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 (nOE1, nOE2) for maximum
control flexibility.
The 74ABT162827A is designed with 30W 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.
