(1) VI = VIH or VIL, unless otherwise noted.
(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.
(3) SN54HCT125 is in product preview.
(4) On products compliant to MIL-PRF-38535, this parameter is not production tested.
