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.
