Product data sheet Rev. 11 — 1 March 2012 6 of 18 NXP Semiconductors 74LVT16244B; 74LVTH16244B 3.3 V 16-bit buffer/driver; 3-state [1] The input and output negative voltage ratings may be exceeded if the input and output clamp 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. [3] Above 60 C the value of P tot derates linearly with 5.5 mW/K. [4] Above 70 C the value of P tot derates linearly with 1.8 mW/K. 8. Recommended operating conditions IO output current output in LOW-state - 128 mA output in HIGH-state 64 - mA Tstg storage temperature 65 +150 C Tj junction temperature [2] - 150 C Ptot total power dissipation Tamb = 40 C to +85 C; (T)SSOP48 package [3] - 500 mW VFBGA56 package [4] - 1000 mW HXQFN60 package [4] - 1000 mW Table 4.
