2 / 7 page www.fairchildsemi.com 2 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.
