Working Principles

The 74LCX126SJX is a buffer/line driver IC that amplifies and shapes digital signals. It operates at low voltage levels, making it ideal for use in portable electronic devices. The inputs (A1-A4) control the state of the outputs (Y1-Y4), which can be enabled or disabled using the OE1 and OE2 inputs. When the output enable inputs are high, the outputs are in a high-impedance state, allowing other devices to drive the shared bus. The Schmitt-trigger input provides noise immunity by ensuring reliable signal detection even in the presence of electrical noise.
