GND = 0 V; for test circuit see Figure 6.
Symbol Parameter
Conditions
Tamb = −40 °C to +125 °C
tPHL, tPLH propagation delay input
nA to output nY
see Figure 5
VCC = 1.65 V to 1.95 V
VCC = 2.3 V to 2.7 V
VCC = 2.7 V
VCC = 3.0 V to 3.6 V
VCC = 4.5 V to 5.5 V
[1] All typical values are measured at nominal VCC and Tamb = 25 °C.
[2] CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + Σ(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 = total load switching outputs;
Σ(CL × VCC2 × fo) = sum of the outputs.
[3] The condition is VI = GND to VCC.
