Product speciﬁcation

Dual 4-input AND gate

74HC/HCT21

DC CHARACTERISTICS FOR 74HCT

For the DC characteristics see

“74HC/HCT/HCU/HCMOS Logic Family Specifications”.

Output capability: standard

ICC category: SSI

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.

AC CHARACTERISTICS FOR 74HCT

GND = 0 V; tr =tf = 6 ns; CL = 50 pF
