This parameter is guaranteed but not tested on Propagation Delays. 2. 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. 3.

For example, given a +3.3V supply, IN may be driven LOW to 0V and HIGH to 3.6V. Driving IN Rail-toRail minimizes power consumption. 72 CPU 128M DIMM 100 MHz Power-Supply Sequencing and Hot Plug Information Proper power-supply sequencing is advised for all CMOS devices. It is recommended to always apply VCC and GND before applying signals to the input/output or control pins.
