54ACT16470 16-BIT REGISTERED TRANSCEIVERS

The ’ACT16470 are 16-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 8-bit transceivers or one 16-bit transceiver. Separate clock (CLKAB or CLKBA) and output-enable (OEAB or OEBA) inputs are provided for each register to permit independent control in eit.

Features

t control in either direction of data flow. The A-to-B enable (CEAB) input must be low to enter data from A or to output data to B. If both CEAB and CLKAB are low, then B port will have the level of A port prior to the most recent low-to-high transition of CLKAB. Data flow from B to A is similar, but requires the use of CEBA, CLKBA, and OEBA inputs. 54ACT16470 . . . WD PACKAGE 74ACT16470 . . .
