The SN74CBT3253CPWR is a 3-to-8 data selector/multiplexer switch, commonly used in multiplexers and decoders. It is a logic signal switch with low-voltage (3.3 to 3.6V) and high-current (8mA) capabilities. The device is available in both the QFN package and the PWR package.

Features and Applications

This device features two enable inputs, two data inputs, and eight data outputs. Each enable input controls the state of one or more of the data outputs. The device draws very low power and its input pins have very low leakage current. Due to its combination of low voltage operation and fast switch times, this device is ideal for use in multiplexers and decoders. It can be used in low-power and low-voltage applications, such as automotive, medical, and industrial used systems. It is also suitable for use in high-speed communication systems such as ethernet, Fibre Channel, and serial I/O systems.

Working Principle

The SN74CBT3253CPWR works on the concept of a Selection Matrix. The two enable inputs control the internal selection matrix. By adjusting the two enable inputs, different subsets of the data outputs are selected. When both enable inputs are HIGH, all the outputs are OFF, while when both enable inputs are LOW, all the outputs are ON. By changing the combination of the two enable inputs, different data outputs can be selected. The device also features two data inputs, and the data is passed through to the selected outputs.

The device is controlled by the two enable inputs, with both enabling the data output. The device also features a maximum output current of 8mA and a maximum low voltage of 3.3 to 3.6V. The device is designed to minimize power consumption and reduce EMI, making it suitable for use in applications such as automotive, medical, and industrial systems.
