description

The 'ACT16475 are 18-bit registered transceivers that contain twosets of D-type flip-flops for temporary storage of data flowing ineither direction. They can be used as two 9-bit transceivers or one18-bit transceiver. Separate clock (CLKAB and CLKBA) andoutput-enable (or) inputs are provided for eachregister to permit independent control in either direction of dataflow.

Data at the A inputs meeting the setup time requirements istransferred to the B outputs on the positive-going edge of CLKAB.Withlow, the3-state B outputs are enabled and reflect the inverted A data. Dataflow from B to A is similar but requires the use of the CLKBA andinputs.

The 74ACT16475 is packaged in TI's shrink small-outline package,which provides twice the I/O pin count and functionality of standardsmall-outline packages in the same printed-circuit-board area.

The 54ACT16475 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. The74ACT16475 is characterized for operation from -40°C to85°C.

A-to-B data flow is shown: B-to-A flow is similar but usesCLKBA and OEBA\.
