MAX4604ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4604ESE is a quad single-pole single-throw (SPST) CMOS analog switch featuring four normally closed channels in a 16-pin Narrow SOIC 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 and flatness of 0.5Ω over the signal range. Key electrical parameters include a maximum off-leakage current of 2.5nA at +85°C, turn-on time of 120ns, and turn-off time of 130ns. It supports continuous currents up to 100mA and handles rail-to-rail analog signals.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'E' confirms the extended temperature range of -40°C to +85°C and the 'SE' indicates the 16-pin Narrow SOIC package. Confirm RoHS compliance status as '+'. Ensure the component matches the original Maxim Integrated specifications before integration into designs requiring precise analog switching characteristics.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when replacing mechanical relays in applications demanding lower board space and higher reliability. Choose the MAX4604 variant specifically for circuits requiring normally closed default states. Verify that the required signal range fits within the specified single or dual supply voltages to ensure proper operation without exceeding absolute maximum ratings.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4604/MAX4605/MAX4606 family of 5Ω quad SPST CMOS analog switches. While the MAX4605 offers normally open switches and the MAX4606 provides a mixed configuration, the MAX4604 is distinct for its four normally closed channels. All variants share identical electrical performance metrics regarding resistance, leakage, and speed.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the default state of the switches in the MAX4604?

The MAX4604 features four normally closed (NC) switches, meaning the connection between COM and NC is established by default until a logic high signal is applied.

How does the on-resistance behave over the signal range?

The on-resistance is guaranteed to be flat with a maximum variation of 0.5Ω over the specified signal range, ensuring consistent signal transmission characteristics.

Is the MAX4604 compatible with standard logic families?

Yes, it has TTL/CMOS-compatible control inputs with logic thresholds of +0.8V and +2.4V, ensuring compatibility when using ±15V supplies or a single +12V supply.
