The SN74ALVCH16282 is an 18-bit to 36-bit registered bus exchanger designed for 2.3-V to 3.6-V VCC operation.
This part is intended for use in applications in which data must be transferred from a narrow high-speed bus to a wide lower-frequency bus. It is designed specifically for low-voltage (3.3-V) VCC operation.
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. For data transfer in the B-to-A direction, the select (SEL\) input 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 1B path, with a single storage register in the 2B path. Data flow is controlled by the active-low output enable (OE\) \and the DIR input. The DIR control pin is registered to synchronize the bus direction changes with the clock.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN74ALVCH16282 is characterized for operation from -40°C to 85°C.
