74HC163; 74 HCT163 Presettable synchronous 4-bit binary counter; synchronousresetRev. 5 12 October 2018 Product data sheet1. General descriptionThe 74HC163; 74 HCT163 is a synchronous Presettable binary counter with an internal look-headcarry. synchronous operation is provided by having all flip-flops clocked simultaneously on thepositive-going edge of the clock (CP). The outputs (Q0 to Q3) of the counters may be preset toa HIGH or LOW. A LOW at the parallel enable input (PE) disables the counting action. It causesthe data at the data inputs (D0 to D3) to be loaded into the counter on the positive-going edge ofthe clock. Preset takes place regardless of the levels at count enable inputs (CEP and CET).
