DC CHARACTERISTICS FOR 74HCT
For the DC characteristics see
“74HC/HCT/HCU/HCMOS Logic Family Specifications”.
Transfer characteristics are given below.
Output capability: standard
ICC category: MSI
Note to HCT types
The value of additional quiescent supply current (
ICC) for a unit load of 1 is given in the family specifications.
To determine
ICC per input, multiply this value by the unit load coefficient shown in the table below.
TRANSFER CHARACTERISTICS FOR 74HCT
Voltages are referred to GND (ground = 0 V)
AC CHARACTERISTICS FOR 74HCT
GND = 0 V; tr =tf = 6 ns; CL = 50 pF
