MAX335CWG+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX335CWG+ is a CMOS analog switch IC featuring eight individually controlled single-pole-single-throw (SPST) switches. It utilizes an SPI-compatible serial digital interface for control, allowing multiple devices to be daisy-chained. The device operates with dual power supplies ranging from ±4.5V to ±20V and handles rail-to-rail analog signals. Key electrical parameters include a maximum on-resistance of 150Ω at +25°C, turn-on/turn-off times up to 500ns, and off-isolation of 90dB at 100kHz. It is housed in a 24-pin Wide SO package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CWG corresponds to the 24-pin Wide SO package and commercial temperature range during sourcing. Confirm RoHS compliance status as indicated by the '+' designation. Check current availability as this component may be subject to lifecycle changes or discontinuation notices from Analog Devices.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX335CWG+ when a serial interface is required to minimize pin count compared to parallel-controlled switches. Ensure the system voltage does not exceed ±20V. Consider the 150Ω maximum on-resistance for signal integrity requirements. Verify that the 0°C to +70°C temperature range meets the environmental constraints of the target application.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX335 family of serial-controlled analog switches manufactured by Analog Devices / Maxim Integrated. It serves as a compact alternative to discrete switch arrays, integrating eight channels into a single package. The part is designed for applications requiring efficient signal routing with minimal microcontroller I/O usage.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional equivalents are limited due to the specific serial interface. Review the MAX336 series for higher channel counts or different packaging options. Consult manufacturer documentation for any updated revisions or recommended upgrades within the same product line.
