74LVC161 : The 74LVC161 is a high–performance, low–power, low–voltage, Si–gate CMOS device and superior to most advanced CMOS compatible TTL families. The 74LVC161 is a synchronous presettable binary counter which features an internal look–head carry and can be used for high–speed counting. 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 to a HIGH or LOW level. A LOW level at the parallel enable input (PE) disables the counting action and causes the data at the data inputs (D0 to D3) to be loaded into the counter on the positive–going edge of the clock (provided that the.

74LVC161 : The 74LVC161 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 the data inputs (D0 to D3) to be loaded into the counter on the positive-going edge of the clock. Preset takes place regardless of the levels at count enable inputs (CEP and CET). A LOW at the master reset input (MR) sets Q0 to Q3 LOW regardless of the levels at input pins CP, PE, CET and CEP (thus providing an asynchrono.
