Product details

RS485 bus transceiver with wide supply range

The MAX3471EUA+ is a half-duplex RS485/RS422 transceiver from Analog Devices, integrating one driver and one receiver in a single 8-uMAX/uSOP package.

Data rate and receiver margin

The transceiver supports a maximum data rate of 64 kbps, which is the ceiling for the RS485 bus timing — the actual throughput depends on cable length, termination, and the number of nodes on the bus. Receiver hysteresis is specified at 32 mV, providing noise immunity on the differential bus lines. This margin prevents chatter on the receiver output when the input differential voltage is near zero, reducing false edges on long cable runs.

Frequently asked questions

Where can I buy MAX3471EUA+?

The MAX3471EUA+ can be sourced through independent distribution.

What is the maximum data rate of MAX3471EUA+?

The maximum data rate is 64 kbps. This is the RS485 bus timing limit; actual throughput depends on cable length, termination, and node count.

Does MAX3471EUA+ require external termination resistors?

Yes, like all RS485 transceivers, the MAX3471EUA+ requires external termination resistors at the ends of the bus to match the characteristic impedance of the cable and prevent signal reflections. The resistor value is typically 120 ohms for a twisted-pair cable.

How many devices can be connected on an RS485 bus with MAX3471EUA+?

The MAX3471EUA+ is a single-driver, single-receiver transceiver (1/1). On an RS485 bus, the number of nodes is limited by the driver's load capability and the receiver's input impedance. Standard RS485 allows up to 32 unit loads; the MAX3471EUA+ presents one unit load, so up to 32 such transceivers can be connected on a properly terminated bus.
