74LVC541A
Octal buffer/line driver with 5 V tolerant inputs/outputs; 3-state
6. Functional description
[1] H = HIGH voltage level
L = LOW voltage level
X = don’t care
Z = high-impedance OFF-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] 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.
For DHVQFN20 packages: above 60 C the value of P
tot
derates linearly with 4.5 mW/K.
