Buffers, Drivers, Receivers, Transceivers FAQ

What technology ensures the quiet output switching performance?

The device utilizes Fairchild's FACT Quiet Series technology, which includes GTO output control and an undershoot corrector to guarantee quiet output switching and improved dynamic threshold performance.

How is the pin-to-pin skew defined for this device?

Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. This specification applies to any outputs switching in the same direction, either HIGH-to-LOW or LOW-to-HIGH.
