The Intersil HCS161MS is a Radiation Hardened 4-Input
Binary; synchronous counter featuring asynchronous reset
and look-ahead carry logic. The HCS161 has an active-low
master reset to zero, MR. A low level at the synchronous
parallel enable, SPE, disables counting and allows data at
the preset inputs (p0 -p3) to load the counter. The data is
latched to the outputs on the positive edge of the clock input,
CP. The HCS161MS has two count output, IC. The terminal
count output indicates a maximum count for one clock pulse …
