Product details

RS-232 interface with a wide supply window

The Texas Instruments MAX3222CDW is a full-duplex RS-232 transceiver in a 20-SOIC wide-body package. The 300 mV receiver hysteresis provides noise immunity on longer cable runs typical of industrial serial links.

Temperature grade and deployment fit

It is not specified for extended industrial or automotive under-hood use — if the design sees -40°C or +85°C ambient, look at the industrial-grade variant in the same family.

Frequently asked questions

What is the difference between MAX3222CDW and MAX3222IDW?

Both share the same 20-SOIC package, 2/2 driver/receiver count, and 250kbps data rate.
