It runs off a single 2.7 V to 5.5 V supply and delivers an 80 ns max propagation delay. Industrial temperature range (-40°C to 85°C) covers factory-floor control cabinets, outdoor telecom pedestals, and HVAC controller boards. Not rated for under-hood automotive, but fine for any chassis-mounted or indoor industrial enclosure. ## 80 ns propagation delay — the speed decision At 80 ns max, this comparator is faster than a standard open-collector type. The trade-off: quiescent current sits at 600 µA max per package. ## Active part — no obsolescence pressure Lifecycle status is Active per the manufacturer. No last-time-buy notice, no NRND flag. That means you can qualify this part into a new BOM without worrying about a forced respin mid-production. ROHS3 compliant, so it passes EU material declarations without an exemption review. ## Package and footprint Housed in an 8-uMAX/uSOP (3.00 mm body width, 0.118\" pitch). Surface-mount only. Tube shipment is the default; confirm the reel option at quote time.","metaTitle":"MAX942EUA+ Dual General-Purpose Comparator, 80ns, 8-uMAX","metaDescription":"MAX942EUA+ dual comparator, 80ns propagation delay, 2.7V-5.5V single supply, push-pull output, -40°C to 85°C.

No discontinuation notice or last-time-buy window is in effect."},{"question":"Is MAX942EUA+ a direct replacement for LM393?","answer":"Pin-compatible in the same 8-pin SOIC/MSOP footprint, but the MAX942EUA+ is significantly faster (80 ns vs ~1.3 µs) and uses a push-pull output instead of open-collector. The push-pull stage eliminates the need for an external pull-up resistor, but the output logic levels are rail-to-rail rather than pulled up to a separate voltage. If your LM393 circuit relies on a pull-up to a different supply rail (e.g., 12 V), the MAX942EUA+ will not directly replace it without a circuit change."},{"question":"Does MAX942EUA+ come in tape and reel packaging?","answer":"The standard shipment form is Tube.
