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 battery-powered products (e.g., notebook
computers), and the low-power consumption extends the battery life.
