The 74AHC/AHCT541 are octal non-inverting buffer/line drivers with 3-state bus compatible outputs. The 3-state outputs are controlled by the output enable inputs OE0 and OE1. A HIGH on OEn causes the outputs to assume a high-impedance OFF-state. TYPICAL SYMBOL tPHL/tPLH CI CO CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in µW). PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; ∑ (CL × VCC2 × fo) = sum of outputs; CL = output load capacitance in pF; VCC = supply voltage in Volts. 2. The condition is VI = GND to VCC. PARAMETER propagation delay An to Yn input capacitance output capacitanc...
