74AC16640 16-BIT BUS TRANSCEIVERS

The ’AC16640 are inverting 16-bit transceivers designed for asynchronous communication between data buses. These devices can be used as two 8-bit transceivers or one 16-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 direction-control (1DIR and 2DIR) inputs. The out.

Features

E) inputs can be used to disable the device so that the buses are effectively isolated. 54AC16640 . . . WD PACKAGE 74AC16640 . . .
