MAX4600EWE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4600EWE is a dual SPST CMOS analog switch in a 16-pin Wide SO package, featuring one normally open and one normally closed channel. It operates from +4.5V to +36V single or ±4.5V to ±20V dual supplies with TTL/CMOS-compatible inputs. Key electrical parameters include a maximum on-resistance of 1.25Ω (dual supply) or 3Ω (single supply), an on-resistance match of 0.25Ω (dual) or 0.4Ω (single), and flatness of 0.3Ω (dual) or 0.4Ω (single). Turn-on/off times are 160ns/210ns (dual) or 150ns/200ns (single). Leakage current is 2.5nA max at +85°C (dual) or 1nA max (single).

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EWE' corresponds to the -40°C to +85°C temperature range and 16-Wide SO package configuration. Confirm that the ordering information matches the manufacturer's current datasheet revision to ensure pinout and electrical specifications remain consistent with the documented design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mixed configuration of normally open and normally closed switches is required within a single package. Ensure the application voltage does not exceed the absolute maximum ratings of +44V between V+ and GND. Consider the 1.25Ω on-resistance for low-loss signal paths compared to higher resistance alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4580/MAX4590/MAX4600 family of dual analog switches. While the MAX4580 provides two NC switches and the MAX4590 provides two NO switches, the MAX4600 uniquely combines one NC and one NO switch. All variants share identical pinouts and core electrical characteristics, differing only in internal switch logic states.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the same family include the MAX4580EWE and MAX4590EWE. These parts share the same 16-Wide SO package and extended temperature rating but offer different switch configurations (all NC or all NO respectively). Verify that the specific NC/NO combination requirement is met by the alternative part number.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4600 and MAX4580?

The MAX4600 contains one normally open (NO) and one normally closed (NC) switch, whereas the MAX4580 contains two normally closed (NC) switches. Both share the same package and electrical specifications.

How does the on-resistance vary with supply voltage?

On-resistance is specified as 1.25Ω max under dual supply conditions (+/-15V) and 3Ω max under single supply conditions (+12V). The resistance remains flat over the specified signal range.

Is the MAX4600 compatible with standard TTL logic levels?

Yes, the digital inputs have +0.8V and +2.4V logic thresholds, ensuring compatibility with TTL and CMOS logic when using a +12V single supply or +/-15V dual supplies.
