2 / 6 page www.fairchildsemi.com 2 Absolute Maximum Ratings(Note 1) Recommended Operating Conditions (Note 2) 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 Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation. Note 2: Unused inputs must be held HIGH or LOW. They may not float. DC Electrical Characteristics Note 3: All outputs loaded thresholds on input associated with output under test. Note 4: Maximum test duration 2.0 ms, one output loaded at a time. Note 5: Incident wave switching on transmission lines with impedances as low as 75 Ω for commercial temperature range is guaranteed for 74LVQ. Note 6: Worst case package. Note 7: Max number of outputs defined as (n). Data inputs are driven 0V to 3.3V; one output at GND. Note 8: Max number of Data Inputs (n) switching. (n − 1) inputs switching 0V to 3.3V. Input-under-test switching: 3.3V to threshold (V ILD), 0V to threshold (VIHD), f = 1 MHz.
