Product details
Overview
The MAX4615CUD from Analog Devices is a quad, normally closed (NC), low-voltage, high-speed SPST CMOS analog switch in 14-pin TSSOP package, operating from +2V to +5.5V supply, with 10Ω max on-resistance at +5V, 12ns turn-on time, and rail-to-rail signal handling from V+ to GND.
For engineers reviewing the MAX4615CUD datasheet, MAX4615CUD pinout, MAX4615CUD application, or MAX4615CUD equivalent, key selection criteria include guaranteed channel matching (≤1Ω), sub-6nA off-leakage at +85°C, TTL/CMOS logic compatibility, and pin compatibility with 74HC4066/MAX4610 for drop-in replacement in battery-powered and audio routing designs.
Technical Context
The MAX4615CUD implements four independent normally closed analog switches using CMOS transmission-gate architecture, each supporting bidirectional rail-to-rail analog signals (0V to V+) with matched on-resistance across channels. Its logic inputs accept TTL/CMOS thresholds (0.8V/2.4V at +5V) and operate down to +2V supply without level shifting.
Switching performance is optimized for low charge injection (6.5pC) and high dynamic isolation (–85dB off-isolation at 100kHz), enabling precision sample-and-hold and low-distortion audio routing. The device guarantees flat on-resistance (≤1Ω variation over full signal range) and tight channel-to-channel matching (≤1Ω max ΔRON), critical for multiplexer accuracy in data-acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V - supports single-supply operation in Li-ion and 3.3V/5V systems without external regulators |
| On-Resistance (max) | 10Ω at +5V - ensures minimal signal attenuation and voltage drop in sensor/mux paths |
| On-Resistance Match | ≤1Ω max between channels - enables accurate gain/offset matching in differential or multi-channel routing |
| Turn-On / Turn-Off Time | 12ns / 10ns at +5V - supports high-speed switching in communication and sampling applications |
| Off-Leakage Current | ≤6nA at TA = +85°C - preserves signal integrity in high-impedance sample-and-hold and battery-monitoring circuits |
| Analog Signal Range | 0V to V+ - allows full-rail signal handling without clipping in unipolar systems |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V at +5V) - eliminates need for level translators when interfacing with microcontrollers |
Pinout & Package
MAX4615CUD is housed in a 14-pin TSSOP package (3.0mm × 4.4mm, 0.65mm pitch), rated for 0°C to +70°C operation. Thermal resistance θJA is 159°C/W; maximum continuous power dissipation at +70°C is 500mW.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NC1–NC4 (Normally Closed) | Bidirectional analog terminals closed when INx = LOW; open when INx = HIGH |
| 2, 4, 9, 10 | COM1–COM4 (Common) | Central analog node per switch; connects to NCx when enabled, isolated when disabled |
| 5, 6, 12, 13 | IN1–IN4 (Logic Control) | Active-low digital inputs - LOW enables NC path, HIGH opens switch |
| 7 | GND | Ground reference for analog and digital circuitry; must be low-impedance for leakage control |
| 14 | V+ | Positive supply input; powers analog core and logic; absolute max = +6V |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4610CUD | Same pinout, but dual SPST (2-channel); higher RON (15Ω max at +5V); no guaranteed match spec | Suitable only for non-matched dual-path use; insufficient for quad-channel precision mux | Select MAX4615CUD when four matched NC switches or quad routing is required |
| ADG1414BRUZ | Quad SPST NC, 1.5Ω typical RON, but 12V max supply; not 2V–5.5V compatible; larger 16-TSSOP package | Requires higher supply; incompatible with 2.5V/3.3V-only systems; needs PCB layout change | Choose MAX4615CUD for low-voltage battery operation and drop-in 14-TSSOP fit |
Compared with MAX4610CUD and ADG1414BRUZ, the MAX4615CUD uniquely delivers quad NC functionality with guaranteed 1Ω matching, 2V–5.5V operation, and industry-standard 14-TSSOP footprint-making it optimal for space-constrained, low-voltage, precision analog routing where channel consistency and supply flexibility are critical.

FAQ
What is the maximum supply voltage rating for the MAX4615CUD?
The MAX4615CUD has an absolute maximum supply voltage (V+) of +6V, but its specified operational range is +2V to +5.5V. Operating beyond +5.5V risks exceeding guaranteed performance specs, including on-resistance, leakage, and timing. The device is not rated for continuous operation at +6V; sustained use above +5.5V may compromise reliability and parametric compliance. Always refer to the Absolute Maximum Ratings table in the official datasheet for stress limits.
Is the MAX4615CUD pin-compatible with the 74HC4066?
Yes, the MAX4615CUD is explicitly designed as a pin-compatible upgrade to the industry-standard 74HC4066. Both share identical 14-pin TSSOP pinout, logic polarity (active-low control), and terminal labeling (COM/NC). However, the MAX4615CUD improves on key parameters: lower on-resistance (10Ω vs. ~50Ω), faster switching (12ns vs. ~40ns), and guaranteed channel matching (≤1Ω vs. unspecified), making it a functional and mechanical drop-in replacement.
Does the MAX4615CUD support rail-to-rail analog signals?
Yes, the MAX4615CUD supports true rail-to-rail analog signal handling: analog terminals (COM, NC) operate from 0V to V+, with no headroom requirement. This is achieved via internal level-shifting circuitry that maintains switch conduction across the full supply range. Signals at GND or V+ are passed without clipping or increased distortion, enabling direct interface with unipolar sensors, DACs, and ADCs in single-supply systems.
What is the off-leakage current specification for MAX4615CUD at elevated temperature?
The MAX4615CUD guarantees ≤6nA maximum off-leakage current (INO(OFF) and ICOM(OFF)) across its full operating temperature range of 0°C to +70°C. This value is 100% tested at +70°C and correlated at +25°C. At +85°C (outside its C-grade rating), leakage rises to ≤6nA per the extended-grade MAX4615EUD spec - confirming thermal stability critical for battery monitoring and high-temperature industrial sensing.
Can the MAX4615CUD be used with a 2.5V supply?
Yes, the MAX4615CUD operates fully specified down to +2.5V supply. At +2.5V, on-resistance increases to 100Ω max (vs. 10Ω at +5V), and switching times extend to ~6.5ns tON/2.8ns tOFF. Logic thresholds scale accordingly (VINL = 0.5V, VINH = 0.7×V+), maintaining compatibility with 2.5V CMOS controllers. Performance remains functional and guaranteed - ideal for ultra-low-power IoT sensor nodes.
