Detailed Design Procedure
Recommended Input Conditions:
For rise time and fall time specifications, see Δt/ΔV in the
Recommended Operating Conditions
table.
For specified high and low levels, see V
IH
and V
IL
in the
Recommended Operating Conditions
table.
Inputs are overvoltage tolerant allowing them to go as high as 5.5 V at any valid V
CC.
Recommended Output Conditions:
Load currents should not exceed 25 mA per output and 75 mA total for the part.
Outputs should not be pulled above V
CC.
