MAX4615EUD

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4615EUD is a quad, low-voltage, high-speed, single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally closed (NC) switches within a 14-pin TSSOP package. The device operates from a single +2V to +5.5V supply and handles rail-to-rail analog signal levels. Key electrical parameters include a maximum on-resistance of 10Ω at +5V supply and 20Ω at +3V supply, with channel matching guaranteed to 1Ω max. 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 Feature Summary

• Pin-compatible with industry-standard 74HC4066/MAX4610 devices for direct replacement in existing designs.
• Provides fast switching performance with 12ns turn-on and 10ns turn-off times.
• Ensures signal integrity through guaranteed on-resistance matching of 1Ω max and flatness over the signal range.
• Supports TTL/CMOS logic compatibility with defined input voltage thresholds.

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery-operated equipment
• Audio/video signal routing
• Low-voltage data-acquisition systems
• Sample-and-hold circuits
• Communication circuits

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EUD' corresponds to the extended temperature range (-40°C to +85°C) and TSSOP-14 package configuration required for the target application. Confirm that the normally closed (NC) switch topology aligns with the circuit design, as this differs from the normally open variants in the same family. Ensure power sequencing guidelines are followed during integration to prevent latch-up or damage.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4615EUD when a quad SPST switch with normally closed contacts is required for low-voltage applications. Consider the 10Ω on-resistance limit at +5V operation and the 1µA maximum supply current for power-sensitive designs. Verify that the 70MHz bandwidth and charge injection characteristics meet the signal fidelity requirements of the specific analog path.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4615EUD belongs to the MAX4614/MAX4615/MAX4616 family of low-voltage, high-speed CMOS analog switches. These components share identical pinouts and physical dimensions, differing primarily in their internal switch configurations: MAX4614 offers four normally open switches, MAX4615 provides four normally closed switches, and MAX4616 combines two of each. This family is designed for direct pin-to-pin replacement of legacy 74HC4066 equivalents.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4615EUD is pin-compatible with the MAX4610 and 74HC4066. When substituting, verify that the original component's normally closed state matches the MAX4615 functionality, as standard replacements often default to normally open states.
