Philips Semiconductors Product specification
Octal buffer/line driver; 3-state 74ALVC244
RECOMMENDED OPERATING CONDITIONS
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134); voltages are referenced to GND (ground = 0 V).
Notes
1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. When V
CC
= 0 V (Power-down mode), the output voltage can be 3.6 V in normal operation.
3. For SO20 packages: above 70 °C derate linearly with 8 mW/K.
For TSSOP20 packages: above 60 °C derate linearly with 5.5 mW/K.
For DHVQFN20 packages: above 60 °C derate linearly with 4.5 mW/K.
