DESCRIPTION
The 74ABT861 bus transceiver provides high performance bus
interface buffering for wide data/address paths of buses carrying
parity.
The 74ABT861 10-bit bus transceiver has NOR-ed transmit and
receive output enables for maximum control flexibility.

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.
