FAQ

What is the function of the G inputs on the TC7WT240FUTE12LF?

The G inputs serve as active-low output enables. When these inputs are low, the buffers are enabled; when high, the outputs enter a high-impedance state.

How does the input threshold voltage support TTL compatibility?

The device specifies a minimum high-level input voltage (VIH) of 2.0 V and a maximum low-level input voltage (VIL) of 0.8 V, allowing direct interfacing with TTL output drivers.
