Detailed Design Procedure
Recommended input conditions:
Rise time and fall time specs: See (Δt/ΔV) in the
Recommended Operating Conditions
table.
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
Recommend output conditions:
Load currents should not exceed 25 mA per output and 50 mA total for the part
Outputs should not be pulled above V
CC
