover automotive, industrial, sensor, and consumer designs that need 2.5–36 V open-drain multi-channel thresholds. For low-voltage high-speed / low-power / nano-power splits, use the other comparator family notes published alongside this one.

Datasheets from Jarwey. LM339 / LM2903 / LM393 are common second-source evaluation anchors—verify before lock-in.

Product features

Low offset, low latency, speed/power balance, wide supply range.

Applications (vendor-stated)

Automotive · industrial · sensors · consumer electronics.

Checklist before freeze

Rail: do you need up to 36 V?
Channel count: dual COS393 / LM2903SR vs quad LM339SR.
Open-drain pull-up: resistor, level, EMC.
Speed tier: if 67 ns is not enough, move to HS/LP families instead of forcing this tier.
Samples: request datasheet and samples from Jarwey.
