20Mbps single RS485 receiver — why the 15 mV hysteresis matters
The ISL3282EFRTZ-T: At 20Mbps, the 15 mV receiver hysteresis gives enough noise margin on long differential pairs to reject reflections without adding propagation delay.
Supply range spans 3V to 5.5V, so the same BOM position works on a 3.3V or 5V bus without a dedicated regulator. The single receiver topology suits point-to-point or multi-drop RS485 buses where only one node listens; for full-duplex or multi-receiver designs, the RAA7884QR4GSP#AB0 offers four receivers on the same protocol but at 80Mbps and in a different package — not a pin-for-pin swap.
Product status is Active, meaning Renesas continues to accept production orders through standard distribution. The part is ROHS3 compliant.
8-TDFN footprint — layout callout
Package is 8-WFDFN exposed pad, 2x3 mm body. The exposed pad must be connected to ground (or VEE) with at least four thermal vias — the pad also serves as the primary heat path.
