RS-232 link, 20-SOIC, 250 kbps ceiling
The MAX3222CDWR: Data rate is rated at 250 kbps — sufficient for legacy serial ports, industrial terminal links, and configuration interfaces where the bus runs at 115.2 kbaud or below. The 300 mV receiver hysteresis filters noise on long cable runs without external schmitt triggers.
Active production, ROHS3, and sourcing posture
ROHS3 compliant — no exemptions for lead in solder, which simplifies EU and UKCA declarations for finished goods.
