3 Description

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. OnMbps

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 x 3 mm, SON package with operation characterized from -40°C to 125°C.
