The SN65HVD10DG4 carries a Last Buy status, meaning TI has stopped accepting new orders and the final production window is closing. Any remaining inventory in the channel is the last available supply. For new designs or long-running production, identify a pin-compatible replacement before the LTB window shuts.
32 Mbps half-duplex transceiver in 8-SOIC
It handles a 32 Mbps data rate, making it suitable for high-speed industrial fieldbus links, motor-drive encoder interfaces, and building-automation backplanes.
What the 32 Mbps data rate means for bus timing
At 32 Mbps the bit period is about 31 ns. Propagation delay and cable skew eat into the timing budget faster than at lower rates. For a 32 Mbps RS-485 link, keep the stub length under 0.3 m and use a properly terminated twisted pair. The half-duplex nature means the driver and receiver share the same pair — the bus turnaround time (driver disable to receiver enable) must be accounted for in the protocol state machine.
Package and footprint notes for layout
The surface-mount footprint is standard SOIC-8 with 1.27 mm pitch. The thermal pad is not present — all dissipation goes through the leads, so keep the copper pour on the supply pin generous if the ambient runs near the 85°C limit.
