1.

On the 74FCT163H501 these pins have bus hold.

2.

A-to-B data flow is shown. B-to-A data flow is similar but uses OEBA, LEBA, and CLKBA.

3.

H = HIGH Voltage Level

L = LOW Voltage Level

X = Don’t Care

Z = High-impedance

= LOW-to-HIGH Transition

4.

Output level before the indicated steady-state input conditions were established.

5.

Output level before the indicated steady-state input conditions were established, provided that CLKAB was HIGH before LEAB went LOW.

6.

Operation beyond the limits set forth may impair the useful life of the device. Unless otherwise noted, these limits are over the operating free-air temperature range.
