Two enable inputs (TE and PE) and SYNCHRONOUS 4 BIT BINARY PRESETTABLE CARRY output are provided to enable easy COUNTER fabricated with silicon gate C2MOS cascading of counters, which facilities easy technology. implementation of N-bit counters without using The CLOCK input is active on the rising edge. external gates. Both LOAD and CLEAR inputs are active LOW. All inputs are equipped with protection circuits Presetting is synchronous on the rising edge of against static discharge and transient excess the clock, the function is synchronous to the voltage.
