Working Principles

The SN74LV21ADGVR is a dual 4-input AND gate that performs logical AND operations on its four input signals. It utilizes high-performance CMOS technology, which enables fast switching speeds and low power consumption. The Schmitt-trigger inputs ensure noise immunity by providing hysteresis to the input signals.

When all four inputs are high (logic level 1), the output of the gate becomes high. Otherwise, the output remains low (logic level 0). The gate operates within a wide supply voltage range, allowing it to be used in various applications.
