Product details

2.5 Mbps data rate and the bus budget

Receiver hysteresis of 50 mV provides noise immunity against ground shifts and reflections on the bus. That 50 mV deadband means the receiver output won't chatter when the differential input sits near zero — useful on long cables or in electrically noisy environments like motor-drive cabinets.

Industrial temperature range and supply rail

Rated from -40°C to 85°C, the MAX3486EESA+T is specified for factory-floor enclosures, outdoor telecom shelters, and engine-bay-adjacent electronics where the ambient temperature can climb. The 3V to 3.6V supply range matches 3.3V logic families directly — no level shift between the UART and the transceiver on a 3.3V MCU board.

Active production — no LTB planning needed

This part is listed as Active and ROHS3 compliant. There is no last-time-buy notice or end-of-life forecast.

Frequently asked questions

Can MAX3486EESA+T replace MAX3485EESA+T?

Both are half-duplex RS-485/RS-422 transceivers in the same 8-SOIC package and 3V to 3.6V supply range, but they differ in data rate. The MAX3486EESA+T runs at 2.5 Mbps, while the MAX3485EESA+T is a higher-speed variant (typically 10 Mbps). If your bus timing budget and cable length accommodate the lower rate, the MAX3486EESA+T is a drop-in pin-compatible substitute. Verify the data rate requirement in your application before swapping.

How does MAX3486EESA+T compare to SN65HVD12?

Both are 3.3V half-duplex RS-485 transceivers, but the SN65HVD12 from TI is typically rated for 1 Mbps, while the MAX3486EESA+T runs at 2.5 Mbps. The SN65HVD12 also offers higher receiver hysteresis (typically 100 mV) for better noise rejection on long cables. The MAX3486EESA+T is the faster option; the SN65HVD12 is the more robust choice for noisy, low-speed links.
