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.
Features

Notes: The absolute maximum ratings are values which must not individually be exceeded, and furthermore, no two of which may be realized at the same time. 1. The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. This value is limited to 5.5 V maximum. 3. The maximum package power dissipation was calculated using a junction temperature of 150C.
