Units ICC Quiescent Power VCC = Max., PI3B3384 — 0.1 3 µA Supply Current VIN = GND or VCC PI3B32384 ∆ICC Supply Current per VCC = Max., VIN = 3.0V(3) — — 750 µA Input @ TTL HIGH PI3B3384 Switching Characteristics Over Operating Range Notes: 1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device. 2. Typical values are at VCC = 3.3V, +25°C ambient. 3. Per TTL driven input (control inputs only); A and B pins do not contribute to ICC. Notes: 1. See test circuit and waveforms. 2. This parameter is guaranteed but not tested on Propagation Delays. 3. The bus switch contributes no propagational delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side. s r e t e m a r a Pn o i t p i r c s e Ds n o i t i d n o C ( ) 3 4 8 3 3 B 3 I P s t i n U . m o C . n i M. x a M t H L P t L H P y a l e D n o it a g a p o r P ) 3 , 2 ( x A o t x B , x B o t x A CL F p 0 5 = RL 0 0 5 = Ω 5 2 . 0 s n t H Z P t L Z P e m i T e l b a n E s u B x B r o x A o t x E B CL F p 0 5 = RL 0 0 5 = Ω RL 0 0 5 = Ω 0 . 10 . 4 t Z H P t Z L P e m i T e l b a s i D s u B x B r o x A o t x E B 0 . 15 . 3 PI3B32384 Com.
