Product details
Overview
MAX4615CUD+T from Analog Devices is a quad, normally closed (NC), low-voltage, high-speed SPST CMOS analog switch in 14-pin TSSOP package. It operates from +2V to +5.5V, delivers ≤10Ω on-resistance at +5V, matches channels within 1Ω max, and achieves 12ns tON/10ns tOFF. It enables rail-to-rail signal routing in battery-powered audio/video multiplexing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4615CUD+T datasheet, MAX4615CUD+T pinout, MAX4615CUD+T application, or MAX4615CUD+T equivalent, key selection criteria include guaranteed NC configuration, matched on-resistance across all four switches, sub-10nA off-leakage at +85°C, TTL/CMOS logic compatibility at +5V, and TSSOP-14 thermal performance up to +70°C ambient.
Technical Context
The MAX4615CUD+T implements four independent normally closed analog switches using complementary CMOS topology, with each channel supporting bidirectional rail-to-rail signal handling from GND to V+. Its control inputs accept TTL/CMOS thresholds (0.8V/2.4V) and drive internal gate drivers that fully enhance both NMOS and PMOS transistors for low RON and flatness.
On-resistance matching (≤1Ω max) and flatness (≤1Ω max over full signal range) are guaranteed across temperature and supply voltage, enabling precision signal routing without gain error or crosstalk-induced distortion. Off-isolation exceeds –85dB at 100kHz, and charge injection is limited to 6.5pC - critical for sample-and-hold accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V - supports single-supply operation in Li-ion (3.3V/3.7V) and 5V logic systems without level-shifting. |
| On-Resistance (RON) | 10Ω max at +5V - ensures minimal insertion loss and signal attenuation in audio and sensor signal paths. |
| RON Match Between Channels | 1Ω max - guarantees consistent gain and timing across parallel-switched channels in multi-path routing. |
| Off-Leakage Current | 6nA max at +85°C - preserves signal integrity in high-impedance sample-and-hold and sensor front-ends. |
| Switching Speed | tON = 12ns, tOFF = 10ns - enables reliable switching of audio-band and low-MHz digital control signals. |
| Off-Isolation | –85dB at 100kHz - suppresses crosstalk between inactive and active signal paths in A/V matrix applications. |
| Charge Injection | 6.5pC - limits voltage glitch on hold capacitors, reducing settling error in precision data acquisition. |
Pinout & Package
MAX4615CUD+T is housed in a 14-pin Thin Shrink Small Outline Package (TSSOP) with 0.65mm pitch, 5.0mm × 4.4mm body, and exposed pad for thermal enhancement. The package supports reflow soldering per JEDEC J-STD-020 and operates up to +70°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NC1–NC4 | Normally closed analog terminals - conduct to COMx when INx = LOW; open when INx = HIGH. |
| 2, 4, 9, 10 | COM1–COM4 | Common bidirectional analog nodes - connect to NCx when switch is closed; isolated when open. |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - TTL/CMOS-compatible; LOW closes corresponding NC switch. |
| 7 | GND | Analog/digital ground reference - must be low-impedance and shared with signal return path. |
| 14 | V+ | Positive supply - powers analog switch core and input buffers; must be decoupled with 0.1µF ceramic. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from GND to V+ - eliminates clipping in single-supply audio and sensor interfaces. |
| Guaranteed NC configuration | All four switches default closed - simplifies fail-safe design in power-gating and safety-critical routing. |
| Matched on-resistance (≤1Ω) | Minimizes channel-to-channel gain mismatch in differential or multi-path signal conditioning circuits. |
| Flat on-resistance (≤1Ω variation) | Maintains linear transfer function across full signal swing - essential for low-distortion audio routing. |
| TTL/CMOS logic compatibility | Operates directly with 5V microcontrollers and FPGAs - no external level shifters required. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4615EUD+ | Same functionality, extended temperature range (–40°C to +85°C); identical pinout and electrical specs. | Suitable for automotive or industrial environments requiring wider thermal operation. | Select MAX4615EUD+ when operating beyond +70°C ambient or requiring AEC-Q200-aligned qualification. |
| ADG1414BRUZ | Quad SPST, but normally open (NO); 1.5Ω RON match; higher 12V max supply; 16-TSSOP package. | Requires logic inversion for NC behavior; not drop-in due to different pin count and NO default state. | Choose ADG1414BRUZ only if NO default is acceptable and higher voltage tolerance (+12V) is needed. |
Compared with MAX4615CUD+T, MAX4615EUD+ offers identical performance with extended temperature capability, while ADG1414BRUZ provides tighter RON matching and higher voltage rating but requires PCB redesign and logic adaptation due to NO default and 16-pin footprint.

FAQ
What is the default switch state of MAX4615CUD+T?
The MAX4615CUD+T features four normally closed (NC) analog switches. When all IN1–IN4 inputs are held LOW (≤0.8V), all four NC–COM paths conduct. Applying HIGH (≥2.4V) to any INx opens the corresponding NC switch. This fail-closed behavior ensures signal continuity during power-up or controller reset - a key safety feature in MAX4615CUD+T-based designs.
Does MAX4615CUD+T support rail-to-rail analog signals?
Yes, MAX4615CUD+T supports rail-to-rail analog signal handling from GND to V+, verified across its full +2V to +5.5V supply range. Signals applied to NCx or COMx terminals may swing continuously between these rails without clipping or increased distortion - a capability confirmed in the device's Absolute Maximum Ratings and Electrical Characteristics tables for MAX4615CUD+T.
What is the maximum off-leakage current of MAX4615CUD+T at elevated temperature?
The maximum off-leakage current for MAX4615CUD+T is specified as 6nA at TA = +85°C, measured at NOx or NCx terminals with V+ = 5.5V and VCOM = 1V or 4.5V. This value is 100% tested at hot temperature and guaranteed by correlation at +25°C - a critical parameter for maintaining accuracy in high-impedance sample-and-hold or sensor-multiplexing circuits using MAX4615CUD+T.
Can MAX4615CUD+T operate from a 3.3V supply?
Yes, MAX4615CUD+T is fully functional at +3.3V supply. At this voltage, typical on-resistance rises to 20Ω (max), tON/tOFF remain ≤15ns/12ns, and logic inputs retain TTL/CMOS compatibility with VIN_H ≥ 2.0V and VIN_L ≤ 0.8V. All specifications for MAX4615CUD+T - including leakage, bandwidth, and charge injection - are validated down to +2V, making it ideal for modern low-voltage embedded systems.
Is MAX4615CUD+T pin-compatible with industry-standard analog switches?
Yes, MAX4615CUD+T is pin-compatible with the industry-standard 74HC4066 and MAX4610 analog switches, sharing identical 14-pin TSSOP pinout, terminal functions, and logic polarity. This allows direct replacement in existing designs without layout changes - a documented interoperability feature explicitly stated in the MAX4615CUD+T General Description and Pin Configurations sections of the datasheet.
