RS-232 transceiver for multi-port serial links
The Maxim Integrated MAX214EWI+ is a full-duplex RS-232 transceiver packing three drivers and five receivers into a single 28-pin SOIC package. It handles serial data at 116 kbps over a 4.5 V to 5.5 V supply rail, with 500 mV of receiver hysteresis for noise rejection on longer cable runs. The 3/5 driver/receiver count suits equipment needing more receive channels than transmit — think multi-drop instrumentation, point-of-sale terminals, or industrial control panels where one UART talks to several peripheral devices.
116 kbps — what it means for the serial link
At 116 kbps this transceiver handles serial data for terminal servers and barcode scanners. The 500 mV hysteresis maintains clean edges on longer cable runs.
Package and footprint
Housed in a 28-SOIC wide-body (7.50 mm width) package, surface-mount only. The 0.295-inch body width is the wider SOIC variant — verify your PCB footprint matches the 7.50 mm body. Operating temperature range is -40°C to +85°C.
