RS-232 link in a 16-TSSOP footprint
The MAX3221EEUE+T is a single RS-232 transceiver from Analog Devices, handling one driver and one receiver in full-duplex mode at 250 kbps — the practical ceiling for legacy serial links where cable capacitance and slew-rate limits define the bit-error floor, not the silicon. The 16-TSSOP package (0.173" body width) places cleanly on a standard 0.65 mm pitch footprint — no tombstoning risk at reflow if the pad geometry matches the land pattern in the datasheet.
Supply rails and temperature grade
Industrial temperature qualification from -40°C to 85°C means the part holds its RS-232 output levels across a factory floor that cycles between a cold start and a warm cabinet. Receiver hysteresis of 500 mV filters noise on long cable runs — a 5-meter RS-232 cable in an electrically noisy environment still sees clean logic transitions at the receiver output.
ROHS3 compliant per the manufacturer's declaration — no exemption-based paperwork needed for EU-market equipment.
