VCC = 3 V to 3.6 V, One input at VCC – 0.6 V,
Other inputs at VCC or GND
All typical values are at VCC = 3.3 V, TA = 25
°
C.
For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions.
§Unused pins at VCC or GND
The parameter II(hold) includes the off-state ouput leakage current.
#This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
