Dynamic characteristics [1] Typical values are measured at Tamb =25 °C and nominal VCC. [2] tpd is the same as tPLH and tPHL. [3] Propagation delay is the calculated RC time constant of the typical ON resistance of the switch and the specified capacitance when driven by an ideal voltage source (zero output impedance). [4] ten is the same as tPZH and tPZL. [5] tdis is the same as tPLZ and tPHZ. Table 9. Dynamic characteristics At recommended operating conditions; voltages are referenced to GND (ground = 0 V); for load circuit see Figure 18.
