(1)

Not more than one output should be tested at a time, and the duration of the test should not exceed 10ms.

(2)

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

4.5 Switching Characteristics

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

Voltage Waveforms)
