Description

The Intersil HCS160MS is a Radiation Hardened high speed presettable BCD decade synchronous counter that features an asynchronous reset and look-ahead carry logic. Counting and parallel presetting are accomplished synchronously with the lowto-high transition of the clock. A low level on the synchronous parallel enable input, SPE, disables counting and allows data at the preset inputs, P0 - P3, to be loaded into the counter. The counter is reset by a low on the master reset input, MR. Two count enables, PE and TE are provided for n-bit cascading. TE also controls the terminal count output, TC. The terminal count output indicates a maximum count for one clock pulse and is used to enable the next cascaded stage to count.
