Housed in a 20-TQFN (5x5) package with an exposed pad for thermal relief, this part is a surface-mount fit for compact PCB layouts. The -40°C to 85°C operating range covers industrial environments—motor drives, outdoor telecom cabinets, and unheated enclosures—without needing a commercial-grade workaround.
The MAX3223EETP+ carries an Active product status and is ROHS3 compliant.
The MAX3232 is also a 2/2 RS232 transceiver but typically operates at a higher data rate (up to 1 Mbps) and uses a different pinout. The MAX3223EETP+ is specified for 250 kbps and has a 500 mV hysteresis, which can be advantageous in noisy environments. They are not pin-compatible, so a board redesign is needed to swap.
