4 / 14 page ©1995 Fairchild Semiconductor Corporation www.fairchildsemi.com 74LCX540 Rev. 1.1 4 DC Electrical Characteristics AC Electrical Characteristics Notes: 6. Outputs disabled or 3-STATE only. 7. 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). Symbol Parameter Conditions VCC (V) TA = −40°C to +85°C Units Min. Max.
