74ABT2240
Octal Buffer/Line Driver with
25Ω Series Resistors in the Outputs
General Description
The ABT2240 is an inverting 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.
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
