Technical details

Supply voltage flexibility — 3.3V or 5V bus without a translator

The 3.15V to 5.5V supply range means this transceiver can be powered from a standard 3.3V rail in a mixed-voltage system or from a 5V rail in legacy industrial networks. This is a practical advantage when the same PCB design must support both 3.3V and 5V variants across different product tiers.

Package and footprint — 8-SOIC, hand-solderable

The 1.27 mm pin pitch is easy to route on a two-layer PCB. For a maker or small-run project, the SOIC-8 footprint is breadboard-friendly with a SOIC-to-DIP adapter — no fine-pitch or BGA challenges.
