DC Electrical Characteristics

Notes:

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

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

3. IIN and ICC @ 3.0V are guaranteed to be less than or equal to the respective limit @ 5.5V VCC.

4. Max number of outputs defined as (n). Data Inputs are driven 0V to 5V. One output @ GND.

5. Max number of Data Inputs (n) switching. n–1 Inputs switching 0V to 5V. Input-under-test switching: 5V to threshold

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