Octal bus transceiver/register; 3-state

7.

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. The maximum junction temperature of this integrated circuit should not exceed 150

°C.
