DC Electrical Characteristics

SOIC package.

Notes:

3. Max number of outputs defined as (n). n-1 data inputs are driven 0V to 3V. One output at LOW. Guaranteed, but not

tested.

4. Max number of data inputs (n) switching. n-1 inputs switching 0V to 3V. Input-under-test switching: 3V to threshold

(VILD), 0V to threshold (VIHD). Guaranteed, but not tested.

5. Max number of outputs defined as (n). n – 1 data inputs are driven 0V to 3V. One output HIGH. Guaranteed, but not

tested.
