MAX335ENG

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX335ENG is a serial-controlled analog switch featuring eight independently controlled single-pole-single-throw (SPST) channels. It operates with dual power supplies ranging from ±4.5V to ±20V and handles rail-to-rail analog signals up to ±15V. The device utilizes an SPI-compatible three-wire serial interface for data input and output, allowing multiple units to be daisy-chained. It is housed in a 24-pin narrow plastic DIP package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix ENG corresponds to the 24-pin narrow plastic DIP package and the industrial temperature range of -40°C to +85°C. Confirm that the component meets all required electrical specifications for your target voltage and signal conditions before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a compact solution for multiple analog switches is required without consuming numerous parallel I/O lines. The serial interface reduces pin count significantly compared to parallel alternatives. Ensure the system clock frequency does not exceed the maximum specified limit for reliable data shifting.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX335 family of serial-controlled analog switches. It provides functionality equivalent to two quad switches but managed via a serial protocol. Other variants in the series include different packages and temperature ratings, such as the CNG for commercial use or the MRG for military-grade extended temperatures.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements within the same package and specification are limited due to the proprietary serial interface. Verify compatibility with existing SPI controllers if substituting with other serial switches. Cross-reference pinouts carefully as alternative devices may differ in channel count or control logic.
