Additional Details:

The TC74VHC125FT is typically supplied in a small outline integrated circuit (SOIC) package, indicated by the "FT" suffix. The device features four independent buffer gates, each with its own enable input. When the enable input is low, the output is enabled, and the input signal is passed through to the output. When the enable input is high, the output is in a high-impedance state. The propagation delay of the TC74VHC125FT is typically in the nanosecond range, making it suitable for high-speed applications. Detailed electrical characteristics, timing diagrams, and package dimensions can be found in the Toshiba datasheet.
