74HC/HCT03
DC CHARACTERISTICS FOR 74HCT
For the DC characteristics see
“74HC/HCT/HCU/HCMOS Logic Family Specifications”, except that the VOH values are
not valid for open drain. They are replaced by IOZ as given below.
Output capability: standard (open drain), excepting VOH
ICC category: SSI
Voltages are referenced to GND (ground = 0 V)
Note
1. The maximum operating output voltage (VO(max)) is 6.0 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
ICC per input, multiply this value by the unit load coefficient shown in the table below.
AC CHARACTERISTICS FOR 74HCT
GND = 0 V; tr =tf = 6 ns; CL = 50 pF
