12-bit To 24-bit Registered Bus Exchanger With 3-state Outputs - Hitachi Semiconductor

The HD74ALVCH162270 is used in applications where 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 internal Registers on the low to high transition of the Clock (CLK) input when the appropriate CLKEN inputs are low. The select (SEL) line selects 1B or 2B data for the A outputs. For data transfer in the A to B direction, a two stage pipeline is provided in the A to 1B path, with a single storage Register in the A to 2B path. Proper control of the CLKENA inputs allows two sequential 12-bit words to be presented synchronously as a 24-bit word on the B port. Data flow is controlled by the active low output enables (OEA, OEB). The control terminals are registered to synchronize the bus direction changes with CLK. Active bus hold circuitry is provided to hold unused or floating data inputs at a valid Logic level. All outputs, which are designed to sink up to 12 mA, include 26 resistors to reduce overshoot and undershoot. By Renesas Technology
