HD74LV161A Synchronous 4-bit Binary Counter (Direct Clear) REJ03D0319–0400Z (Previous ADE-205-264B (Z)) Rev.4.00 Jun. 04, 2004 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 the data on the A, B, C .

HD74LV161A Synchronous 4-bit Binary Counter (Direct Clear) REJ03D0319–0400Z (Previous ADE-205-264B (Z)) Rev.4.00 Jun. 04, 2004 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 the 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. Features • VCC = 2.0 V to 5.5 V operation • All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) • All outputs VO (Max.) = 5.5 V (@VCC = 0 V) • Typica.
