The TC7LX1108WBG does not have a control signal that controls the direction of data flow between A and B. In

a DC state, the output circuit holds either High or Low level, but since it is designed to have a weak drive strength

(with a typical output resistance of 5.5 kΩ), an overdrive signal from the external driver can change the direction

of data flow.

The output one-shot circuits detect either a rising or falling edge on the A or B port. During the rise time, the

output one-shot circuit associated with the PMOS transistors turns it on for a certain period to speed up a

transition from Low to High. Likewise, during the fall time, the output one-shot circuit associated with the NMOS

transistors turns it on to speed up a transition from High to Low.
