MAX4604CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4604CPE is a quad single-pole single-throw (SPST) CMOS analog switch housed in a 16-pin Plastic DIP package. It features four normally closed switches with a maximum on-resistance of 5Ω, matched to 0.5Ω and flat within 0.5Ω over the signal range. The device supports single supplies from +4.5V to +36V or dual supplies from ±4.5V to ±20V. Operating temperature ranges from 0°C to +70°C. Key electrical parameters include a maximum off-leakage current of 0.5nA at +85°C, turn-on time of 160ns, and turn-off time of 220ns under single-supply conditions.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Handles Rail-to-Rail analog signals across the full supply range
• Offers TTL/CMOS-compatible digital control inputs
• Provides guaranteed on-resistance matching and flatness for low distortion
• Includes ESD protection exceeding 2000V per Method 3015.7

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• Audio-signal routing in PBX and PABX systems
• Communication systems and avionics signal switching

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CPE' confirms the commercial temperature range (0°C to +70°C) and 16-pin PDIP package. Ensure the component source matches the Analog Devices/Maxim Integrated manufacturer designation. Confirm RoHS compliance status if required by assembly specifications, as older batches may differ.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a quad SPST configuration with normally closed logic is required. Compare against MAX4605 (normally open) and MAX4606 (mixed NC/NO) for alternative contact states. Consider the MAX4604ESE variant if an extended industrial temperature range (-40°C to +85°C) or surface-mount packaging is necessary for the design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4604/MAX4605/MAX4606 family of 5Ω quad CMOS analog switches. It serves as a solid-state alternative to mechanical relays, offering lower power consumption and reduced board space. The MAX4604 specifically provides four normally closed channels, distinguishing it from the NO-only MAX4605 and mixed MAX4606 variants.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4604CSE+ offers the same functionality in a 16-SOIC surface-mount package with an extended temperature range. MAX4604EPE provides the same function in a 16-PDIP package but covers -40°C to +85°C.
