The MAX4523CSE is a switching multiplexer and demultiplexer designed for use in audio, data, and telecom applications. It is designed for two independent, low-resistive, wideband switches, each capable of carrying several hundred milliamps of current, which can be configured as a multiplexer, a demultiplexer, a single switch, or dual switches. The MAX4523CSE has a 0.2-ohm on-resistance and an “off” resistance of 80 ohms. It is capable of switching frequencies up to 1 MHz and can be used in applications such as video line testing, video multiplexing, digital audio selecing, data acquisition, and modem and tape recorder switching.

The MAX4523CSE uses metal-oxide semiconductor (MOS) switched elements which give it high switching speeds with low resistances. It is designed for use in mixed-signal systems and features a special metal-insulator-metal (MIM) capacitor as the input-signal isolation device. The device is available in the Augusto package, which is the same as the widely used DIP standard package.

When used as a multiplexer, the device connects one of its two inputs to the output of the device based on the binary coded address of the two inputs. When used as a demultiplexer, only one input is required, and this is used to select one of the two outputs. The MAX4523CSE is also capable of being used as a single switch, with one input and one output, or as a dual-switch element, with two inputs and two outputs.

The MAX4523CSE’s low-voltage logic inputs are used to control its switching operation. These logic inputs are TTL/CMOS compatible and can be driven directly from low-voltage logic levels. The MAX4523CSE avoids shoot-through currents associated with many analog switches by simultaneously switching both outputs off when either address input is in the low state. This feature eliminates the need for any additional control circuitry.

The MAX4523CSE’s wideband impedance matching ensures consistent performance over a wide range of frequencies, and its high switching speeds minimize distortion and noise in audio and video applications. The MAX4523CSE is also capable of being used in DC/DC converters and in precision current-measuring circuits.

In summary, the MAX4523CSE is a high-speed, low-resistive switching multiplexer and demultiplexer designed for use in audio, data, and telecom applications. Its 0.2-ohm on-resistance and its “off” resistance of 80 ohms make it ideal for use in applications requiring high current-handling capability with low distortion and noise. The device is available in the popular Augusto package, which is compatible with DIP packages and provides a versatile solution for switching and signal routing applications.
