Product details
Overview
MAX4615EUD 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 matching, and rail-to-rail signal handling from V+ to GND. Designed for low-leakage signal routing, it supports audio/video switching and battery-operated instrumentation.
For engineers reviewing the MAX4615EUD datasheet, MAX4615EUD pinout, MAX4615EUD application, or MAX4615EUD equivalent, key selection criteria include guaranteed on-resistance flatness (≤1Ω over signal range), sub-12ns switching times, <6nA off-leakage at +85°C, TTL/CMOS logic compatibility, and -40°C to +85°C extended temperature operation in 14-pin TSSOP.
Technical Context
The MAX4615EUD implements four independent NC SPST switches using matched CMOS transmission-gate architecture. Each switch features bidirectional rail-to-rail analog conduction, with guaranteed on-resistance flatness ≤1Ω across the full 0V to V+ signal range and channel matching ≤1Ω at +25°C.
Its digital control inputs meet TTL/CMOS thresholds (+0.8V low, +2.4V high at +5V supply), enabling direct interface with microcontrollers and logic families without level shifting. The device maintains stable performance across its full -40°C to +85°C operating range, with leakage currents fully tested at maximum hot temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V - supports Li-ion, 3.3V, and 5V systems without external regulation |
| On-Resistance (max) | 10Ω at +5V - ensures minimal signal attenuation and voltage drop in precision signal paths |
| On-Resistance Match | ≤1Ω max between channels - enables accurate gain/phase matching in multi-channel routing |
| Off-Leakage Current | ≤6nA at +85°C - preserves signal integrity in high-impedance sample-and-hold or sensor interfaces |
| Switching Speed | tON = 14ns, tOFF = 12ns max - supports high-frequency multiplexing up to 70MHz bandwidth |
| Logic Compatibility | TTL/CMOS thresholds (+0.8V / +2.4V) - allows direct drive from standard digital I/O without buffers |
| Analog Signal Range | 0V to V+ - enables true rail-to-rail signal switching without clipping or distortion |
Pinout & Package
MAX4615EUD is housed in a 14-pin Thin Shrink Small Outline Package (TSSOP) with 0.65mm pitch, optimized for space-constrained PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NC1–NC4 | Normally closed analog terminals - conduct when INx = LOW; bidirectional signal path |
| 2, 4, 9, 10 | COM1–COM4 | Common analog terminals - connect to signal source/load; bidirectional with NC/NO paths |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - active-low logic controls NC switch state (LOW = ON, HIGH = OFF) |
| 7 | GND | Analog/digital ground reference - must be low-impedance connection for leakage and noise control |
| 14 | V+ | Positive supply - powers analog switch core and input buffers; decoupling required per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full 0V to V+ conduction without clamping or distortion - critical for ±2.5V and unipolar sensor signals |
| Guaranteed on-resistance flatness | ≤1Ω variation over entire signal range - eliminates amplitude-dependent nonlinearity in measurement circuits |
| Low charge injection (6.5pC) | Minimizes voltage glitch on sampled nodes - essential for high-resolution data acquisition and sample-and-hold stability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4615CUD | Same electrical specs but rated for 0°C to +70°C only; identical 14-pin TSSOP package | Suitable for commercial-grade consumer electronics where extended temperature is not required | Select MAX4615CUD for cost-sensitive, non-industrial designs with ambient temperatures within 0°C–70°C |
| ADG1414BRUZ | Quad SPST NC switch with 1.5Ω RON max at +5V, higher 120mA continuous current rating, but 16-pin TSSOP package | Requires PCB layout change due to different pin count and footprint; better for high-current analog paths | Choose ADG1414BRUZ only if higher current handling (>75mA) or lower on-resistance (<10Ω) is mandatory and board redesign is acceptable |
Compared with MAX4615CUD, the MAX4615EUD provides guaranteed performance over -40°C to +85°C without electrical trade-offs. Against ADG1414BRUZ, it offers pin-compatible drop-in replacement in 14-pin TSSOP but with slightly higher RON and lower current rating - ideal for space-constrained, thermally demanding signal routing where layout continuity is critical.

FAQ
What is the operating temperature range of the MAX4615EUD?
The MAX4615EUD is specified for operation from -40°C to +85°C. This extended temperature grade is validated across all key parameters including on-resistance, leakage current, and switching speed - making it suitable for industrial, automotive, and outdoor electronics where thermal stability is critical. All electrical characteristics in the datasheet apply across this full range unless otherwise noted.
Does the MAX4615EUD support rail-to-rail analog signal switching?
Yes, the MAX4615EUD supports true rail-to-rail analog signal conduction from GND to V+. Its CMOS transmission-gate architecture allows analog voltages spanning the full supply range (0V to V+) to pass through the NC switches with minimal distortion or clipping - a key requirement for interfacing with sensors, DACs, and op-amps operating near supply rails.
What is the maximum on-resistance of the MAX4615EUD at +3.3V supply?
At +3.3V supply, the MAX4615EUD has a maximum on-resistance of 25Ω over the full -40°C to +85°C temperature range. At +25°C, the typical value is 20Ω. This parameter is guaranteed and tested - ensuring predictable voltage drop and signal integrity in 3.3V systems such as portable instrumentation and embedded controllers.
How does the MAX4615EUD differ from the MAX4614EUD?
The MAX4615EUD contains four normally closed (NC) SPST switches, while the MAX4614EUD contains four normally open (NO) switches. Their pinouts and electrical specifications are identical except for switch default state: MAX4615EUD conducts when control inputs are LOW, whereas MAX4614EUD conducts when inputs are HIGH. Both share the same package, temperature range, and performance metrics.
Is the MAX4615EUD pin-compatible with industry-standard analog switches?
Yes, the MAX4615EUD is pin-compatible with the industry-standard 74HC4066 and MAX4610 analog switches. This allows direct replacement in existing designs without PCB modification, preserving layout integrity while upgrading to lower on-resistance, faster switching, and extended temperature performance - provided the NC functionality aligns with system logic requirements.
