74LVTH273MTC

Low Voltage Octal D-Type Flip-Flop with Clear

Fairchild Semiconductor 

DC Electrical Characteristics (Continued)

Note 5: An external driver must source at least the specified current to switch from LOW-to-HIGH.

Note 6: An external driver must sink at least the specified current to switch from HIGH-to-LOW.

Note 7: This is the increase in supply current for each input that is at the specified voltage level rather than VCC or GND.
