This device offers very fast switching speeds, accuracy, and low power consumption. The SN74CB3Q3245PW is often used in high-performance applications such as Ethernet and Fibre Channel. The following will discuss the application field and working principle of the SN74CB3Q3245PW.

Application Field

The SN74CB3Q3245PW application field mainly covers High-Speed Signaling (HSS) applications. It is an ideal device for high-performance applications such as Ethernet and Fibre Channel. The switching speeds provided by this model are up to 25Gs/s and up to 40,000V/s at the high-speed edge. As a result, it is suitable for applications requiring high levels of data accuracy, swift and reliable signal routing, and signal amplification.

Furthermore, the SN74CB3Q3245PW has been designed with a low power consumption of 3.2mA All Channel on, 1.25mA All Channel Off, 3.2uA All Channel Off, and 0.45mA Standby Current. This makes this device ideal for applications where low power consumption is essential, such as computer memory, peripheral device turbines, and handheld devices.

Working Principle

The SN74CB3Q3245PW’s function is two-fold: it is a low voltage CMOS 8-bit multiplexer plus a differential bus switch in a single 64 pin package. The multiplexer functions as a demultiplexer and offers differential bus switching at the same time. The multiplexer is used to route signals from a common input to one of eight output channels based on the selection provided on the control lines. The eight outputs are inverted with respect to the common Thanks to its differential signaling, the SN74CB3Q3245PW can provide a more reliable data transfer compared to single-ended signaling.

Furthermore, the SN74CB3Q3245PW offers high switched speeds. Its bus switch can perform high speed toggling with a response time of up to 25Gs/s and up to 40,000V/s at the high-speed edge. This ensures fast and reliable signal routing to each channel. It also offers a very low on-state output voltage of 0.4V, making it well suited for transistor-transistor logic (TTL) applications. Additionally, the SN74CB3Q3245PW contains high-integrity Bidirectional Latch, enabling it to be used as a level shifter as well.
