Absolute Maximum Ratings(Note 1)
Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristic tables are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
Recommended Operating Conditions
Electrical Characteristics
over recommended free air temperature range. All typical values are measured at VCC = 5V, TA = 25°C.
Note 2: Plastic DIP package.
Note 3: n
= number of device outputs; n−1 outputs switching, each driven 0V to 3V one output @ GND.
Note 4: n
= number of device outputs; n outputs switching, n−1 inputs switching 0V to 3V. Input under test switching 3V to threshold (V
ILD); 0V to threshold
(VIHD); f = 1 MHz.
