Additional preview pages of the HD74LV161A datasheet.

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.

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) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25°C) Output current ±6 mA (@VCC = 3.0 V to 3.6 V), ±12 mA (@VCC = 4.5 V to 5.5 V) HD74LV161A Function Table Inputs CLR L H H H H H LOAD X L H H H X ENP X X X L H X ENT X X L X H X CLK X ↑ ↑ ↑ ↑ ↓ Outpu.
