Product details

RS-232 link at 250 kbps — what this transceiver brings to the board

The 300 mV receiver hysteresis cleans up noisy lines from long cable runs, a common pain in industrial serial links. Packaged in a 16-SOIC (7.50 mm wide body), it suits surface-mount assembly on standard PCB footprints.

That means no end-of-life notice is in effect, no last-time-buy window to chase.

Supply range and temperature — where it fits

If your design lives inside a terminal, a printer, a point-of-sale station, or a lab instrument, this temperature band is fine.

Frequently asked questions

What is the difference between MAX3232CDWR and MAX3232CSE?

Both are the same base MAX3232 transceiver, but the CDWR is in a wide-body 16-SOIC (7.50 mm width) while the CSE uses a narrow-body 16-SOIC (3.90 mm width). The package width is the only difference that affects the PCB footprint.
