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 150°C. 3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed. 1998 Oct 07 3 Philips Semiconductors Product specification 2.5V/3.3V 16-bit buffer/driver (3-State) 74ALVT16244 RECOMMENDED OPERATING CONDITIONS SYMBOL VCC VI VIH VIL IOH IOL ∆t/∆v Tamb DC supply voltage Input voltage High-level input voltage Input voltage High-level output current Low-level output current Low-level output current; current duty cycle ≤ 50%; f ≥ 1kHz Input transition rise or fall rate; Outputs enabled Operating free-air temperatur.
