VCO section
GND = 0 V; tr =tf = 6 ns; CL = 50 pF
DC CHARACTERISTICS FOR 74HCT
Quiescent supply current
Voltages are referenced to GND (ground = 0 V)
Note
1. The value of additional quiescent supply current (
ICC) for a unit load of 1 is given above.
To determine
ICC per input, multiply this value by the unit load coefficient shown in the table below.
