New 3.3V MIL-STD-1553 Dual Transceiver with 1.8V, 2.5V and 3.3V Compatible Digital I/O

Tuesday, March 10, 2020

Mission Viejo, CA (March 10, 2020) – Holt Integrated Circuits today announced the introduction of HI-15850, the world’s first 3.3V MIL-STD-1553 dual transceiver with 1.8V, 2.5V and 3.3V compatible digital I/O. This feature gives users more flexibility to interface with a broad range of FPGAs, avoiding the use of level shifters and other additional circuitry. 



This new device is based on Holt’s popular HI-1585, providing the same unique features of bus tail-off compensation and receiver output pulse extension. Tail-off compensation provides a means to actively compensate for bus tail-off, which is an undesirable temporary DC offset on the terminal’s bus stub resulting from non-optimal board design and layout. The receiver output pulse extension feature ensures receiver output pulse widths remain above 180ns, improving receiver sensitivity for designs operating close to the minimum receiver input response amplitude and ensuring proper decoding.

As the use of embedded MIL-STD-1553 IP cores, such as Holt's HI-6300, become more prevalent, it is critical to provide our customers with a transceiver solution capable of seamlessly interfacing with modern FPGA technology,” said George Noh, Director of Sales and Marketing at Holt. “This new device will enable customers to use their existing FPGA digital I/O without the need for voltage conversion or other logic.” 

The HI-15850 is packaged in the industries smallest MIL-STD-1553 transceiver package, a 48-pin plastic 6 x 6mm QFN with an exposed heat sink pad, which may be soldered to the PCB ground plane for optimal thermal dissipation. The device is available in industrial −40oC to +85oC and extended −55oC to +125oC temperatures, with optional burn-in available on the extended temperature range.
