Product details
Overview
The MAX4615CUD+ from Analog Devices is a quad, low-voltage, high-speed, single-pole/single-throw (SPST) analog switch with normally closed (NC) configuration, operating from +2V to +5.5V supply, delivering 10Ω max on-resistance at +5V, 1Ω max channel-to-channel on-resistance match, and 12ns turn-on time. It enables rail-to-rail analog signal routing in battery-powered audio/video systems.
For engineers reviewing the MAX4615CUD+ datasheet, MAX4615CUD+ pinout, MAX4615CUD+ application, or MAX4615CUD+ equivalent, this device is selected for low-leakage, high-speed switching in portable instrumentation and precision data-acquisition where NC default state ensures fail-safe signal path closure during power loss.
Technical Context
The MAX4615CUD+ implements CMOS transmission-gate architecture with matched P- and N-channel MOSFETs per switch, enabling rail-to-rail signal handling from GND to V+. Its logic inputs feature fixed TTL/CMOS-compatible thresholds (0.8V low, 2.4V high at +5V), eliminating level-shifter requirements in mixed-supply systems.
All four switches are independently controlled by digital inputs IN1–IN4; each NC switch conducts when input is LOW and opens when HIGH. On-resistance flatness remains ≤1Ω over the full 0V to V+ analog range, ensuring minimal THD (<0.034%) in audio-frequency paths up to 20kHz.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4614CUD+ | Quad NO (normally open) configuration vs. MAX4615CUD+'s NC - complementary default state | Suitable where signal path must be open at power-up; not interchangeable without logic inversion | Select MAX4614CUD+ only when fail-open behavior is required for safety-critical signal isolation |
| ADG1412BRUZ | Higher on-resistance (1.8Ω typ at +5V), wider supply (±15V dual or +3V to +16.5V single), 16-TSSOP package | Targeted at industrial PLC I/O modules requiring higher voltage tolerance and lower leakage (<1pA) | Choose ADG1412BRUZ for ±15V signal conditioning; MAX4615CUD+ remains optimal for low-voltage portable systems |
Compared with MAX4614CUD+, the MAX4615CUD+ provides fail-safe closed-path operation ideal for battery-backed systems; versus ADG1412BRUZ, it offers superior speed (12ns vs. 100ns) and smaller footprint (14-TSSOP vs. 16-TSSOP) at the cost of lower voltage rating.

FAQ
What is the default switch state of MAX4615CUD+?
The MAX4615CUD+ features four normally closed (NC) analog switches - each conducts when its respective INx input is LOW and opens when HIGH. This fail-safe behavior ensures signal continuity during power loss or controller reset, making MAX4615CUD+ ideal for applications like emergency audio pass-through or sensor monitoring where uninterrupted analog path is critical.
Can MAX4615CUD+ operate from a 3.3V supply?
Yes, MAX4615CUD+ operates across +2V to +5.5V. At +3.3V supply, on-resistance is guaranteed ≤20Ω (typ 8Ω), with 15ns max tON and 12ns max tOFF. Logic thresholds remain compatible (VIN_L = 0.8V, VIN_H = 2.0V), allowing direct interfacing with 3.3V microcontrollers without level shifters - a key advantage confirmed in the +3.3V electrical characteristics table.
What is the maximum analog signal voltage supported by MAX4615CUD+?
MAX4615CUD+ supports rail-to-rail analog signals from GND to V+, meaning the maximum analog voltage equals the applied V+ supply voltage - up to +5.5V. Absolute maximum ratings allow transient excursions to -0.3V and V+ +0.03V on COM/NO/NC pins, but sustained operation must stay within GND to V+ to avoid internal diode conduction and leakage increase.
How does MAX4615CUD+ compare to 74HC4066 in pinout and function?
MAX4615CUD+ is pin compatible with 74HC4066 and MAX4610, sharing identical 14-pin TSSOP pin assignments for V+, IN1–IN4, COM1–COM4, NC1–NC4, GND. Unlike 74HC4066, MAX4615CUD+ guarantees 10Ω max on-resistance, 1Ω max channel matching, and 6nA off-leakage at +85°C - delivering superior precision and thermal stability in demanding analog signal paths.
Is thermal performance data available for MAX4615CUD+ in continuous operation?
Yes - MAX4615CUD+'s 14-pin TSSOP package has a 500mW maximum continuous power dissipation at +70°C, derating 6.3mW/°C above that temperature. Measured supply current is <1µA across temperature, and on-resistance increases predictably with junction temperature (see Figure toc02), enabling accurate thermal modeling for compact PCB layouts with minimal heatsinking.
