3 / 8 page 3 PS2011E 06/20/06 PI74FCT244T/2244T PI74FCT541T/2541T Octal Buffer/Line Drivers Maximum Ratings (Above which the useful life may be impaired. For user guidelines, not tested.) Note: Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other con- ditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. DC Electrical Characteristics (Over the Operating Range, TA = –40°C to +85°C, VCC = 5.0V ± 5%) Parameters Description Test Conditions(1) Min. Typ(2) Max.
