Dual bus buffer/line driver; 3-state

11. Dynamic characteristics

[1]

Typical values are measured at nominal VCC and at Tamb = 25 °C.

[2]

tpd is the same as tPLH and tPHL.

[3]

ten is the same as tPZH and tPZL.

[4]

tdis is the same as tPLZ and tPHZ.

[5]

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 = number of inputs switching;

Σ(C

L × VCC

2

× f

o) = sum of outputs.

Dynamic characteristics

Voltages are referenced to GND (ground 0 V); for test circuit see Figure 9.
