∗
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.
‡ 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.
