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.
