Product data sheet Rev. 05 — 25 August 2009 7 of 17 NXP Semiconductors 74LVC245A; 74LVCH245A Octal bus transceiver; 3-state [1] tpd is the same as tPLH and tPHL. ten is the same as tPZL and tPZH. tdis is the same as tPLZ and tPHZ. [2] Typical values are measured at Tamb =25 °C. [3] Typical values are measured at Tamb =25 °C and VCC = 3.3 V. [4] Skew between any two outputs of the same package switching in the same direction. This parameter is guaranteed by design. [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 Volts N = number of inputs switching Σ(C L × VCC 2 × f o) = sum of the outputs. 11.
