Holt Integrated Circuits introduced today a new Octal ARINC 429 line receiver family with fully integrated lightning protection circuitry. The built-in circuitry ensures compliance with RTCA/DO-160G, Section 22 Level 3 Pin Injection Test Waveform Set A (3 & 4), Set B (3 & 5A) and Set Z (3 & 5B), enabling direct connection to the ARINC 429 bus without external components. The HI-8456 and HI-8457 are exact drop-in replacements for DEI1046 and DEI1047 respectively. The HI-8458 is pin-to-pin compatible with Holt’s popular HI-8448 and is also a drop-in replacement for the DEI1148.

Holt Integrated Circuits today announced the introduction of HI-1585, the first MIL-STD-1553 dual transceiver with tail-off compensation. MIL-STD-1553 bus tail-off or offset is a transmitter-induced phenomenon caused by imbalance in the transmit signal path. It causes a temporary DC offset on the terminal’s bus stub which can temporarily impair the terminal’s ability to decode received commands following transmission of long messages.

Holt Integrated Circuits today announced the introduction of HI-1584, a pin-compatible, “form, fit and function” drop-in replacement for the Data Device Corporation MIL-STD-1553 transceiver, BU-67401L0C0x-102. The new device is a dual-channel transceiver which may be paired with Holt MIL-STD-1553 isolation transformers, for example PM-DB2779.

Holt Integrated Circuits today announced it received an award from Ametek Aerospace and Defense, Power and Data Systems Division, for exceptional on-time-delivery (OTD) performance. The award recognizes Holt’s 100% on-time-delivery achievement for four straight quarters.

Holt Integrated Circuits today announced formal MIL-STD-1553 RT validation of MAMBA, the world’s smallest family of MIL-STD-1553 / MIL-STD-1760 multi-terminal devices. Validation was performed at Test Systems, Inc., an independent Air Force approved testing service for MIL-STD-1553 remote terminals. A validation report is available on request.

Holt announces the availability of four new application development kits for the recently released MAMBA family, the world’s smallest MIL-STD-1553/1760 integrated solution. All MAMBA devices have on-chip dual bus transceivers, 8K words static RAM (16-bit plus parity) and a 40 MHz Serial Peripheral host Interface (SPI).

Holt Integrated Circuits today announced the release of MAMBA, a new family of MIL-STD-1553 / MIL-STD-1760 devices in an ultra-compact form factor. The MAMBA family is available in a 48-pin PQFP or 6mm x 6mm QFN package, the world’s smallest MIL-STD-1553 integrated solution. Four devices are offered, providing various combinations of Bus Controller (BC), Monitor Terminal (MT) or Remote Terminal (RT) functions, with all options having a 40 MHz Serial Peripheral host Interface (SPI) and integrated dual transceivers on-chip.

Holt today announced a low profile MIL-STD-1553 fully integrated terminal solution. The device, HI-2130, contains MIL-STD-1553 protocol logic, dual transceivers and dual transformers in a low profile compact package.

Holt Integrated Circuits today added two new devices to its novel ARINC 429 receiver family designed specifically for use without a microprocessor. All configuration and control is programmed using logic input pins, eliminating the need for a microprocessor or software interface and the related costs for software certification. The new devices provide an optional parity check feature, discarding words received with parity errors.

Holt Integrated Circuits today announced the introduction of a new 3.3V MIL-STD-1553/1760 dual transceiver with integrated dual transformers. At less than 4.6mm when mounted, this new device, HI-2579CG, has the lowest height and footprint available on the market today and is an ideal choice for applications using cards with component height restrictions, such as PMC and XMC.
