Product specification

Octal buffer/line driver with 5 V tolerant

inputs/outputs (3-state)

74LVC244A; 74LVCH244A

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.

a) For SSOP20 and TSSOP20 packages: above 60

°C derate linearly with 5.5 mW/K.

b) For DHVQFN20 packages: above 60

°C derate linearly with 5.5 mW/K.
