FUNCTIONAL DESCRIPTION

FIGURE 1- HI-8105 Oscillator

APPLICATION INFORMATION

The HI8105 and HI-8106 are 16 stage serial counters.

Each stage'sQ is input toa1 of 16 decoder. A4 bit code at

pins4 through7 selects which stage is routed to the output

at pin 3. The counter clocks on the negative transition of

pin 8.

Figure1 shows the oscillator circuit of the HI-8105. The

charging time is controlled bya delay circuit and the

hystersis window. The window is typically 0.6V wide at

VDD=5.0V.

Figure2 shows the bonding option which omits the N

device pulldown and thereby allows the simple clock input

of the HI-8106.
