Product details

What this dual comparator brings to the board

The Maxim Integrated MAX942ESA+T is a dual, general-purpose comparator in an 8-SOIC package. It runs on a single supply from 2.7 V up to 5.5 V.

Temperature grade and environment

Rated for -40°C to 85°C, this part handles industrial environments — outdoor telecom cabinets, factory-floor sensor interfaces, and engine-bay-adjacent electronics that see temperature swings. The 8-SOIC package is a standard footprint, easy to hand-assemble or reflow, and the surface-mount body keeps board area small.

Lifecycle and sourcing reality

The MAX942ESA+T carries an Active lifecycle status and is ROHS3 compliant. For dual-sourcing or a pin-compatible second source, verify the specific suffix for your BOM.

Frequently asked questions

What is the output type of MAX942ESA+T?

Outputs are CMOS, push-pull, and TTL-compatible. No external pull-up resistor is needed when driving logic inputs.

Can MAX942ESA+T replace MAX942?

The MAX942ESA+T is a specific tape-and-reel variant of the MAX942 dual comparator family. It is functionally the same die in the same 8-SOIC package, with the same 80 ns propagation delay and 2.7 V to 5.5 V supply range. Verify the output type and temperature grade match your BOM requirements before substituting.
