Octal bus transceiver; 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] For DIP20 packages: above 70 °C the value of P
tot
derates linearly with 12 mW/K.
For SO20 packages: above 70 °C the value of P
tot
derates linearly with 8 mW/K.
For (T)SSOP20 packages: above 60 °C the value of P
tot
derates linearly with 5.5 mW/K.
8. Recommended operating conditions
[1] The static characteristics are guaranteed from V
CC
= 1.2 V to V
CC
= 5.5 V, but LV devices are guaranteed to function down to
V
CC
= 1.0 V (with input levels GND or V
CC
).
Table 4. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).
