HI-8045

The HI-8045 high voltage display driver is a low cost plastic, 80-segment version of the Holt HI-8040 display driver series. The 20 mil package lead pitch allows the maximum number of display driver segments in the smallest space. An optional voltage converter can generate the negative display drive voltage. Test inputs facilitate opens and shorts testing. The backplane frequency is checked and, as long as power is available, the segments are shut "Off" if the frequency becomes too low.

The HI-8045 and the HI-80XX series of display drivers all control segment information in the same way. Data is serially clocked into the HI-8045 and the data for all segment outputs are latched in parallel when the Load input transitions from high to low. With the Data Out from the shift register available, devices may be cascaded to obtain more segment outputs. The shift register is 85 bits long. The die is metal mask programmable to provide for various package and/or cascade tap options. Consult your Holt Sales representative to explore the possibilities.
