3.3V ARINC 429 Line Receiver Offers Exceptional Input Common-Mode Performance

Wednesday, November 24, 2004

The HI-8591 and HI-8591-40 ARINC 429 Line Receivers are the latest in Holt’s introduction of 3.3 Volt ARINC 429 databus interface products. These new products are designed with high impedance inputs to minimize bus loading, and have exceptional input common-mode performance in excess of +/- 30 volts, making them immune to ground offsets around the aircraft. The HI-8591-40 variant enables easy addition of external lightning protection circuitry, thus simplifying board designs where lightning protection is a concern. Both devices are available in small 8-pin SOIC and ultra-small 4mm x 4mm LPCC chip-scale packages with temperature screening and processing from Industrial to Full Military.

Mission Viejo, CA (November 24, 2004) –Holt Integrated Circuits today announced the introduction of their newest 3.3 volt ARINC 429 CMOS products with the release of the HI-8591 and HI-8591-40 Line Receivers. The HI-8591 is a highly integrated CMOS bus interface receiver designed to operate from a single 3.3 volt or 5 volt supply. The part is designed with high-impedance inputs to minimize bus loading, and has exceptional input common-mode performance in excess of ± 30V, making it immune to ground offsets around the aircraft.

Like other Holt ARINC 429 Receiver products, the 3.3V HI-8591 is offered in a “-40” variant to simplify the circuit design in applications where lightning protection may be a concern. The HI-8591-40 requires only the addition of external 40KOhm resistors in series with RINA and RINB to allow the part to meet the pin injection lightning protection requirements of DO-160D, level 3.

The HI-8591 and HI-8591-40 are available in the very popular 8-pin plastic SOIC and an ultra-small 16-pin 4mm x 4mm LPCC Chip-scale package. Other package options in both plastic and ceramic configurations are available to meet alternative customer requirements, with temperature screening and processing from Industrial to full Military.

“Holt has seen a growing demand for 3.3 volt databus products,” says Sandy Edberg, Sales Director at Holt. “While continuing to support the long-term production and customer support of our industry standard 5 volt products, we are successfully implementing our strategy to expand our line of 3.3 volt products for both our ARINC 429 and MIL-STD-1553 product lines.”

Holt Integrated Circuits has the largest selection of ARINC 429 ICs available from any supplier. Products range from simple line drivers and receivers to complete single-chip terminals. Screening options include Industrial and full Military temperature ranges. Holt’s ARINC 429 products are available in a wide selection of package options, from traditional ceramic packages to state-of-the-art thermally enhanced plastic small-outline styles, and now ultra-small chip-scale packages. Whatever the ARINC 429 design requirements, Holt has the optimum solution for your next design. The HI-8591 has been released to production, and product samples are available now.
