This means the manufacturer has announced end-of-life and is accepting final orders within a defined window. For a production BOM, this triggers a last-time-buy planning exercise: secure enough inventory to cover the remaining build horizon, or qualify a replacement before the buy window closes. The part is still available through independent distribution on a quoted-to-order basis, but the clock is running on fresh factory shipments.
Supply rail and data rate — fit check for the design
If your existing bus runs on a 5V rail, this part needs a local 3.3V regulator. At 32 Mbps the driver slew rate is fast enough for short, point-to-point links (up to a few metres) but expect signal degradation on long multi-drop stubs without proper termination. The 35 mV hysteresis helps keep the receiver from chattering on a lightly loaded bus.
