3.3-V RS-485 transceiver with 1.65-V I/O supply & selectable data rate

The SN65HVD01 is a low-power, 250 kbps or 20 Mbps data rate selectable RS-485 transceiver, utilizing a 1.65-V to 3.6-V supply for data and enable signals, and a 3.3 V ± 10% supply for bus signals. The device is designed for applications requiring synchronous (parallel transceiver) signal timing. On-chip transient suppression protects the device against destructive IEC 61000 ESD and EFT transients.

The device combines a differential driver and a differential receiver, connected internally to form a bus port suitable for half-duplex (two-wire bus) communication. The device features a wide common-mode voltage range making it suitable for multi-point applications over long cable runs. The SN65HVD01 is available in a tiny, 3 mm × 3 mm, SON package with operation characterized from –40°C to 125°C.
