Description
These synchronous, presettable, 4-bit decade and binary counters feature an internal carry look-ahead circuitry for application in high-speed counting designs. The SN54ALS162B is a 4-bit decade counter.
Key Features
- an internal carry look-ahead circuitry for application in high-speed counting designs
- The SN54ALS162B is a 4-bit decade counter
- The ’ALS161B, ’ALS163B, ’AS161, and ’AS163 devices are 4-bit binary counters
- This mode of operation eliminates the output counting spikes normally associated with asynchronous (ripple-clock) counters
- A buffered clock (CLK) input triggers the four flip-flops on the rising (positive-going) edge of the clock input waveform
