NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-
INGS may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions
above those indicated in the operational sections of this specification is
not
implied. Exposure to absolute maximum rating conditions for
extended periods may affect reliability. No terminal voltage may exceed
V
CC
by +0.5V unless otherwise noted.
2. Input and V

terminals only.
3. Outputs and I/O terminals only.
NOTE:
1. This parameter is measured at characterization but not tested.

Description
The D flip-flop data inputs.
When the clear input is LOW and
OE
is
LOW, the Q
I
outputs are LOW. When
the clear input is HIGH, data can be
entered into the register.
Clock Pulse for the Register; enters
data into the register on the LOW-to-
HIGH transition.
The register 3-state outputs.
Clock Enable. When the clock enable is
LOW, data on the D
I
input is transferred
to the Q
I
output on the LOW-to-HIGH
clock transition. When the clock enable
is HIGH, the Q
I
outputs do not change
state, regardless of the data or clock
input transitions.
Output Control. When the
OE
input is
HIGH, the Y

OE
input is
LOW, the TRUE register data is present
at the Y

outputs.
