Product data sheet Rev. 01 — 26 February 2004 11 of 22 Philips Semiconductors 74LVC1G384 Bilateral switch [1] All typical values are measured at Tamb =25 °C. [2] tPHL and tPLH propagation delay is the calculated RC time constant of the typical switch ON-resistance of the switch and the specified capacitance when driven by an ideal voltage source (zero output impedance). [3] CPD is used to determine the dynamic power dissipation (PD in µW). PD =CPD × VCC2 × fi +(CL +CS)× VCC2 × fo where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; CS = maximum switch capacitance in pF; VCC = supply voltage in V. [4] The condition is VI = GND to VCC. 13. Waveforms tPHZ, tPLZ turn-off time E to Y or Z see Figure 11 VCC = 1.65 V to 1.95 V 1.0 - 13.0 ns VCC = 2.3 V to 2.7 V 1.0 - 9.0 ns VCC = 2.7 V 1.0 - 9.5 ns VCC = 3.0 V to 3.6 V 1.0 - 8.5 ns VCC = 4.5 V to 5.5 V 1.0 - 6.5 ns Table 9: Dynamic characteristics …continued At recommended operating conditions; voltages are referenced to GND (ground = 0 V); test circuit Figure 12.
