Product details

That speed suits legacy serial links in point-of-sale terminals, industrial HMIs, and telecom equipment where the interface is still RS-232 but the baud rate needs to push past the classic 115.2 kbps ceiling.

Pin-compatible within the MAX3222 family

The MAX3222ECPWG4 is pin-compatible with the standard MAX3222E across the 20-TSSOP footprint. If your BOM calls for the industrial range, check the suffix — the 'E' in the middle of the order code here indicates the commercial grade.

Package and temperature — fits indoor, controlled environments

For outdoor or under-hood applications, you would need an industrial-rated sibling.
