The ’AC16620 are inverting 16-BIT TRANSCEIVERS designed for asynchronous communication between data BUSes. The control-function implementation allows for maximum flexibility in timing.
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 complementary 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 ’ACT16646 are 16-BIT BUS TRANSCEIVERS consisting of D-type flip-flops and control circuitry WITH 3-STATE OUTPUTS arranged for multiplexed transmission of data directly from the data BUS or from the internal storage registers. The devices can be used as two 8-bit TRANSCEIVERS or one 16-BIT transceiver. Data on the A or B BUS is clocked into the registers on the low-to-high transition of the appropriate clock (CLKAB or CLKBA) input. Figure 1 illustrates the four fundamental BUS management functions that can be performed WITH the BUS TRANSCEIVERS and registers.
The 54ACT16646 is characterized for operation over the full military temperature range of –55°C to 125°C. The 74ACT16646 is characterized for operation from –40°C to 85°C.

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 output-enable (1OE and 2OE) inputs can be used to disable the device so that the BUSes are effectively isolated.
