The SN65HVD24P is officially obsolete per the manufacturer's product status. There is no official TI-released successor order code recorded for this specific variant. The SN65HVD24P sits in a large family of 5V RS-485 transceivers; a pin-compatible functional replacement within the SN65HVD2x family may exist, but without a manufacturer-issued cross-reference, substitution requires comparing the full parametric table (data rate, fail-safe biasing, output drive, thermal limits) and preferably validating on the target board.
3 Mbps half-duplex RS-422/485 in an 8-pin DIP
The 3 Mbps data rate covers most industrial fieldbus and building-automation links — Modbus RTU at 115.2 kbps or Profibus at 12 Mbps are well outside this chip's speed grade, so check the baud rate before committing.
