* On products compliant to MIL-PRF-38535, this parameter does not apply.

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

‡ This parameter is characterized, but not production tested.

§ 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.
