Description

The Intersil HCS161MS is a Radiation Hardened 4-Input Binary; synchronous counter featuring asynchronous reset and lookahead 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 and is used to enable the next cascaded stage to count.
