With two drivers and two receivers, this transceiver handles a standard dual RS-232 port. The 3V to 5.5V supply range lets it interface directly with 3.3V logic without a level shifter, simplifying the power rail design. The 250 kbps data rate is typical for legacy serial protocols like Modbus RTU or terminal interfaces.
Texas Instruments does not list a single official replacement for the MAX3232EIDBG4. The MAX3232 family includes active variants in the same 16-SSOP footprint — check the MAX3232EIDB or MAX3232EIDBR for similar specifications. Confirm pin compatibility and electrical ratings before substituting.
