Notes:
1.
*Before xLEAB LOW-to-HIGH Transistion
H = High Voltage Level
L = Low Voltage Level
X = Don’t Care or Irrelevant
Z = High Impedance
A-to-B data flow shown. B-to-A flow control is the same,
except using xCEBA, xLEBA, and xOEBA.

Note:
1.For the PI74FCT162H543T, these pins have “Bus
Hold.” All other pins are standard, outputs, or I/Os.
