Product data sheet Rev. 03 — 20 April 2005 6 of 19 Philips Semiconductors 74ABT544 Octal latched transceiver with dual enable; inverting; 3-state 8. Limiting values [1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed. [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. 9. Recommended operating conditions Table 5: Limiting values In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).
