SLLSEH0F – JULY 2013 – REVISED AUGUST 2014
SN65HVD01 3.3V RS-485 with Flexible I/O Supply and Selectable Speed
1 Features
1 Exceeds Requirements of TIA-485 Standard
• 1.65-V to 3.6-V Supply for Data and Enable
Signals
• 3-V to 3.6-V Supply for Bus Signals
• SLR Pin Selectable Data Rates: 250 kbps or 20
Mbps
• 1/8th Unit Load to Support up to 256 Nodes on a
Bus
• Small 3 mm x 3 mm SON Package
• Failsafe Receiver (Bus Open, Bus Shorted, Bus
Idle)
• Operating Temperature Range: –40°C to 125°C
• Bus-Pin Protection More Than:
– ± 15kV HBM Protection
– ± 16kV IEC61000-4-2 Contact Discharge
– ± 16kV IEC61000-4-2 Air Discharge
– 4kV IEC61000-4-4 Fast Transient Burst
2 Applications
• Telecom Infrastructure
• High-Speed Data Links
• Low-Voltage µC Communication
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. 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.
