MAX4614EUD

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4614EUD is a quad, low-voltage, high-speed, single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2V to +5.5V supply and features four normally open switches within a 14-pin TSSOP package. The device guarantees an on-resistance of 10Ω maximum at +5V supply and 20Ω maximum at +3V supply. Switching times are specified as 12ns turn-on and 10ns turn-off at +25°C. Off-leakage current remains below 6nA across the operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the exact package type and temperature rating. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure proper power-supply sequencing is implemented during integration to protect the CMOS inputs and prevent latch-up conditions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when pin compatibility with legacy 74HC4066 designs is required alongside improved speed and lower leakage specifications. Consider the 10Ω on-resistance limit for signal integrity in precision applications. Verify that the single-supply voltage range aligns with the system's available power rails and logic thresholds.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4614/MAX4615/MAX4616 family of quad SPST analog switches. The MAX4614 variant specifically provides four normally open channels, distinguishing it from the MAX4615 (four NC) and MAX4616 (two NO/two NC). The E-series designation indicates industrial temperature operation (-40°C to +85°C), while the U suffix denotes the 14-pin Thin Shrink Small Outline Package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the MAX4610 and standard 74HC4066 logic gates, though electrical performance may differ. Other members of the same family, such as the MAX4615 or MAX4616, offer alternative switch states but share identical pinouts and packaging constraints.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4614 handle signals exceeding the supply rails?

Signals on the NO_, NC_, or COM_ pins that exceed V+ or GND are clamped by internal diodes. Designers must limit the forward-diode current to the maximum continuous current rating to avoid damage.

What is the guaranteed on-resistance flatness over the signal range?

The on-resistance is guaranteed to be flat within 1Ω maximum over the specified analog signal range, ensuring consistent switching performance regardless of the input voltage level.

Is TTL logic compatibility guaranteed at all supply voltages?

TTL/CMOS logic compatibility is guaranteed when using a single +5V supply. If external protection diodes are added for overvoltage protection, TTL compatibility may not be guaranteed at lower supply voltages due to shifted logic thresholds.
