54ACT16475 18-BIT REGISTERED TRANSCEIVERS

The ’ACT16475 are 18-bit registered transceivers that contain two sets of D-type flip-flops for temporary storage of data flowing in either direction. They can be used as two 9-bit transceivers or one 18-bit transceiver. Separate clock (CLKAB and CLKBA) and output-enable (OEAB or OEBA) inputs are provided for each register to permit independent control in ei.

Features

gister to permit independent control in either direction of data flow. Data at the A inputs meeting the setup time requirements is transferred to the B outputs on the positive-going edge of CLKAB. With OEAB low, the 3-state B outputs are enabled and reflect the inverted A data. Data flow from B to A is similar but requires the use of the CLKBA and OEBA inputs. 54ACT16475 . . .
