NOTES:
1. For conditions shown as Min. or Max., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at V
3. Per TTL driven input. All other inputs at V
4. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.
5. Values for these conditions are examples of ΔI
6. I
NOTES:
1. Propagation Delays and Enable/Disable times are with V
2. See test circuit and waveforms.
3. Minimum limits are guaranteed but not tested on Propagation Delays.
