74AC240, 74ACT240
Octal Buffer/Line Driver with 3-STATE Outputs
General Description
Features
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.
■ I and I reduced by 50%
CC OZ
■ Inverting 3-STATE outputs drive bus lines or buffer
memory address registers
■ Outputs source/sink 24mA
■ ACT240 has TTL-compatible inputs

Absolute Maximum Ratings
The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed.
The device should not be operated at these limits.The parametric values defined in the Electrical Characteristics tables
are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the
conditions for actual device operation.
