74HC161 ( Presettable synchronous 4-bit binary counter-asynchronous reset) Micro SD Card the blades closeIntroduction : 74HC161 is a synchronous presettable binary counter with an internal look head carry. Synchronous operation is provided by having all flip flops clocked simultaneously on the positive going edge of the clock (CP). The outputs (Q0 to Q3) of the counters may be preset HIGH or LOW. A LOW at the parallel enable input (PE) disables the counting action and causes the data at thedata inputs (D0 to D3) to be loaded into the counter on the
