DESCRIPTION
The 74ABT162827A high-performance BiCMOS device combines
low static and dynamic power dissipation with high speed and high
output drive.
The 74ABT162827A 20-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.
The 74ABT162827A is designed with 30 series resistance in both
the pull–up and pull–down output structures. This design reduces
line noise in applications such as memory address drivers, clock
drivers and bus receivers/transmitters.
Two options are available, 74ABT162827A which does not have the
bus-hold feature and 74ABTH162827A which incorporates the
bus-hold feature.

Storage temperature range –65 to 150 °C
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.
