DESCRIPTION
The Intersil 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 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. The HCS161MS utilizes advanced CMOS/SOS technology to achieve high-speed operation.
