Holt Integrated Circuits
 
HI****3 / HI****4
Holt Integrated Circuits continues its support of the MIL-STD****3 data bus with a true single chip, dual 3.3V transceiver. Using proven design techniques and state-of-the-art analog CMOS technology, the new HI****3 dissipates only **0mW when transmitting at **0% duty cycle while still delivering the required power to the bus.
Each set of receiver outputs can also be independently forced to the bus idle state (logic '0' on HI****3 or logic '1' on HI****4) by setting RXENA or RXENB low.

The part is available in a small, **-pin SOIC package with an integrated metal heat sink in the base of the device that ensures adequate heat dissipation in even the most demanding environments. Measuring only 0.5 x 0.4 inches, and only 0.1 inch thick, the HI****3 offers the smallest board footprint available for this function, and is small enough even for PCMCIA applications.

The devices may be used with standard MIL-STD****3 transformers with a 1:2.5 turns ratio for direct coupled and 1:1.*9/1:1.4 turns ratios for transformer coupled bus connections.

Samples of the HI****3 and HI****4 are readily available in the small thermally enhanced plastic SOIC as well as in the traditional **-pin ceramic DIP package.
