HD74LV161A
Synchronous 4-bit Binary Counter (Direct Clear)
ADE-205-264A (Z) 2nd Edition June 1999 Description
The HD74LV161A is 4-bit binary counters.
All flip flops are clocked simultaneously on the low to high to transition (positive edge) of the clock input waveform.
These counters may be preset using the load input.
Presetting of all four flip flops is synchronous to the rising edge of clock.
When load is held low counting is disabled and tha data on the A, B, C and D inputs is loaded into the counter on the rising edge clock.
If the load input is taken high before the positive edge of clock the count operation will be unaffected.
Low-
voltage and high-speed operation is suitable for the...
