74ABT2244 Octal Buffer/Line Driver with 25 Series Resistors in the Outputs
Features
Guaranteed latchup protection High-impedance, glitch-free bus loading during entire

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 transmitters/receivers. The 25 series resistors in the outputs reduce ringing and eliminate the need for external resistors.

power up and power down cycle
Nondestructive, hot-insertion capability
