Holt Integrated Circuits has the largest ARINC 429 IC product portfolio in existence today. Holt’s ARINC 429 ICs cover a whole range of complexity, from simple analog bus interface chips such as line receivers and line drivers, to protocol ICs with on-chip FIFOs or RAM. Holt’s unique approach provides fully integrated solutions with both analog transceivers and digital protocol on one chip. The latest line of ARINC 429 terminal ICs are designed to operate from a single 3.3V supply and incorporate a host Serial Peripheral Interface (SPI). The latest line drivers and line receivers both have internal lightning protection to RTCA/DO-160G, Section 22 Level 3 pin injection test.
