Frequently Asked Questions
What is the primary function of the SN74CBT16390DGGR?
The SN74CBT16390DGGR is a 16-bit to 32-bit FET bus multiplexer/demultiplexer that routes data between a 32-bit bus and two independent 16-bit buses. It enables dynamic bus width conversion with near-zero propagation delay, allowing a 32-bit data path to be shared by multiple 16-bit peripherals in a time-multiplexed fashion.
How many multiplexer channels does the SN74CBT16390DGGR have?
The SN74CBT16390DGGR provides 16 independent multiplexer/demultiplexer functions, with 16 inputs and 2 output groups. This configuration allows it to selectively route 16 data bits from either of two bus segments to a shared 32-bit bus, supporting flexible data path management in computing and embedded systems.
What package is the SN74CBT16390DGGR available in?
The SN74CBT16390DGGR is housed in a 56-pin SSOP (Shrink Small Outline Package) with a 0.635mm pitch, providing a compact surface-mount form factor for high pin count applications. The SSOP-56 package is well-suited for automated PCB assembly and is commonly used in dense digital logic board designs.
Is the SN74CBT16390DGGR bidirectional?
Yes, as a FET-based bus switch, the SN74CBT16390DGGR is inherently bidirectional. Current can flow in either direction through the MOSFET switch channels, making it suitable for both data read and write operations on the bus without needing direction control signals, simplifying the system interface design.
