• Low power consumption – 0.4mA (< 10 μA standby).
• Schmitt trigger inputs for improved noise immunity.

Applications

The QS3257QG8 is ideally used in MIL-STD-1553 systems which require multiplexers, signal switches, and decoders. Its compact design makes it ideal for applications where multiplexing, switching, and decoding is required in a small space. The device is also suitable for industrial, medical, and automotive applications where low power consumption and a high level of reliability is needed. The integrated Schmitt trigger inputs, provide an improved noise immunity for enhanced performance in noisy environments.

Working Principle

The QS3257QG8 is a free-base logic - signal switch and multiplexer. Its one of its major functions is to provide a single output with the ability to switch between two multiplexed input signals. The multiplexing and decoding are done by the two 2x2 ROMs and dual multiplexer blocks. The two 2x2 ROMs contain the logic information required to control the two multiplexers. The two multiplexers are then used to select one of the two multiplexed signals, and then this signal is passed through to the output. The low power consumption of the device, along with the high levels of noise immunity, make it ideal for use in a variety of applications.

Conclusion

The QS3257QG8 is a powerful logic - signal switch, multiplexer and decoder, with integrated dual multiplexer switching control. It is ideal for MIL-STD-1553 systems, aircraft accessories, avionics, process control, industrial robotics and active noise control systems. It has a wide range of features, including Schmitt trigger inputs, low power consumption and high level supply voltage, which make it an ideal choice for multiplexing, switching and decoding tasks. Thanks to its low power consumption, it can be used in low power systems.
