description
This octal buffer and line driver is designed
specifically to improve both the performance and
density of 3-state memory address drivers, clock
drivers, and bus-oriented receivers and
transmitters.
The 25-resistors in the lower output circuit
reduce ringing and eliminate the need for external
resistors.
The SN74F2244 is characterized for operation
from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input voltage ratings may be exceeded if the input current ratings are observed.
