Product details

Temperature range and environment

Rated -40°C to 125°C operating, which covers industrial enclosures, outdoor telecom cabinets, and under-hood automotive auxiliary boxes. The capacitive isolation technology holds up over that span with no wear-out mechanism tied to operating hours — unlike optocouplers, LED degradation isn't a concern here.

Lifecycle and sourcing

Marked active in production with ROHS3 compliance. No end-of-life notice on record, so it's safe to specify into a new BOM without an LTB watch. Sourced and quoted to order through independent distribution; availability and current pricing confirmed at quote time.

Frequently asked questions

Where can I buy MAX14932CASE+ and how do I get a price?

This part is sourced and quoted to order through independent distribution. Submit an RFQ for current availability and pricing — stock and price are confirmed at quote time.

Can MAX14932CASE+ be used with 3.3V logic?

Yes. The supply range is 1.71V to 5.5V, so it operates directly on a 3.3V rail without a level shifter. Both sides can run at 3.3V, or one side at 1.8V and the other at 5V.

How does MAX14932CASE+ compare to ADuM1401?

The MAX14932CASE+ uses capacitive coupling (vs. ADuM1401's iCoupler magnetic isolation) and offers a wider supply range down to 1.71V. Both are 4-channel, 2/2-direction parts in SOIC-16, but the MAX14932CASE+ has a higher CMTI of 25 kV/µs, which helps in noisy industrial environments.

What is the closest pin-compatible alternative to MAX14932CASE+?

The ADuM1401 is a functionally similar 4-channel digital isolator in the same SOIC-16 package, but it uses magnetic isolation and has a narrower supply range. No official second-source cross-reference is listed for this part.
