NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS 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.

Description
Clock input
Gate control for Qn outputs. When
G
is LOW, these outputs are enabled. When
G
is HIGH, these outputs are asynchronously
disabled to the level designated by GL
(1)
.
Specifies output disable level. If HIGH, the outputs disable HIGH. If LOW, the outputs disable LOW.
Clock outputs
Power supply for the device core, inputs, and outputs
Power supply return for power
NOTE:
1. Because the gate controls are asynchronous, runt pulses are possible. It is the user's responsibility to either time the gate control signals to minimize the possibility of runt
pulses or be able to tolerate them in down stream circuitry.

1. Skew measured between all outputs under identical input and output transitions and load conditions on any one device.
2. Skew measured is the difference between propagation delay times t
