PI5C3125QE

Logic - Signal Switches, Multiplexers, Decoders

The PI5C3125QE is a High Voltage Signal Switch designed for low data loss and wide input and output range. It contains a combination of one high-voltage rail-to-rail non-inverting buffer, controlled by a single high voltage control signal (multiplexer), and two cascaded high voltage buffers that can select up to four input signals which are directed to a common output (decoder).

Application Field

The PI5C3125QE is ideal for switching multiple high voltages with a single control signal. This includes applications where multiplexing and decoding is required in 8 bit or 16 bit data transfers such as high-voltage level shifting, CCD driver and multiplexer, wide-voltage pulse generator, etc. It has a wide operating voltage range from 4.5 to 28V and a low standby current of only 20nA. This makes it suitable for low-power or mobile applications.

Working Principle

The PI5C3125QE utilizes two distinct sets of control signals, a multiplexer control signal and a decoder control signal. The multiplexer control signal is fed into the non-inverting buffer, which controls whether the inputs of the buffer are connected to the upper or lower half of the chip. This allows the user to select up to four of the eight inputs and direct them to a common output. The decoder control signal is then used to activate the two cascaded buffers, which direct the selected input signals to their designated output. So, for example, the user can select four inputs, then choose which one of them is connected to the output.

Additionally, the PI5C3125QE is designed with a slew rate of up to 200V/μs, which ensures high-speed operation and low data loss. It also supports a wide input and output voltage range, making it suitable for use in a wide range of applications.

Conclusion

In conclusion, the PI5C3125QE is a high voltage signal switch perfect for applications where multiplexing and decoding is required. Its low standby current and wide operating voltage range makes it an ideal choice for low-power or mobile applications. Its slew rate of 200V/μs ensures fast operation and low data loss, while its wide input and output voltage range makes it suitable for a wide range of applications.
