Active quad RS485 receiver — 80 Mbps on a 3V to 5.5V rail
The RAA7884QR4GSP#AB0 is a dedicated quad RS422/RS485 receiver in a 16-SOIC narrow-body package, not a transceiver — it has four receivers and zero drivers on chip (0/4 count per). This matters for BOM planning: if your bus node only needs to listen (monitor bus traffic, receive broadcast commands, or interface to an isolated receive-only port), this part saves the cost and board area of an unused driver stage. Rated for 80 Mbps data rate, it handles high-speed industrial fieldbus links and backplane communication where propagation delay across long cables is the limiting factor, not the receiver itself. The 30 mV hysteresis provides noise rejection on long RS485 stubs — a practical margin for factory-floor wiring where common-mode noise couples into the twisted pair.
Supply flexibility and temperature grade for mixed-voltage and harsh environments
This is a practical BOM simplification when the rest of the board runs at 3.3V but the fieldbus interface still expects 5V-tolerant inputs. The 125°C ceiling means the receiver's input thresholds and hysteresis stay within datasheet limits even when ambient temperature pushes past 105°C — common in sealed junction boxes on a sunny factory roof.
Active lifecycle — no last-time-buy clock ticking
ROHS3 compliant — no restricted substance exemptions that would limit shipping to EU, UKCA, or other RoHS-enforced markets. The compliance documentation covers the standard Renesas environmental declaration package.
16-SOIC narrow-body — standard footprint, no board spin
If your existing layout already uses a 16-SOIC RS485 quad receiver, this part drops in without a PCB revision — confirm the pinout matches your current receiver footprint before committing. Surface mount mounting with tube packaging — the tube format is typical for prototype and low-to-medium volume assembly; for high-volume reels, check the ordering options under the same base part number.
