Full-duplex RS-485 transceiver for 5 V industrial links
The 50 mV of receiver hysteresis provides noise margin on long cable runs with ground potential differences.
25 Mbps signaling and full-duplex bus architecture
Full-duplex operation means the SN65HVD53D maintains separate transmit and receive paths simultaneously, unlike half-duplex transceivers that require direction control on a shared pair. At 25 Mbps the driver can support high-throughput protocols like Profibus or custom serial links over distances where the cable capacitance and termination still allow clean edges. The 50 mV hysteresis on the receiver input rejects noise coupled onto the bus, reducing bit errors without external filtering.
For dual-sourcing or alternate-footprint designs, the SN65HVD53D is a pin-compatible member of the 65HVD53 family; verify the full order code against your BOM line.
