What Does Active LOW Mean? - Peter Vis

WebNow we come to the idea of assertion. When a signal is asserted that means it is active, it is doing what its name says. You use assertion to describe the state of both active high and active low signals. RESET is asserted when it is active, which is HIGH. SET is asserted when it is active, which is LOW.

One of the inputs is called the SET input; the other is called the RESET input. Latch circuits can be either active-high or active-low. The difference is determined by whether the operation of the latch circuit is triggered by HIGH or LOW signals on the inputs.

WebAug 11, 2024 · Figure 12: Separate asynchronous reset networks for active low and active high resets to prevent glitch propagation (Source: vSync Circuits) A synchronous filter can provide longer filtering time (e.g., for manual button noise filtering).
