Fairchild 74LVX125 Low-Voltage Quad Buffer with 3-STATE Outputs Data Manual
Summary
This Low Voltage Quad Buffer features four independent, non-inverting buffers with reliable 3-STATE outputs. It is engineered to solve complex signal integrity challenges by providing stable input voltage level translation, making it ideal for interfacing high-voltage systems (e.g., 5V) down to sensitive low-power 3.3V logic. The comprehensive manual provides engineers with all necessary data, including detailed electrical characteristics, recommended operating conditions across varied temperatures, and various package options required for robust system integration.
