HI-1579

Holt Integrated Circuits continues its support of the MIL-STD-1553 / 1760 data buses with a true single chip, dual 3.3V transceiver. Using proven design techniques and state-of-the-art analog CMOS technology, the new HI-1579 dissipates only 340mW when transmitting at 100% duty cycle while still delivering the required power to the bus.

The part is available in a small, 7mm x 7mm, 44-pin plastic QFN package as well as the 20-pin SOIC package. Both have an integrated metal heat sink in the base of the device that ensures adequate heat dissipation in even the most demanding environments. Both HI-1579 packages offers the smallest board footprint available for this function, and including PCMCIA applications.

The HI-1579 uses the same, industry standard 1:2.5 turns ratio transformer as Holts 5V parts.

Samples of the HI-1579 is readily available in the small thermally enhanced plastic QFN and SOIC as well as in the traditional 20-pin ceramic DIP package.
