description
The ’ACT16861 are noninverting 20-bit
transceivers designed for asynchronous
communication between data buses. The
control-function implementation minimizes
external timing requirements.
The ’ACT16861 can be used as two 10-bit
transceivers or one 20-bit transceiver. They allow
data transmission from the A bus to the B bus or
from the B bus to the A bus, depending upon the
logic level at the output-enable (OEAB or OEBA)
inputs. The output-enable inputs can be used to
disable the device so that the buses are effectively
isolated.
The 74ACT16861 is packaged in TI’s shrink small-outline package, which provides twice the I/O pin count and
functionality of standard small-outline packages in the same printed-circuit-board area.
The 54ACT16861 is characterized for operation over the full military temperature range of –55°C to 125°C. The
74ACT16861 is characterized for operation from –40°C to 85°C.
