IINPUT AND OUTPUT EQUIVALENT CIRCUIT
PIN DESCRIPTION
TRUTH TABLE
* When one or both output controls are high, the eight input/output terminals are in the high impedance state: however sequential operation
or clearing 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
a, h : The level of the steady state inputs A, H, respectively.
X : Don’t Care
