† All typical values are at VCC = 5 V, TA = 25°C.

‡ This parameter is specified by characterization.

§ The parameters IOZH and IOZL include the input leakage current.

¶ For VCC between 2.1 V and 4 V, OE should be less than or equal to 0.5 V to ensure a low state.

# Not more than one output should be tested at a time, and the duration of the test should not exceed one second.

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