Product details

RS-232 link in a compact SSOP-16

The MAX3221EAE+T is a single-driver, single-receiver RS-232 transceiver in a 16-pin SSOP package. It handles full-duplex serial communication at data rates up to 235 kbps, which covers the standard UART speeds up to 230.4 kbps with margin for the start/stop framing overhead. The 300 mV receiver hysteresis filters noise on the incoming RS-232 line, reducing the chance of false edge triggers on a long cable run.

The surface-mount assembly flows with standard reflow profiles; the tape-and-reel delivery feeds pick-and-place without a reel change.

Sourcing and lifecycle posture

The tape-and-reel format suits volume production runs.
