• Low-Voltage µC Communication
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. 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 x 3 mm, SON package with
operation characterized from -40°C to 125°C.
