7A.
The 74HC/HCT162 are synchronous presettable decade counters which feature an internal look-ahead 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 (providing QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns TYPICAL SYMBOL tPHL PARAMETER propagation delay CP to Qn CP to TC CET to TC propagation delay CP to Qn CP to TC CET to TC maximum clock frequency input capacitance power dissipation capacitance per package notes 1 and 2 CONDITIONS HC CL = 15 pF; VCC = 5 V 19 21 11 19 21 11 63 3.
