Dual supply translating transceiver; 3-state
[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 = load capacitance in pF;
VCC = supply voltage in V;
N = number of inputs switching;
Σ(C
L × VCC
2
× f
o) = sum of the outputs.
[2]
fi = 10 MHz; VI = GND to VCC; tr = tf = 1 ns; CL = 0 pF; RL = ∞ Ω.
Table 11.
Typical power dissipation capacitance at VCC(A) = VCC(B) and Tamb = 25 °C [1][2]
Voltages are referenced to GND (ground = 0 V).
