Frequently Asked Questions
How many frequency division stages does SN74HC4040ANS provide and what division ratios are available?
SN74HC4040ANS contains 12 binary ripple counter stages, providing division ratios from divide-by-2 up to divide-by-4096 at successive Q outputs. Each stage divides the input clock by 2, so designers can tap any of the 12 outputs to obtain the desired prescaled frequency.
Is SN74HC4040ANS compatible with both 3.3 V and 5 V logic systems in mixed-supply designs?
Yes. The 74HC CMOS logic family supports a supply voltage range of 2 V to 6 V, so SN74HC4040ANS can operate at either 3.3 V or 5 V, enabling direct interfacing with both TTL-compatible and modern low-voltage logic devices in the same system.
What is the reset behavior of SN74HC4040ANS and how quickly can the counter clear its state?
SN74HC4040ANS features an asynchronous active-high reset input that immediately clears all 12 counter stages regardless of clock state. The propagation delay through the 74HC family is typically a few nanoseconds, allowing rapid counter reset in high-speed timing and synchronization applications.
In what package is SN74HC4040ANS supplied and how does it simplify PCB integration?
SN74HC4040ANS is supplied in a small-outline (SOP) surface-mount package, which allows placement on both sides of a PCB and supports automated reflow soldering. The compact footprint with standard 1.27 mm pin pitch makes it straightforward to route all 12 output pins to downstream logic on a dense board.
