6 / 12 page ©1989 Fairchild Semiconductor Corporation www.fairchildsemi.com 74ACQ374, 74ACTQ374 Rev. 1.3 6 AC Electrical Characteristics for ACQ Notes: 10. Voltage range 5.0 is 5.0V ± 0.5V. Voltage range 3.3 is 3.3V ± 0.3V. 11. 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.
