Measured by the voltage drop between A and B pins at the indicated current through the switch. AC ELECTRICAL CHARACTERISTICS Limits TA = −40_C to )85_C VCC = 4.5 to 5.5 V VCC = 4.0 V Symbol Parameter Conditions Figures Min Max Min Max Unit tPHL, tPLH Prop Delay Bus to Bus (Note 7) VI = OPEN 3 and 4 0.25 0.25 ns tPZH, tPZL Output Enable Time VI = 7 V for tPZL VI = OPEN for tPZH 3 and 4 1.5 5.9 6.4 ns tPHZ, tPLZ Output Disable Time VI = 7 V for tPLZ VI = OPEN for tPHZ 3 and 4 1.5 6.0 5.7 ns 7. 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 50 pF load capacitance, when driven by an ideal voltage source (zero output impedance).
