Full-duplex transceivers with robust 3.3V drivers and receivers
Expanding its RS-485 portfolio, Texas Instruments (TI) has introduced a new
family of full-duplex transceivers with robust 3.3V drivers and receivers
and high levels of ESD protection.
The ESD protection includes > 30kV HBM and >±12kV 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
The devices each combine a differential driver and a differential receiver,
which operate from a single 3.3V power supply. Each driver and receiver has
separate input and output pins for full-duplex bus communication designs.
The devices feature a wide common-mode voltage range which makes the devices
suitable for multi-point applications over long cable runs.
