Product details

RS-232 transceiver for mixed-voltage serial links

The 250 kbps data rate covers most industrial serial protocols (RS-232 at 115.2 kbps, 230.4 kbps) with margin.

Rated from 3V to 5.5V, the MAX3232IDW runs directly off a 3.3V rail or a 5V rail without a regulator, which simplifies the power tree.

Lifecycle status — active, no obsolescence watch needed

No last-time-buy or date-code provenance concerns apply.

Frequently asked questions

What is the difference between MAX3232IDW and MAX3232CDW?

The MAX3232IDW and MAX3232CDW share the same 2/2 driver/receiver count, 250 kbps data rate, and 3V–5.5V supply range. The IDW is the drop-in replacement for the CDW when extended temperature operation is required.
