SN74HC163-Q1 Overview
Key Features
- an internal carry look-ahead for application in high-speed counting designs
- The SN74HC163 is a 4-bit binary counter
- This mode of operation eliminates the output counting spikes normally associated with synchronous (ripple-clock) counters
- A buffered clock (CLK) input triggers the four flip-flops on the rising (positive-going) edge of the clock waveform
- The clear function for the SN74HC163 is synchronous
- This synchronous clear allows the count length to be modified easily by decoding the Q outputs for the maximum count desired
- The active-low output of the gate used for decoding is connected to CLR to sy
