Features
■ Guaranteed latchup protection
■ High-impedance, glitch-free bus loading during entire
power up and power down cycle
■ Nondestructive, hot-insertion capability
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 25Ω series resistors in the outputs reduce ringing
and eliminate the need for external resistors.
