The HI-15690 family is a 5V, single channel MIL-STD-1553 transceiver, whereas the HI-15691 family is a dual channel version. All devices guarantee a minimum transformer-coupled output voltage of 20Vp-p, making them also suitable for MIL-STD-1760 applications.
“Product obsolescence is a major concern for our customers, incurring significant cost for re-design and qualification," said George Noh, Director of Sales and Marketing at Holt Integrated Circuits. “The availability of second source 'form, fit and function' drop-in replacements gives our customers the option to mitigate these costs.”
Samples are available now upon request from Holt.
