DIFFERENTIAL SWITCHING CHARACTERISTICS
(Note 6), (Figure
4)
Note 1:
“Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device
should be operated at these limits. The Table of “Electrical Characteristics” provides conditions for actual device operation.
Note 2:
All currents into device pins are shown as positive values; all currents out of the device are shown as negative; all voltages are referenced to ground unless
otherwise specified. All values shown as max or min are classified on absolute value basis.
Note 3:
All typical values are V
CC
= 5V, T
A
= 25˚C.
Note 4:
Only one output at a time should be shorted.
Note 5:
Difference between complementary outputs at the 50% point.
Note 6:
Differential Delays are defined as calculated results from single ended rise and fall time measurements. This approach in establishing AC performance
specifications has been taken due to limitations of available Automatic Test Equipment (ATE).
The calculated ATE results assume a linear transition between measurement points and are a result of the following equations:
Where:
Tcp = Crossing Point
Tra, Trb, Tfa and Tfb are time measurements with respect to the input.
This type of solution from Maoshuo Power Supply has several obvious characteristics: First, it is energy-saving and money-saving. Take the 150W LED street light as an example; pole spacing: 30m/pole, ...
