Working Principles

The CD74HCT126M96 is a quad bus buffer gate that operates using CMOS technology. It acts as a buffer between the input and output signals, providing amplification and isolation. The buffered inputs ensure that the input signal is not affected by the load connected to the output. The 3-state outputs allow multiple devices to share a common bus without interfering with each other.

The IC works based on the principle of logic gates, where the input signals are processed and amplified to produce the desired output. The output enable (OE) pin controls the output state, allowing the user to enable or disable the output as needed. This feature is particularly useful in bus systems where multiple devices need to share the same communication lines.
