Working Principles

The SN74HC08DBR is a quad 2-input AND gate that performs logical AND operations on two input signals. It utilizes high-speed CMOS technology to achieve fast propagation delay times and low power consumption. The Schmitt-trigger input ensures reliable operation by providing noise immunity.

When both input signals are high, the output of the gate becomes high. Otherwise, the output remains low. The open-drain outputs require an external pull-up resistor to provide a logic high level when the output is not actively driven low.
