Product data sheet Rev. 03 — 11 May 2004 2 of 20 Philips Semiconductors 74LVC821A 10-bit D-type flip-flop with 5 V tolerant inputs/outputs 3. Quick reference data [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 = output load capacitance in pF; VCC = supply voltage in Volts; N = total load switching outputs; Σ (C L × VCC 2 × f o) = sum of the outputs. [2] The condition is VI = GND to VCC. 4. Ordering information Table 1: Quick reference data GND = 0 V; Tamb = 25 °C; tr = tf ≤ 2.5 ns.
