† _{All typical values are at VCC = 3.3 V, TA = 25°C.}
‡ _{Unused terminals 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.}
