POWER SUPPLY CHARACTERISTICS
Symbol Parameter Test Conditions(1) Max. Unit
ICCQ Quiescent Power Supply Current VCC = Max., VIN = GND or Vcc, f = 0 1.5 mA
∆ICC Power Supply Current per Control Input HIGH (2) VCC = Max., VIN = 3.4V, f = 0 2.5 mA
ICCD Dynamic Power Supply Current per MHz(3) VCC = Max., A and B pins open
Control Input Toggling at 50% Duty Cycle 0.25 mA/MHz
NOTES:
1. For conditi ons shown as Min. or M ax., use the appropri ate values specified under DC Electrical Characteristic s.
2. Per TLL driven i nput (VIN = 3.4V, control inputs only). A, B, C, and D pins do not c ontribute to ∆Icc.
3. This current applies to the control inputs only and repres ents the current required to switch i nternal capacitanc e at the speci fied frequency. The A
and B inputs generate no significant AC or DC currents as they transition. This parameter is guarant eed but not production t ested.

2. This param et er i s guaranteed but not produc t i on tested.
3. The time constant for the switc h al one i s of the order of 0.25ns for CL = 50pF. The bus switch contribut es no propagation delay ot her than the RC
delay of t he ON resistance of the switc h and the load capacit ance. Since t hi s time cons tant is muc h smaller than the ri se and fall times of typical
driving s i gnal s, it adds v ery little propagation delay to t he system. Propagation delay of the bus swit ch, when used in a system, is determined by the
driving c i rcuit on the driv i ng s i de of the switc h and i ts interaction with the load on t he dri ven side.
