RS232 interface IC for serial communication
The MAX221ECUE+ is a single RS232 transceiver from Analog Devices, providing one driver and one receiver in a full-duplex configuration. The 500 mV receiver hysteresis filters out noise on the incoming RS232 line, reducing false edges on longer cable runs where signal integrity degrades.
Housed in a 16-lead TSSOP package with 0.65 mm pitch and 4.40 mm body width, the MAX221ECUE+ fits a standard SOIC footprint with a smaller land pattern. The surface-mount package suits automated assembly lines and dense PCB layouts where board space is constrained. Supplied in tube packaging, the part is suited for prototype builds and low-to-mid volume production runs where tray or tape-and-reel handling is not required. The ROHS3 compliance ensures the solder joints meet current environmental directives without process exceptions.
RoHS3 compliance is confirmed, covering all six original restricted substances plus the four phthalates added under EU 2015/863. No exemption declarations or lead-bearing finish applies — the part ships fully compliant for global markets including EU, UKCA, and China RoHS.
