74ABT240
Octal Buffer/Line Driver with 3-STATE Outputs
General Description
The ABT240 is an inverting octal buffer and line driver
designed to be employed as a memory address driver,
clock driver and bus oriented transmitter or receiver which
provides improved PC board density.
Features
s Output sink capability of 64 mA, source capability of
32 mA
s Guaranteed latchup protection
s High impedance glitch free bus loading during entire
power up and power down cycle
s Nondestructive hot insertion capability
