Product details
Overview
MAX4615EPD from Analog Devices is a quad, high-speed, single-pole/single-throw (SPST) CMOS analog switch with normally closed (NC) configuration, operating from +2V to +5.5V supply. It delivers 10Ω max on-resistance at +5V, 1Ω max channel-to-channel on-resistance match, and 12ns turn-on / 10ns turn-off times. It supports rail-to-rail analog signal handling (0V to V+) and is used in low-voltage audio routing and battery-powered data-acquisition systems.
For engineers reviewing the MAX4615EPD datasheet, MAX4615EPD pinout, MAX4615EPD application, or MAX4615EPD equivalent, key selection criteria include NC-switch topology, -40°C to +85°C industrial temperature rating, 14-pin plastic DIP package, leakage current ≤6nA at +85°C, and compatibility with TTL/CMOS logic levels at +5V supply.
Technical Context
The MAX4615EPD implements four independent NC SPST switches using matched CMOS transmission-gate architecture. Each switch features bidirectional signal flow, guaranteed on-resistance flatness of ≤1Ω over its full 0V to V+ analog range, and logic inputs with fixed 0.8V/2.4V thresholds for robust TTL/CMOS interfacing.
Its design targets low-distortion, low-charge-injection switching in precision analog paths: THD is 0.034% at 20Hz–20kHz, charge injection is 6.5pC, and off-isolation reaches -85dB at 100kHz. All channels are electrically isolated with crosstalk < -96dB between any pair.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V - Enables direct integration into 2.5V, 3.3V, and 5V systems without level-shifting. |
| On-Resistance (max) | 10Ω at +5V - Ensures minimal signal attenuation and voltage drop in low-level analog paths. |
| On-Resistance Match | 1Ω max between channels - Critical for matched gain/attenuation in multi-channel instrumentation or balanced signal routing. |
| Turn-On / Turn-Off Time | 12ns / 10ns - Supports high-speed multiplexing in sampling systems up to ~35MHz effective rate. |
| Off-Leakage Current | 6nA at TA = +85°C - Preserves accuracy in high-impedance sample-and-hold or sensor front-end circuits. |
| Analog Signal Range | 0V to V+ - Allows true rail-to-rail signal switching without clipping in single-supply designs. |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V at +5V) - Direct interface with microcontrollers and FPGAs without external buffers. |
Pinout & Package
MAX4615EPD uses a 14-pin plastic DIP package (0.300" wide), rated for -40°C to +85°C operation and offering through-hole mounting for prototyping and industrial control applications.
| 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 analog I/O nodes - Bidirectional signal path shared between NCx and internal switch element. |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - Active-low logic: LOW enables NC path, HIGH opens switch. |
| 7 | GND | Ground reference for analog and digital circuitry - Must be low-impedance for noise-sensitive analog routing. |
| 14 | V+ | Positive supply rail - Powers analog switch core and input buffers; must be applied before analog signals. |
Key Features

Use Scenario: Isolating RS-232/RS-485 transceiver lines from MCU UART pins during power-down or fault conditions in fieldbus gateways. IC Role / Device Role / Timing Role: Fail-safe analog switch that defaults to closed (NC) state, maintaining signal continuity unless actively opened. Use Value: NC topology provides inherent "power-loss safe" behavior; 5.5V absolute max rating accommodates transient bus voltages. |
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 |
|---|---|---|---|
| MAX4615ESD | Same electrical specs, but in 14-pin narrow SOIC package - smaller footprint, surface-mount only. | Preferred for space-constrained PCBs; requires reflow assembly instead of through-hole soldering. | Select MAX4615ESD when board area is limited and automated SMT assembly is available. |
| ADG1415BRUZ | Quad NC SPST, 12Ω RON at +5V, -40°C to +125°C rating, 16-pin TSSOP - higher temp grade, different pinout. | Used in automotive or extended-temp industrial environments where +85°C upper limit is insufficient. | Choose ADG1415BRUZ only if extended temperature range or higher reliability qualification is required; not pin-compatible. |
Compared with MAX4615EPD, MAX4615ESD offers identical performance in a compact SOIC package ideal for volume production, while ADG1415BRUZ trades pin compatibility for wider temperature range and higher-grade process - neither is a drop-in replacement, but both serve overlapping analog routing functions in distinct mechanical or environmental contexts.

FAQ
What is the maximum supply voltage for MAX4615EPD?
The absolute maximum supply voltage for MAX4615EPD is +6V, though the recommended operating range is +2V to +5.5V. Exceeding +6V risks permanent damage per Absolute Maximum Ratings. Operation at +5.5V maintains full specification compliance including 10Ω max on-resistance and 6nA max off-leakage at +85°C. The MAX4615EPD datasheet specifies derating curves for power dissipation above +70°C ambient, confirming 800mW continuous rating in the 14-pin plastic DIP package.
Is MAX4615EPD pin-compatible with the 74HC4066?
Yes, MAX4615EPD is pin-compatible with the industry-standard 74HC4066 and MAX4610 analog switches. Its 14-pin DIP layout matches the 74HC4066 pinout exactly: V+ (pin 14), GND (pin 7), COM1–COM4 (pins 2,4,9,10), NC1–NC4 (pins 1,3,8,11), and IN1–IN4 (pins 5,6,12,13). This allows direct substitution in legacy designs without PCB modification, while delivering superior performance including lower on-resistance (10Ω vs. typical 50Ω), faster switching (12ns vs. >40ns), and guaranteed matching.
What does "normally closed" mean for MAX4615EPD?
"Normally closed" means each of the four switches in MAX4615EPD conducts (i.e., connects NCx to COMx) when its corresponding digital control input (INx) is held LOW (≤0.8V). When INx is driven HIGH (≥2.4V), the switch opens, disconnecting NCx from COMx. This fail-safe behavior ensures signal continuity during power-up, reset, or MCU initialization - critical in applications like communication line protection or sensor bias path maintenance where default conduction is required.
Can MAX4615EPD operate from a +3.3V supply?
Yes, MAX4615EPD is fully specified for +3.3V operation. At V+ = +3.3V, it guarantees 20Ω max on-resistance, 1.5Ω max channel match, and 15ns max turn-on time over the full -40°C to +85°C range. Logic inputs retain TTL/CMOS compatibility with VIN_H = 2.0V and VIN_L = 0.8V thresholds. The device draws only 1µA supply current, making it ideal for +3.3V battery-powered systems where low quiescent power and rail-to-rail analog range (0V to +3.3V) are essential design requirements.
What is the off-isolation performance of MAX4615EPD?
MAX4615EPD provides -85dB off-isolation at 100kHz, measured as 20log₁₀(VCOM/VNO/NC) with 50Ω source and load impedances. This specification ensures strong signal rejection between the common terminal and the open NC terminal, preventing unwanted coupling in multi-channel routing. Off-isolation remains effective across frequency - the device maintains >40dB isolation up to 10MHz - supporting clean switching in audio, instrumentation, and communication signal paths where crosstalk must be minimized.
