MISSION VIEJO, Calif. – Holt Integrated Circuits in Mission Viejo, Calif., is introducing an enhanced version of the company's HI-35980 family of 8-channel ARINC 429 line receivers for commercial aviation avionics applications.

Holt has expanded the user-programmable label filtering capability of the avionics databus interface from 16 labels to all 256 labels, and increased the 4-word deep receive FIFO to 32 words deep.

In addition, Holt has added a 32-word deep transmit FIFO to increase the transmit capability from the single-word buffer on the existing device.

The avionics databus device is available in an industrial temperature range of -40 to 85 degrees Celsius, and an extended temperature range of -55 to 125 C., with optional burn-in at the higher temperature. Samples are available from Holt on request.
