INPUT AND OUTPUT EQUIVALENT CIRCUIT
PIN DESCRIPTION
TRUTH TABLE
* When one or both controls are high, the eight input/output terminals are the high impedance state: howewer sequential operation or cleaning
of the register is not affected.
Z : High Impedance
Qn0 : The level of An before the indicated steady state input conditions were established.
Qnn : The level of Qn before the most recent active transition indicated by OR
a, h : The level of the steadystate inputs A, H, respectively.
X : Don’t Care
