DC CHARACTERISTICS FOR 74HCT

For the DC characteristics see “74HC/HCT/HCU/HCMOS Logic Family Specifications”, except that VOH and VOL are not

valid for driver output.

They are replaced by the values given below.

Output capability: driver 8 mA.

ICC category: LSI.

Voltages are referenced to GND (ground = 0 V).

Notes to the HCT DC Characteristics

1. The value of additional quiescent supply current (∆ICC) for a unit load of 1 is given in the family specifications.

2. To determine ∆ICC per input, multiply this value by the unit load coefficient shown in the table below.
