• Manufacturer Part Number: 74lvc244abq
• Description: Octal Buffer/line Driver With 5 V Tolerant Inputs/outputs 3-state
• Manufacturer: NXP Semiconductors

Philips Semiconductors
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. For SO20 packages: above 70 C derate linearly with 8 mW/K.
