The BINARY COUNTER fabricated with silicon gate counters are cleared by high levels on their clear C2MOS technology. lines. It consists of two identical internally synchronous The counter can be cascaded in the ripple mode 4-stage counters. The counter stages are D-TYPE by connecting Q4 to the enable input of the flip-flops having interchangeable CLOCK and subsequent counter while the clock input of the ENABLE inputs for incrementing on either the latter is held permanently low. positive-going or negative-going transition. All inputs are equipped with protection circuits For single-unit operation the ENABLE input is against static discharge and transient excess maintained "high" and the counter advances on voltage.
