description/ordering informationThe ’HC4040 devices are 12-stage asynchronous binary counters, with the outputs of all stages available
externally. A high level at the clear (CLR) input asynchronously clears the counter and resets all outputs low.
The count is advanced on a high-to-low transition at the clock (CLK) input. Applications include time-delay
circuits, counter controls, and frequency-dividing circuits.
ORDERING INFORMATION†Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are
available at www.ti.com/sc/package.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
