Octal bus transceiver; 3-state
7. Limiting values
[1] The minimum input voltage ratings may be exceeded if the input current ratings are observed.
[2] The output voltage ratings may be exceeded if the output current ratings are observed.
[3] When V
CC
= 0 V (Power-down mode), the output voltage can be 3.6 V in normal operation.
