Applications
The SN74LV4040ADG4 is commonly used as a frequency divider in clock distribution networks, prescaler circuits, and timing reference generators in embedded systems and communications equipment. Its 12-bit binary counting enables division of high-frequency clocks down to precise lower frequencies for microcontroller peripherals, ADC sampling clocks, and display refresh circuits. The low-voltage LV family compatibility makes it suitable for 3.3V and 5V mixed-signal board designs in industrial and consumer electronics.

Frequently Asked Questions
What is the maximum operating frequency of the SN74LV4040ADG4?
The SN74LV4040ADG4 operates at a maximum frequency of 50MHz at nominal supply voltage. This makes it suitable as a binary counter and frequency divider for clock generation, prescaling, and event counting applications in embedded systems, communications, and test equipment operating in the tens of megahertz range.
How many bits does the SN74LV4040ADG4 counter have?
The SN74LV4040ADG4 is a 12-bit binary counter, providing division ratios of 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, and 4096 from its individual output pins. This makes it highly versatile for generating multiple divided clock frequencies from a single input clock source.
Is the SN74LV4040ADG4 synchronous or asynchronous?
The SN74LV4040ADG4 is an asynchronous (ripple) counter, meaning each flip-flop stage is clocked by the output of the previous stage rather than a common clock. This ripple architecture introduces small propagation delays between output bits but simplifies the design and reduces power consumption compared to synchronous counters.
What package is the SN74LV4040ADG4 available in?
The SN74LV4040ADG4 is packaged in a 16-pin Small Outline Integrated Circuit (SOIC) as indicated by JESD-30 code R-PDSO-G16. This surface-mount package with a 1.27mm lead pitch is compatible with standard PCB footprints and high-speed automated assembly, making it a practical choice for production boards.
