Intersil HCTS193MS
HCTS193MS is a Radiation Hardened 4-bit binary UP/DOWN synchronous counter. The counter is incremented on the low to high transition of the clock-up input (high on the clock-down), decremented on the low to high transition of the clock-down input (high on the clock-up). The Terminal Count Up goes low half a clock period before the zero count is reached and returns high at the maximum count.| Part No. | HCTS193MS |

DESCRIPTION
The Intersil Presetting the counter to the number on the preset data inputs (P0 - P3) is accomplished by a low on the asynchronous parallel load input (PL). A high level on the MR input overrides any other input to clear the counter to zero. The Terminal Count Down mode goes low half a clock period before the maximum count and returns high at the maximum count.
