Frequently Asked Questions
What is the bandwidth of the SN74CBT16292DGGR?
The SN74CBT16292DGGR supports a 200MHz nominal bandwidth per channel, enabling reliable switching and routing of high-speed digital signals including DDR memory address lines, PCIe reference signals, and high-frequency bus data without significant signal degradation or bandwidth limitation.
What is the on-state resistance of the SN74CBT16292DGGR and why does it matter?
The SN74CBT16292DGGR has a maximum on-state resistance of 20 ohms per FET switch channel. Lower on-resistance minimizes signal attenuation, voltage drop, and power dissipation in the switch, which is critical for maintaining signal integrity in high-speed bus switching and multiplexing applications.
How many channels does the SN74CBT16292DGGR provide and what is the switching topology?
The SN74CBT16292DGGR provides 12 independent SPDT (single-pole double-throw) FET switch channels, each capable of routing one signal to one of two outputs. The bidirectional FET topology allows signals to pass in either direction, making it suitable for both multiplexing inputs and demultiplexing outputs.
What is the function of the internal pulldown resistors in the SN74CBT16292DGGR?
The internal pulldown resistors in the SN74CBT16292DGGR hold signal lines at a defined low level when the switch channels are in the off state or when no active driver is connected. This prevents floating inputs from causing unpredictable states in downstream logic, improving system reliability without requiring external resistors.
