New MIL-STD-1553 Terminal with Integrated Transformers for XMC/PMC Applications
10/25/2016
Holt Integrated Circuits announced today a new lower profile 3.3V MIL-STD-1553 terminal solution, designed specifically to meet the component height requirements of XMC and PMC assemblies. Measuring just 15 x 15 x 4.4 mm, the HI-2130LBxx is the world's smallest single package 1553 terminal with integrated transformers. The new HI-2130 BGA package is available in both RoHS compliant and Sn/Pb configurations, giving customers a solution for tin-lead assemblies without expensive re-balling.   Read more
Octal ARINC 429 Line Receiver Family with Built-In DO-160G Level 3 Lightning Protection
1/28/2016
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.   Read more
First MIL-STD-1553 Dual Transceiver with Bus Tail-Off Compensation
12/16/2015
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.   Read more
Drop-In Replacement for DDC MIL-STD-1553 Transceiver BU-67401L
12/8/2015
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.   Read more
