Symbol VIK Vpass II ICC ICC Parameter input clamping voltage pass voltage input leakage current supply current additional supply current Conditions VCC = 4.5 V; II = -18 mA VI = VCC = 5.0 V; IO = -100 A VCC = 5.5 V; VI = GND or 5.5 V VCC = 5.5 V; IO = 0 mA; VI = VCC or GND control pins; per input; VCC = 5.5 V; one input at 3.4 V, other inputs at VCC or GND control pins; VI = 3 V or 0 V VO = 3 V or 0 V; OE = VCC VCC = 4.0 V VI = 2.4 V; II = 15 mA VCC = 4.5 V VI = 0 V; II = 64 mA VI = 0 V; II = 30 mA VI = 2.4 V; II = 15 mA
[1] [2] [3] All typical values are measured at VCC = 5 V; Tamb = 25 C. This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND. Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. ON resistance is determined by the lowest voltage of the two (A or B) terminals.

This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical ON resistance of the switch and a load capacitance, when driven by an ideal voltage source (zero output impedance). tPLH and tPHL are the same as tpd; tPZL and tPZH are the same as ten; tPLZ and tPHZ are the same as tdis.
