54ACT16475 Description
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 either direction of data flow.
