Working Principles

The SN74AHCT126DGVR is a quad buffer gate that amplifies and buffers digital signals. It operates using CMOS technology, which ensures low power consumption and high-speed performance. The inputs (A1-A4) are amplified and the outputs (Y1-Y4) are driven to match the input signal levels. The output enable (OE) pin controls the state of the outputs, allowing them to be either active or in a high-impedance state.
