FEATURES

data/address paths or buses carrying parity

required with MOS microprocessors

and 200 V per Machine Model

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.
