SN54LV163A
Key Features
- an internal carry look ahead for application in high-speed counting designs
- The ’LV163A devices are 4-bit binary counters
- 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 ’LV163A devices is synchronous
- A low level at the clear (CLR) input sets all four of the flip-flop outputs low after the next low-to-high transition
