flip-flops with individual D-type inputs and 3-STATE true
outputs. The device is byte controlled with each byte func-
tioning identically, but independent of the other. The control
pins can be shorted together to obtain full 16-bit operation.
Each byte has a buffered clock and buffered Output Enable
common to all flip-flops within that byte. The description
which follows applies to each byte. Each flip-flop will store
the state of their individual D inputs that meet the setup and
hold time requirements on the LOW-to-HIGH Clock (CP
n
)
transition. With the Output Enable (OE
n
) LOW, the con-
tents of the flip-flops are available at the outputs. When
OE
n
is HIGH, the outputs go to the high impedance state.
Operation of the OE
n
input does not affect the state of the
flip-flops.

Note 3:
The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated
at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the Absolute Maximum Ratings. The “Recom-
mended Operating Conditions” table will define the conditions for actual device operation.
Note 4:

Absolute Maximum Rating must be observed.
Note 5:
