74HC/HCT595
DC CHARACTERISTICS FOR 74HCT
For the DC characteristics see chapter “74HC/HCT/HCU/HCMOS Logic Family Specifications”.
Output capability: parallel outputs, bus driver; serial output, 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.
GND = 0 V; tr = tf = 6 ns; CL = 50 pF.
