MAX379EPE

Interface - Analog Switches, Multiplexers, Demultiplexers

The MAX379EPE is a precision, low-power, low-voltage, quad SPST analog switches designed to operate in 2.7V to 5.5V single-supply or split-supply applications. The MAX379EPE has an extended signal range of -0.5V to +6V and a guaranteed break-before-make switching action that enhances settling time and eliminates crosstalk.

The MAX379EPE can be used as part of multiplexer and demultiplexer circuits, for signal switching and routing, for filter cut-off selection, as well as for other general switching applications. It is available in a 14-pin TSSOP/PDIP package. The MAX379EPE is supplied in a ‘Quick Switch’ mode that provides quick power-up and down operation.

Application Field

The MAX379EPE is a unidirectional quad-SPST (single-pole-single-throw) analog switch that can be used in various applications. It is a useful device for filter cut-off selection, signal routing, multiplexer and demultiplexer circuits, as well as other general switching applications. It can be used to multiplex four signals, which is useful in test and instrumentation applications where each path can be utilized in separate subsystems or instruments. It can also be used in audio applications, such as speaker selection or equalizers, as well as in video applications, such as switching video inputs or outputs.

Working Principle

The MAX379EPE is a low-power analog switch controlled by an on-chip CMOS logic. The on-chip logic enables the device to be operated from a single logic supply (2.7 V to 5.5 V). The AX379EPE provides fast switching times (t OFF and t ON of 100 ns and 75 ns, respectively) to minimize distortion, settling time, and crosstalk in high-resolution applications. The MAX379EPE includes four input pins and four output pins. The outputs of the MAX379EPE switch to their respective inputs when the logical inputs are HIGH. When the logical inputs are LOW, the outputs are switched to their respective HIGH-Z (disconnected) state.

Conclusion

The MAX379EPE is a precision, low-power, low-voltage, quad SPST analog switch designed to operate in a variety of applications. It can be used in multiplexer and demultiplexer circuits, for signal switching and routing, for filter cut-off selection, as well as for other general switching applications. Furthermore, the MAX379EPE is supplied in a ‘Quick Switch’ mode that provides quick power-up and down operation, thus making it a very useful device.
