Product details

1 Mbps data rate and 500 mV hysteresis

The MAX3237ECDWR: At 1 Mbps, this transceiver sustains the full RS232 data rate for high-speed legacy serial links — think multi-drop UART buses or debug consoles on industrial controllers. The 500 mV receiver hysteresis filters noise on long cable runs, reducing false edges on the RX line.

28-SOIC wide-body footprint

Housed in a 28-SOIC (0.295", 7.50 mm width) surface-mount package, the MAX3237ECDWR mates with standard SOIC-28 wide footprints. The tape-and-reel option (also available in cut tape) suits both prototyping and volume pick-and-place assembly.

Frequently asked questions
