5 / 10 page 5 www.fairchildsemi.com DC Electrical Characteristics for ACTQ (Continued) Note 11: Max number of outputs defined as (n). Data Inputs are driven 0V to 3V. One output @ GND. Note 12: Max number of Data Inputs (n) switching. (n −1) Inputs switching 0V to 3V (ACTQ). Input-under-test switching: 3V to threshold (V ILD), 0V to threshold (VIHD), f = 1 MHz. AC Electrical Characteristics for ACQ Note 13: Voltage Range 5.0 is 5.0V ± 0.5V. Voltage Range 3.3 is 3.3V ± 0.3V. Note 14: Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The specification applies to any outputs switching in the same direction, either HIGH to LOW (tOSHL) or LOW to HIGH (tOSLH). Parameter guaranteed by design.
