Description
The Intersil HCS193MS 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 acplished 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 HCS193MS utilizes advanced CMOS/SOS technology to achieve high-speed operation. This device is a member of radiation hardened, high-speed, CMOS/SOS Logic Family.
