The HI-8597 is a 3.3V single-supply ARINC 429 line driver equipped with internal lightning protection circuitry. The internal lightning protection circuitry allows compliance with RTCA/DO-160G, Section 22 Level 3. The internal 37.5Ω resistance for each output enables direct connection to the ARINC 429 bus. Additionally, this device includes a dual-polarity voltage doubler, allowing it to operate with just four external capacitors using a single +3.3V power supply. Other features include a high-impedance output (tri-state) when both data inputs are high, enabling multiple line drivers to be connected to a common bus. The bus pin has built-in 8kV ESD input protection (HBM), while all other pins are equipped with 6kV functionality. All logic inputs are compatible with 5V or 3.3V. The HI-8597 line driver is intended for use when there is a need to convert logic signals to ARINC 429 levels, such as when using FPGAs or the HI-3586 ARINC 429 protocol IC.

• Dedicated IC

The HI-8460 and HI-8461 are insulated single ARINC 429 line receivers equipped with internal lightning protection circuits. This device provides 800V isolation between the line receiver and the logic interface. It is an ideal device for protecting the host interface or for systems that require different grounds. While the power supply and ground are isolated between the line receiver and the logic interface, the IC only requires one 3.3V power supply and ground, making the HI-8460 pins compatible with Holt's existing line receivers, HI-8450, HI-8591, and HI-8588. Therefore, this device offers a cost-effective solution for adding galvanic isolation to existing designs.

• Other semiconductors

The HI-35930 from Holt is a CMOS integrated circuit designed to connect SPI-compatible microcontrollers to the ARINC 429 serial bus. This device features two receivers, each with user-programmable label recognition for any combination of 256 possible labels, a 32×32 receive FIFO, three priority label quick access double buffer registers, and an analog line receiver. Both line receivers meet the lightning protection requirements of RTCA/DO-160G, Section 22, Level 3. The independent transmitter includes a 32×32 transmit FIFO and an integrated line driver. The line driver operates on a single 3.3V power supply and includes an on-chip DC/DC converter that generates the bipolar ARINC 429 differential voltage levels necessary to directly drive the ARINC 429 bus. The status of the transmit and receive FIFOs and the priority label buffer can be monitored using a programmable external interrupt pin or by polling the status register.

• Other semiconductors

The internal transceiver allows for direct connection to the host bus without the need for external components, minimizing board space when combined with the host's SPI. ■HI-3111 This is the digital-only version of the HI-3110. An external transceiver is required separately. ■HI-3112 This model offers an option for a CLKOUT pin instead of a SPLIT pin, which can be used as the main system clock or as a clock input for other devices in the system. ■HI-3113 This provides all options (both CLKOUT and SPLIT pins) in a very compact QFN-44 package.

• Other semiconductors

The HI-8400 is an isolated 4-channel discrete-digital sensor designed to output sensor data via SPI or a parallel bus interface. The isolation provides 800V of separation between each sensor and the logic interface, making it an ideal device for systems that need to accommodate various grounds. Each input can be individually pin-configured as GND/OPEN or 28V/OPEN. The discrete input thresholds comply with Airbus ABD0100H and MIL-STD-704 specifications. This device operates with a digital power supply of 3.3V (±5%) or 5.0V (±5%) for each isolated sensor and a 28V analog power supply. When GND/OPEN mode is selected on its pin, a 1mA wetting current is supplied from the input network of each SENSE input. The wetting current helps prevent dry relay or switch contacts. The sensor output interrupt pin alerts the system to changes in the sensor input, avoiding the need for regular polling via SPI to check the status.

• Other semiconductors

The HI-2579/HI-2581 is a low-power CMOS dual transceiver designed to meet the requirements of MIL-STD-1553/MIL-STD-1760 specifications, featuring an integrated transformer. The dual transceiver with an integrated transformer provides a single-part solution for interfacing protocol ICs or FPGAs to a dual-redundant MIL-STD-1553 bus. This single-package solution significantly reduces footprint and cost, and its low-profile design makes it ideal for applications using cards with height restrictions for components such as PMC and XMC. ■ Japanese technical documentation on MIL-STD-1553 and ARINC 429 communication standards is available.
