Product details

Why the 42 Mbps data rate matters for your bus

The MAX14783EESA+T is a half-duplex RS-485 / RS-422 transceiver from Analog Devices, rated for 42 Mbps (cite:). At that speed the cable length must be short — the RS-485 standard trades distance for rate, so a 42 Mbps link is a backplane or intra-cabinet run, not a long-haul field bus. The supply voltage spans 3V to 5.5V (cite:), which means it runs on either a 3.3V or 5V rail without a secondary regulator. The receiver hysteresis is 10 mV (cite:) — this is the noise margin on the differential input. In a noisy industrial environment, that hysteresis prevents the receiver from chattering on slow or noisy edges.

The part is ROHS3 compliant (cite:), so it passes the material declaration for EU markets without an exemption claim.

Lifecycle status is Active (cite:). That means Analog Devices has no current plan to end production — no last-time-buy trigger, no qualification of a replacement required for the BOM line. Cut Tape is also listed for prototype or low-volume builds.

Frequently asked questions

Is MAX14783EESA+T compatible with 3.3V logic?

Yes. The supply voltage range is 3V to 5.5V (cite:), so it runs directly on a 3.3V rail. The logic inputs and outputs swing with VCC, so a 3.3V supply gives 3.3V logic levels — no level shifter needed.

Can MAX14783EESA+T replace MAX485?

The MAX485 is a 2.5 Mbps RS-485 transceiver. The MAX14783EESA+T runs at 42 Mbps (cite:) and has a wider supply range (3V to 5.5V vs 5V only). Pin compatibility depends on the specific MAX485 variant — check the pinout of your existing footprint before substituting. The higher speed may also require termination and stub-length control that a slower MAX485 design did not need.
