74HC27; 74HCT27

Triple 3-input NOR gate

[1]

tpd is the same as tPHL and tPLH.

[2]

tt is the same as tTHL and tTLH.

[3]

CPD is used to determine the dynamic power dissipation (PD in µW):

PD =CPD × VCC2 × fi × N+ ∑ (CL × VCC2 × fo) where:

fi = input frequency in MHz;

fo = output frequency in MHz;

CL = output load capacitance in pF;

VCC = supply voltage in V;

N = number of inputs switching;

∑ (C

L × VCC
