DC Electrical Characteristics for ACTQ

Notes:

7. All outputs loaded; thresholds on input associated with output under test.

8. Maximum test duration 2.0ms, one output loaded at a time.

9. Max number of outputs defined as (n). n–1 Data Inputs are driven 0V to 3V; one output @ GND.

10. Max number of Data Inputs (n) switching. (n–1) Inputs switching 0V to 3V (ACTQ). Input-under-test switching:

3V to threshold (VILD), 0V to threshold (VIHD) f = 1 MHz.
