The Intersil HCTS160T 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 low-to-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. |
