RS232 transceiver with 200kbps data rate
The MAX242CWN+T: It handles serial data at 200kbps, making it a fit for legacy RS232 links in industrial control, point-of-sale terminals, and instrumentation where the protocol still dominates the backplane.
Package and board integration
Housed in an 18-SOIC wide-body (0.295-inch, 7.50mm width) — the wider body spreads the pin pitch to 1.27mm, easing hand-solder and inspection compared to the narrow SOIC. The supplier device package is 18-SOIC; the tape-and-reel option (MAX242CWN+T) suits automated pick-and-place for volume builds.
Receiver hysteresis and signal integrity
The receiver hysteresis is specified at 500 mV — this built-in noise margin rejects line glitches and slow-edge signals common on long RS232 cables. For a bench test, the hysteresis means the receiver does not chatter on a floating input; the output stays clean until the differential crosses the threshold band.
