74AC240 74ACT240
Octal Buffer/Line Driver with 3-STATE Outputs
General Description
The AC/ACT240 is an 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 ICC and IOZ reduced by 50%
s Inverting 3-STATE outputs drive bus lines or buffer
memory address registers
s Outputs source/sink 24 mA
s ACT240 has TTL-compatible inputs

Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, with-
out exception, to ensure that the system design is reliable over its power
supply, temperature, and output/input loading variables. Fairchild does not
recommend operation of FACTcircuits outside databook specifications.
