Notes: test circuit waveforms. This parameter guaranteed tested Propagation Delays. switch contributes propagational delay other than delay resistance switch load capacitance. time constant switch alone order 0.25ns 50pF load. Since this time constant much smaller than rise/fall times typical driving signals, adds very little propagational delay system. Propagational delay switch when used system determined driving circuit driving side switch interaction with load driven side.
Applications Information
Logic Inputs
logic control inputs driven +3.6V regardless supply voltage. example, given +3.3V supply, driven high 3.6V. Driving Rail-to-Rail® minimizes power consumption.
Power-Supply Sequencing Plug Information
Proper power-supply sequencing recommended CMOS devices. Always apply before applying signals input/output control pins.
