Product details

RS-232 link with single-supply flexibility

The MAX3221ECAE+T: Data rate is rated at 250 kbps, sufficient for legacy serial ports, industrial terminal interfaces, and configuration links where the protocol overhead stays below this ceiling.

Receiver hysteresis and signal integrity

Receiver hysteresis is specified at 500 mV, providing noise rejection on the RS-232 line. This margin reduces the chance of bit errors when the cable runs through electrically noisy environments like motor drives or switching power supplies. Full-duplex operation means the driver and receiver paths are independent, so the part handles simultaneous transmit and receive without external direction control.

Package, temperature grade, and supply posture

The supplier device package is also 16-SSOP, so the PCB footprint matches standard SSOP-16 land patterns.
