3 / 5 page 3 www.fairchildsemi.com AC Electrical Characteristics Note 6: This parameter is guaranteed by design but is not tested. The bus switch contributes no propagation delay other than the RC delay of the typical On resistance of the switch and the 50pF load capacitance, when driven by an ideal voltage the source (zero output impedance). Capacitance (Note 7) Note 7: TA = +25°C, f = 1 MHz, Capacitance is characterized but not tested. AC Loading and Waveforms Note: Input driven by 50 Ω source terminated in 50 Ω Note: CL includes load and stray capacitance Note: Input PRR = 1.0 MHz, t W = 500 ns FIGURE 1. AC Test Circuit FIGURE 2.
