MAX333CAP

MAX333CAP Interface - Analog Switches, Multiplexers, Demultiplexers

The MAX333CAP is a CMOS, low voltage, 8-channel analog multiplexer/demultiplexer device. It provides a high-isolation barrier between channels and is capable of multiplexing or demultiplexing in either direction, allowing flexible routing of analog and digital signals. Each of the eight multiplexer/demultiplexers on the device are controlled by a single Enable pin, making them ideal for applications such as analog multiplexing, signal demodulation, and multiplexing/demultiplexing mixed signal and asynchronous digital signals. In addition, the MAX333CAP is equipped with an integrated charge pump and level shifting, allowing for it operate from a single supply voltage of 0V-5V.

Applications

The MAX333CAP is suited for a number of applications, including analog multiplexing, signal demodulation, multiplexing/demultiplexing mixed signal and asynchronous digital signals, and level shifting. In addition, the device can be used for analog signal mixing and signal conditioning. Other applications include determining the date and time in a clock by measuring the difference between two signals, and sequencing the input and output of multiple channels. The device is also capable of providing an optical isolation barrier between two mismatched signal sources, making it an ideal solution for applications such as LED backlighting and panel data switching.

Working Principle

The MAX333CAP is a CMOS multiplexer/demultiplexer that allows for the connection of up to eight separate channels. Each of the eight channels is independently enabled or disabled by a single Logic High input signal. When the Logic High input is applied to the Enable pin, the associated channel is connected to the selected input or output. The device operates from a single +5V Vcc power supply, and has an internal charge pump that supplies the necessary voltage for the channel switching transistors.

The MAX333CAP is primarily used for analog channel switching and signal routing. All channel switching is done by the channels\' independent enable logic signals. Additionally, the charge pump voltage is coupled with one of the logic inputs of each channel, allowing for the switching of channels to be done at logic low level, which makes the MAX333CAP suitable for level shifting applications. The logic control signals can be a combination of either logical high or logical low states.
