74ABTH162827A

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.

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.
