(1)
On products compliant to MIL-PRF-38535, this parameter is not production tested at VCC = 0 V.
(2)
For I/O ports, the parameter IOZ includes the input leakage current.
(3)
This is the increase in supply current for each input at one of the specified TTL voltage levels, rather than 0 V or VCC.
SWITCHING CHARACTERISTICS
over recommended operating free-air temperature range, VCC = 5 V ± 0.5 V (unless otherwise noted) (see Figure 1)
