74ABT2244 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 25Ω series resistors in the outputs reduce ringing and eliminate the need for external resistors.
