74ACT16861
description
The ’ACT16861 are noninverting 20-bit transceivers designed for asynchronous munication 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.
