Product specification
Octal buffer/line driver; 3-state
74AHC541; 74AHCT541
RECOMMENDED OPERATING CONDITIONS
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134); voltages are referenced to GND (ground = 0 V).
Notes
1.
2.
The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
For SO-package: above 70
°
C the value of P
D
derates linearly with 8 mW/K.
For TSSOP-package: above 60
°
C the value of P
D
derates linearly with 5.5 mW/K.
