MAX4605ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4605ESE is a quad single-pole single-throw (SPST) CMOS analog switch featuring four normally open channels in a 16-pin Narrow SO package. It operates from a single supply of +4.5V to +36V or dual supplies of ±4.5V to ±20V. The device guarantees a maximum on-resistance of 5Ω with a match between channels of 0.5Ω max and flatness of 0.5Ω max over the signal range. Key electrical parameters include an off-leakage current of 2.5nA max at +85°C, turn-on time of 120ns, and turn-off time of 130ns. It supports continuous currents up to ±100mA and offers TTL/CMOS-compatible control inputs.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Rail-to-Rail signal handling capability for low-distortion applications
• Guaranteed on-resistance matching and flatness across the specified signal range
• TTL/CMOS logic compatibility ensuring reliable interface with standard digital controls

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in electronic systems
• Automatic test equipment requiring current switching
• Audio-signal routing and communication systems
• PBX and PABX telephony infrastructure

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' confirms the -40°C to +85°C industrial temperature rating and the 'SE' indicates the 16-pin Narrow SOIC package. Confirm RoHS compliance status as original Maxim documentation may predate modern directives. Ensure the ordering code matches the exact quad SPST NO configuration required for the design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high voltage single-supply operation up to 36V is required alongside low distortion performance. The guaranteed Ron flatness makes it suitable for precision signal paths where resistance variation affects accuracy. Consider the package thermal dissipation limits if multiple channels are driven near the 100mA continuous current rating simultaneously.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4604/MAX4605/MAX4606 family of quad analog switches. While sharing identical electrical characteristics and pinouts, the MAX4605 differs from the MAX4604 by using normally open contacts instead of normally closed ones. The MAX4606 combines two NC and two NO switches within the same package architecture.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4604ESE (Normally Closed) and MAX4606ESE (Mixed NC/NO). For lower voltage applications, the MAX4652 series offers similar functionality but operates at reduced supply voltages.
