GND = 0 V; Tamb = 25 °C; tr = tf ≤ 2.5 ns.

Symbol Parameter

Conditions

tPHL, tPLH propagation delay

CPAB, CPBA to An, Bn

CL = 50 pF; VCC = 3.3 V

fmax

maximum clock frequency CL = 50 pF; VCC = 3.3 V

CI

input capacitance

CI/O

input/output capacitance

CPD

power dissipation

outputs enabled;

capacitance per latch

VCC = 3.3 V

[1] 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.

[2] The condition is VI = GND to VCC.
