DESCRIPTION

The74ABT16825A high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.

The74ABT16825A 18-bit buffers provide high performance bus
interface buffering for wide data/address paths or buses carrying
parity. They have NOR Output Enables (nOE
control flexibility.

Two options are available, 74ABT16825A which does not have the
bus-hold feature and 74ABTH16825A which incorporates the
bus-hold feature.

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.
