DC CHARACTERISTICS FOR 74HCT
74HC/HCT595
For the DC characteristics see chapter
“74HC/HCT/HCU/HCMOS Logic Family Specifications”.
Output capability: parallel outputs, bus driver; serial output, standard I
CC
category: MSI.
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.
GND = 0 V; t
r
= t
f
= 6 ns; C
