A new range of Profibus transceivers offer low signal distortion and improved reliability

The SN65HVD1176 and SN75HVD1176 transceivers provide improved output transition skew of less than 1ns (0.2ns typical), giving system designers the ability to tighten up the total timing budget of their networked applications. The HVD1176 also features high ESD protection of 10kV and fail-safe for open, idle and shorted bus conditions, which are ideal for demanding industrial applications.

'Among other reasons, Siemens chose the HVD1176 because it allows our designers to control the timing aspect of the automation process to a greater degree', said Manfred Sand, Siemens A and D AS RD.

'The SN65HVD1176 driver output transition skew is so tight that it can be used for special diagnostic functions'.

TI's HVD1176 half-duplex transceivers are designed for Profibus and RS485 networks.

Powered by a 5V supply, it is fully compliant with the EN50170 and TIA/EIA485 standards.

With low skew during output transitions and driver enabling/disabling, this device is suitable for signalling rates up to 40Mbit/s over long twisted-pair cables.

The HVD1176 also provides excellent common-mode rejection up to 50MHz.

The SN65HVD1176 and SN75HVD1176 are available now from TI and its authorised worldwide distributors in an 8-pin SOIC package.

Suggested resale pricing is $1.40 in quantities of 1000.
