The Intersil HCTS193MS is a Radiation Hardened 4-bit binary UP/DOWN synchronous counter.
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). 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). A high level on the MR input overrides any other input to clear the counter to zero. The Terminal Count Up goes low half a clock period before the zero count is reached and returns high at the maximum count. The Terminal Count Down mode goes low half a clock period before the maximum count and returns high at the maximum count.
The HCTS193MS utilizes advanced CMOS/SOS technology to achieve high-speed operation. This device is a member of radiation hardened, high-speed, CMOS/SOS Logic Family.
The HCTS193MS is supplied in a 16 lead Ceramic flatpack (K suffix) or a SBDIP Package (D suffix).
