pF

(1)

Not more than one output should be tested at a time, and the duration of the test should not exceed 2 ms.

(2)

This is the increase in supply current for each input that is at one of the specified TTL voltage levels, rather than 0 V or VCC.

4.5 Switching Characteristics

over recommended operating free-air temperature range, VCC = 5 V ± 0.5 V (unless otherwise noted) (see Load Circuit and
