Product details

RS-232 interface for 5V serial links

The MAX202CSE+: The receiver hysteresis is specified at 500 mV, providing noise immunity on the serial line.

5V-only supply — plan the rail

The supply range is 4.5V to 5.5V, so this part is strictly a 5V device. It will not run from a 3.3V rail. If your system uses 3.3V logic, you need level translation on the UART lines or a different transceiver. The 120 kbps data rate is adequate for legacy RS-232 links at 9600 baud or 115200 baud, but not for higher-speed protocols.

Frequently asked questions

Is MAX202CSE+ compatible with MAX232?

The MAX202CSE+ is functionally similar to the industry-standard MAX232 — both are 5V RS-232 transceivers with 2 drivers and 2 receivers in a 16-pin SOIC. Pin compatibility should be verified against the respective datasheets, but the general function and footprint are the same.

What is the data rate of MAX202CSE+?

The MAX202CSE+ supports a data rate of 120 kbps.

Can MAX202CSE+ be used with 3.3V logic?

The supply voltage range is 4.5V to 5.5V, so the part itself requires a 5V supply. Direct connection to 3.3V logic without level shifting is not recommended; the input thresholds are referenced to the 5V rail.
