category: MSI
Non-standard DC characteristics for 74HCT
Voltages are referenced to GND (ground = 0 V)
Note to HCT types
The value of additional quiescent supply current (∆I
CC
) for a unit load of 1 is given in the family specifications.
To determine ∆I
CC
per input, multiply this value by the unit load coefficient shown in the table below.
