description

The ’ACT16863 are 18-bit noninverting

transceivers designed for asynchronous

communication between data buses. The

control-function implementation minimizes

external timing requirements.

The ’ACT16863 can be used as two 9-bit

transceivers or one 18-bit transceiver. They allow

data transmission from the A bus to the B bus or

from the B bus to the A bus, depending on the logic

level at the output-enable (OEAB or OEBA)

inputs.

The 74ACT16863 is packaged in TI’s shrink small-outline package (DL), which provides twice the I/O pin count

and functionality of standard small-outline packages in the same printed-circuit-board area.

The 54ACT16863 is characterized for operation over the full military temperature range of –55°C to 125°C. The

74ACT16863 is characterized for operation from –40°C to 85°C.
