SLLSEI9G –MAY 2014–REVISED OCTOBER 2019
SN65HVD7x 3.3-V Full-Duplex RS-485 Transceivers with ±12-kV IEC ESD
These devices each combine a differential driver and
a differential receiver, which operate from a single
3.3-V power supply. Each driver and receiver has
separate input and output pins for full-duplex bus
communication designs. These devices all feature a
wide common-mode voltage range which makes the
devices suitable for multi-point applications over long
cable runs.

Extended industrial temperature range:
–40°C to 125°C
Large receiver hysteresis (70 mV) for noise
rejection
The SN65HVD70, SN65HVD73, and SN65HVD76
devices have active-high driver enables and active-
low receiver enables. A low, less than 5-µA standby
current can be achieved by disabling both the driver
and receiver.

D
These devices extend the RS-485 portfolio with a
family of full-duplex transceivers with robust 3.3-V
drivers and receivers and high levels of ESD
protection. The ESD protection includes > ±30-kV
HBM and > ±12-kV IEC61000-4-2 contact discharge.
The large receiver hysteresis of the SN65HVD7x
devices provides immunity to conducted differential
noise and the wide operating temperature enables
reliability in harsh operating environments. The
SN65HVD7x devices are offered in a standard SOIC
package as well as in a small-footprint MSOP
package.
