74ABT2244 Rev. 1.4

74ABT2244

Octal Buffer/Line Driver with 25

Ω Series Resistors

in the Outputs

Features

power up and power down cycle

General Description

The ABT2244 is an octal buffer and line driver designed

to drive the capacitive inputs of MOS memory drivers,

address drivers, clock drivers, and bus-oriented trans-

mitters/receivers.

The 25

Ω series resistors in the outputs reduce ringing

and eliminate the need for external resistors.

Ordering Information

Devices are also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering number.

Pb-Free package per JEDEC J-STD-020B.
