DC Electrical Characteristics for ACQ
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 (ACQ). Input-under-test switching:
5V to threshold (VILD), 0V to threshold (VIHD), f = 1MHz.
