74ABT2244
Octal Buffer/Line Driver with
25Series Resistors in the Outputs
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 transmit-
ters/receivers.
The 25series resistors in the outputs reduce ringing and
eliminate the need for external resistors.
Features
s Guaranteed latchup protection
s High impedance glitch-free bus loading during entire
power up and power down cycle
s Nondestructive hot insertion capability
