The 74ACT16470 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 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.

To avoid false clocking of the flip-flops, CE should not be switched from high to low while CLK is high.

The 74ACT16470 is packaged in TI's shrink small-outline package, which provides twice the I/O pin count and functionality of standard small-outline packages in the same printed-circuit-board area.

The 74ACT16470 is characterized for operation over the full military temperature range of 55°C to 125°C. The 74ACT16470 is characterized for operation from 40°C to 85°C.
