Product details

42Mbps half-duplex RS-485/RS-422 transceiver in 8-SOIC

The MAX14783EASA+ is a single-channel half-duplex transceiver supporting both RS-485 and RS-422 protocols, delivering up to 42 Mbps on a 3V to 5.5V supply rail. Receiver hysteresis is specified at 10 mV, giving noise immunity on long cable runs where ground potential differences accumulate.

Industrial temperature range and 5V supply compatibility

At 5V the driver output differential meets the RS-485 minimum of 1.5V across the common-mode range, even under full load. 42 Mbps is the maximum data rate — at this speed the cable length is limited by signal attenuation rather than the driver slew rate. For longer runs, reducing the baud rate to 10 Mbps or below extends reach to 4000 ft per the RS-485 standard.

Supplied by Analog Devices (formerly Maxim Integrated) in tube packaging.

Frequently asked questions

Is MAX14783EASA+ compatible with 5V systems?

Yes — the supply voltage range of 3V to 5.5V means it operates directly on a 5V rail. The RS-485 driver output meets the 1.5V minimum differential across the common-mode range at 5V, and the receiver inputs tolerate up to -7V to +12V common-mode per the RS-485 standard.

Is the MAX14783EASA+ a half-duplex transceiver?

Yes — it is a half-duplex transceiver with one driver and one receiver. The driver output and receiver input share the same bus pins; the driver is tri-stated when the device is listening.
