Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150C. 3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed. 1998 Feb 19 758Philips Semiconductors Product specification 3.3V Quad buffer (3-State) 74LVT125 RECOMMENDED OPERATING CONDITIONS UMITS SYMBOL PARAMETER MIN MAX UNIT Vec DC supply voltage 2.7 3.6 Vv vi Input voltage 0 5.5 Vv Vin High-level input voltage 2.0 v Vit Low-level input voltage 0.8 v lon High-level output current -32 mA lo.
