It supports data rates up to 230kbps, which is sufficient for most legacy serial peripherals, PLC programming ports, and terminal interfaces. Operating from a 4.5V to 5.5V supply, it integrates the charge-pump capacitors internally to generate the RS232 voltage levels, reducing external component count.
This is a stable line item for BOM planning. The surface-mount package keeps assembly straightforward.
No. The lifecycle status is Active, so Analog Devices has not announced an end-of-life for this part. It remains a current production item.
The ADM202EARWZ is a functional equivalent to the MAX202 family — same 2/2 driver/receiver count, same 5V supply, same 16-SOIC footprint. Pin compatibility should be verified against the specific MAX202 variant's datasheet, but the ADM202 is a common drop-in substitute for MAX202 designs.
It is rated for 230kbps, which covers standard RS232 speeds up to 115.2kbps and leaves margin for higher-rate links like 230.4kbps.
