Product details

RS485/RS422 full-duplex transceiver — what it is and where it fits

The Maxim Integrated MAX1481CUB+ is a single RS422/RS485 transceiver with one driver and one receiver, running full duplex over a single twisted pair. It handles signaling up to 250 kbps.

Receiver hysteresis — 70 mV of noise margin

The receiver includes 70 mV of hysteresis, which helps reject noise on long cable runs common in RS485 installations.

Package and footprint — 10-uMAX/uSOP

Housed in a 10-lead uMAX/uSOP package (3.00 mm width, 0.118" pitch), this is a compact surface-mount part suited for dense PCBs. The supplier device package is listed as 10-uMAX/uSOP.

Sourcing and lifecycle — active, no LTB watch needed

It is ROHS3 compliant. For current availability and pricing, we source this through independent distribution channels — confirmed at quote time against an RFQ. No stock or lead-time figures are published here; submit an RFQ for a real-time quote.

Frequently asked questions

Is MAX1481CUB+ equivalent to MAX3485?

No, they are not equivalent. The MAX1481CUB+ is a 5 V full-duplex transceiver at 250 kbps, while the MAX3485 family typically operates at 3.3 V and offers data rates from 250 kbps up to 12 Mbps depending on the suffix. Pin compatibility varies by package variant; always check the respective datasheets before substituting.

What is the data rate for MAX1481CUB+?

The maximum data rate is 250 kbps. This is sufficient for most RS485 fieldbus applications at standard baud rates (9600, 19200, 115200) but not for high-speed protocols like Profibus at 12 Mbps.
