On products compliant to MIL-PRF-38535, this parameter is not production tested.
All typical values are at VCC = 3.3 V, TA = 25
°
C.
Unused terminals are at VCC or GND.
§This is the bus-hold maximum dynamic current. It is the minimum overdrive current required to switch the input from one state to another.
This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
