(Note 1) Max Unit “H” level VIH ⎯ 4.5~5.5 2.0 ⎯ ⎯ Input voltage “L” level VIL ⎯ 4.5~5.5 ⎯ ⎯ 0.8 V Input leakage current ( OE , S) IIN VIN = 0~5.5 V 4.5~5.5 ⎯ ⎯ ±1.0 μA Power off leakage current IOFF A, B, OE = 0~5.5 V 0 ⎯ ⎯ ±1.0 μA Off-state leakage current (switch off) ISZ A, B = 0~5.5 V, OE = VCC 4.5~5.5 ⎯ ⎯ ±1.0 μA IIS = 64 mA 4.5 ⎯ 5 7 VIS = 0 V IIS = 30 mA 4.5 ⎯ 5 7 ON resistance (Note 2) RON VIS = 2.4 V, IIS = 15 mA 4.5 ⎯ 10 15 Ω ICC VIN = VCC or GND, IOUT = 0 5.5 ⎯ ⎯ 10 μA Increase in ICC per input ΔICC VIN = 3.4 V (one input) 5.5 ⎯ ⎯ 2.5 mA Note 1: Typical values are at VCC = 5 V, Ta = 25°C. Note 2: Measured by the voltage drop between A and B pins at the indicated current through the switch. ON resistance is determined by the lower of the voltages on the two (A or B) pins. AC Characteristics (Ta = −40~85°C) Characteristics Symbol Test Condition VCC (V) Min Max Unit Propagation delay time (bus to bus) tpLH tpHL Figure 1, Figure 2 (Note) 4.5 ⎯ 0.25 ns Propagation delay time (S to bus) tpLH tpHL Figure 1, Figure 2 4.5 ⎯ 6.0 ns Output enable time ( OE to bus) tpZL tpZH Figure 1, Figure 3 4.5 ⎯ 5.6 ns Output enable time (S to bus) tpZL tpZH Figure 1, Figure 3 4.5 ⎯ 5.6 ns Output disable time ( OE to bus) tpLZ tpHZ Figure 1, Figure 3 4.5 ⎯ 6.4 ns Output disable time (S to bus) tpLZ tpHZ Figure 1, Figure 3 4.5 ⎯ 6.4 ns Note: 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 the source (zero output impedance). Capacitive Characteristics (Ta = 25°C) Characteristics Symbol Test Condition VCC (V) Typ.
