Product details

250 kbps data rate — what it means for the bus

At 250 kbps, this transceiver is sized for reliable communication over longer cable runs. The slew-limited output reduces EMI and reflections.

Full-duplex with 100 mV hysteresis

Full-duplex operation requires two twisted pairs. The 100 mV receiver hysteresis prevents oscillation on a floating bus and adds noise immunity on long cables.

Supply and temperature range

The 3V to 3.6V supply range is narrow — this is a 3.3V-only part, not a 5V-tolerant transceiver. If your system runs a 5V bus, you need a level translator or a different part. The -40°C to 125°C operating range qualifies it for outdoor telecom cabinets, engine-bay electronics, and any environment where the ambient temperature swings wide. No AEC-Q100 grade is listed in the record, so if automotive qualification is required, verify that separately.

Lifecycle and sourcing posture

The MAX3070EASD+T is listed as Active with ROHS3 compliance.

Frequently asked questions

Can I use MAX3070EASD+T as a replacement for MAX3082 or MAX3471?

No direct pin-compatible replacement is cited in the record. The MAX3082 is a half-duplex RS-485 transceiver at 10 Mbps, and the MAX3471 is a half-duplex RS-485 at 250 kbps — both differ in duplex mode and speed. Evaluate the full-duplex requirement and data rate before cross-referencing.

What is the footprint of MAX3070EASD+T?

The package is 14-SOIC with a 3.90 mm body width (0.154"). The supplier device package is also 14-SOIC. Standard SOIC-14 footprint applies.
