The SN74CBT16212ADLRG4 is a high-performance, low voltage, 16-bit registered crosspoint switch from Texas Instruments. This device belongs to the family of logic - signal switches, multiplexers and decoders. The SN74CBT16212ADLRG4 device is designed for interfacing applications requiring multiple switch configurations with high speed and low-power requirements. This section reviews its application field, design features, and principle of operation.

Application Field

The SN74CBT16212ADLRG4 is intended for use in applications such as high-performance memory systems, communications systems, system switching and control, image processing, digital video, and industrial control systems. It is designed to interface switch configurations with minimal propagation delay and highest levels of performance and low-power applications. It is focused on reducing size and increasing switching speeds in applications where space and power dissipation is a concern.

Design Features

The SN74CBT16212ADLRG4 Crosspoint switch uses advanced silicon-on-insulator (SOI) process technology to reduce power consumption and increase switching performance. This device also features an independent power down feature to reduce power consumption further, when the switch is not in use. The SN74CBT16212ADLRG4 also provides excellent signal propagation delay, high-speed switching, and improved noise performance.

The SN74CBT16212ADLRG4 Crosspoint switch has a “virtual earth” feature which helps to optimize the layout and reduce the number of lines and tracks. This device also features an internal register to store the switch settings, so that they can be retrieved when necessary. As an added benefit, the register settings are saved if the power is turned off.

Working Principle

The functioning of the SN74CBT16212ADLRG4 can be divided into two modes: the multiplexer mode and the linear mode. In the multiplexer mode, input signals are routed to different outputs, while in the linear mode, a single input is routed to a desired output.

In the multiplexer mode, the device functions by selecting one of the two inputs and then routing them to a single output port. The selection of the input is accomplished by a dual multiplexer and the output is then connected to the register, allowing the data to be stored. With the register storing the data, an internal logic circuit is used to determine the corresponding output.

In the linear mode, the device functions by selecting one input data across all sixteen channels, and routing them to the same output. This is achieved by first connecting the data to the register, which stores the information. Then, a logic circuit determines the output path for the corresponding input data and routes the data accordingly.

Conclusion

The SN74CBT16212ADLRG4 is a high-performance, low voltage, 16-bit, logic - signal switch multiplexer and decoder. This device is designed for applications requiring multiple switch configurations with high speed and low-power requirements. The SN74CBT16212ADLRG4 Crosspoint switch uses advanced silicon-on-insulator (SOI) process technology to reduce power consumption and increase switching performance. In the multiplexer mode, input signals are routed to different outputs while in the linear mode, a single input is routed to a desired output. This device offers excellent signal propagation delay, high-speed switching, and improved noise performance.
