Product details

The MAX942EUA+ is a dual general-purpose comparator with push-pull CMOS/TTL output. It runs off a single 2.7 V to 5.5 V supply and delivers an 80 ns max propagation delay. 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

ROHS3 compliant, so it passes EU material declarations without an exemption review.

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.

Frequently asked questions

Is MAX942EUA+ obsolete?

No. The manufacturer lists this part as Active. No discontinuation notice or last-time-buy window is in effect.

Is MAX942EUA+ a direct replacement for LM393?

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.

Does MAX942EUA+ come in tape and reel packaging?

The standard shipment form is Tube. Tape-and-reel packaging may be available as an alternate packing option — specify the requirement at quote time so the supplier can confirm the reel quantity and lead time.

Is MAX942EUA+ RoHS compliant?

Yes. It is rated ROHS3 Compliant, meaning no restricted substances above the threshold limits and no exemption for lead in solder.
