1-of-2 decoder/demultiplexer

11. Dynamic characteristics

[1]

Typical values are measured at Tamb =25 °C and VCC = 1.8 V, 2.5 V, 2.7 V, 3.3 V and 5.0 V respectively.

[2]

tpd is the same as tPLH and tPHL.

[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

× f

o) = sum of outputs.

Dynamic characteristics

Voltages are referenced to GND (ground = 0 V). For test circuit see Figure 6.
