Working Principles

The SN74ALVC126DR is a buffer IC that amplifies and drives digital signals. It consists of four independent buffers, each capable of driving a separate signal line. The 3-state outputs allow the buffers to be enabled or disabled, enabling multiple devices to share a common bus without interfering with each other.

When the Output Enable (OE) pin is low, the outputs (Y1-Y4) are active and reflect the input signals (A1-A4, B1-B4). When OE is high, the outputs are in a high-impedance state, effectively disconnecting them from the bus.
