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 trans-

mitters/receivers.

The 25

Ω

series resistors in the outputs reduce ringing

and eliminate the need for external resistors.

power up and power down cycle
