Product specification
Octal transceiver with direction pin, 30
series
termination resistors; 5 V tolerant input/output; 3-state
74LVC2245A
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.
2.
The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
For SO20 packages: above 70
°
C derate linearly with 8 mW/K.
For SSOP20 and 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.
