† All typical values are at VCC = 5 V.
‡ This data-sheet limit may vary among suppliers.
§ 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.
