Octal Buffer/Line Driver with Series Resistors in the Outputs

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