74HC/HCT7403
DC CHARACTERISTICS FOR 74HCT
For the DC characteristics see “74HC/HCT/HCU/HCMOS Logic Family Specifications”, except that V_OH and V_OL are not
valid for driver output.
They are replaced by the values given below.
Output capability: driver 8 mA.
I_CC category: LSI.
Voltages are referenced to GND (ground = 0 V).

Notes to the HCT DC Characteristics
1. The value of additional quiescent supply current (∆I_CC) for a unit load of 1 is given in the family specifications.
2. To determine ∆I_CC per input, multiply this value by the unit load coefficient shown in the table below.
