This 12-bit to 24-bit registered bus exchanger

designed for 1.65-V to 3.6-V V

CC operation.

The SN74ALVCH162268 is used for applications

which data must be transferred from a narrow

high-speed bus to a wide, lower-frequency bus.

The device provides synchronous data exchange

between the two ports. Data is stored in the inte

registers on the low-to-high transition of the

(CLK) input when the appropriate clock-enable

( CLKEN) inputs are low. The select ( SEL) line

synchronous with CLK and selects 1B or 2B

data for the A outputs.

For data transfer in the A-to-B direction, a two-st

storage register in the A-to-2B path. Proper c

presented synchronously as a 24-bit word on

( OEA, OEB). These control terminals are registere

The B outputs, which are designed to sink up

and undershoot.
