DESCRIPTION

The 74ABT2240 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed.

The 74ABT2240 device is an octal inverting buffer that is ideal for
driving bus lines. The device features two Output Enables (1OE

), each controlling four of the 3-State outputs.

2OE
The 74ABT2240 is designed with 30Ω series resistance in both the

High and Low states of the output. This design reduces line noise in
applications such as memory address drivers, clock drivers and bus
receivers/transmitters.

The 74ABT2240 is the same as the 74ABT240-1. The part number
has been changed to reflect industry standards.

NOTES:

1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability .

2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.

3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
