Introduction :
74HC160 is a synchronous presettable decade counter with an internal look-ahead 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 positive-going edge of the clock. Presettakes place regardless of the levels at count enable inputs (CEP and CET). A LOW at the masterreset input (MR) sets Q0 to Q3 LOW regardless of the levels at input pins CP, PE, CET and CEP(thus providing an asynchronous clear function).
The look-ahead carry simplifies serial cascadingof the counters. Both CEP and CET must be HIGH to count. The CET input is fed forward to enablethe terminal count output (TC).
