MAX335EUG+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX335EUG+ is a serial-controlled analog switch featuring eight independently controlled single-pole-single-throw (SPST) channels in a 24-pin TSSOP package. It operates on dual power supplies ranging from ±4.5V to ±20V, or a single supply of +10V to +30V when V- is grounded. The device handles rail-to-rail analog signals with an on-resistance of 150Ω maximum and accepts ±15V analog swings. Powered by a CMOS process, it draws a maximum supply current of 500µA at +25°C. The component supports an operating temperature range of -40°C to +85°C and includes a reset function triggered by the VL pin.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EUG+' against official manufacturer documentation to confirm the exact temperature grade and lead-free status. Ensure the ordering code matches the required 24-pin TSSOP package dimensions. Cross-reference the part number with authorized distributors to confirm current availability and compliance with relevant environmental standards.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring multiple analog switches managed by a microcontroller using standard serial protocols. Verify that the system power rails fall within the ±4.5V to ±20V range for optimal performance. Consider the 150Ω maximum on-resistance and 2pF off-capacitance when designing high-frequency signal paths. Ensure the logic supply voltage aligns with the processor's I/O levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX335 family of serial-controlled analog switches manufactured by Analog Devices Inc./Maxim Integrated. It serves as a digital equivalent to discrete mechanical relays or parallel-switch ICs, offering space savings in dense PCB layouts. The E variant denotes the extended industrial temperature range suitable for demanding environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet notes that the MAX335 is electrically equivalent to two DG211 quad switches combined into a single serial-controlled unit. Designers replacing parallel-switch ICs should account for the shift in control architecture from parallel inputs to a serial clock interface.
