Product details
Overview
MAX4615CUD-TG068 from Maxim Integrated is a quad, normally closed (NC), single-pole/single-throw (SPST) CMOS analog switch operating from +2V to +5.5V. It delivers 10Ω max on-resistance at +5V, 1Ω max channel-to-channel on-resistance match, and rail-to-rail signal handling (V+ to GND). With 12ns turn-on and 10ns turn-off times, it serves in low-voltage audio routing and battery-powered data-acquisition front-ends.
For engineers reviewing the MAX4615CUD-TG068 datasheet, MAX4615CUD-TG068 pinout, MAX4615CUD-TG068 application, or MAX4615CUD-TG068 equivalent, key selection criteria include guaranteed NC switching behavior, sub-1nA off-leakage at +25°C, flat on-resistance over full signal range, and TTL/CMOS logic compatibility at +5V supply.
Technical Context
The MAX4615CUD-TG068 implements four independent NC analog switches using matched CMOS transmission-gate topology. Each switch features bidirectional conduction, 0V to V+ analog signal range, and logic-controlled inversion: low input enables conduction (ON), high input disables (OFF).
Its internal architecture ensures <1Ω on-resistance variation across channels and <1Ω flatness over the entire analog voltage range, enabling precision multiplexing without gain error. Off-isolation exceeds -85dB at 100kHz, and crosstalk remains below -96dB at 1MHz - critical for high-fidelity signal routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 10Ω max at +5V - ensures minimal signal attenuation and voltage drop in low-level analog paths |
| On-Resistance Match (∆RON) | 1Ω max - guarantees consistent gain and channel tracking in multi-path systems |
| On-Resistance Flatness | 1Ω max over full signal range - preserves linearity across 0V to V+ analog inputs |
| Off-Leakage Current | 1nA max at +25°C - prevents DC error accumulation in sample-and-hold or sensor interfaces |
| Switching Speed | tON = 12ns, tOFF = 10ns - supports high-speed multiplexing up to ~70MHz bandwidth |
| Analog Signal Range | Rail-to-rail (0V to V+) - enables full utilization of supply headroom without clipping |
| Logic Compatibility | VIN_H = 2.4V, VIN_L = 0.8V at +5V - ensures reliable interface with standard TTL/CMOS drivers |
Pinout & Package
MAX4615CUD-TG068 is housed in a 14-pin TSSOP package (3.0mm × 4.4mm, 0.65mm pitch) with exposed pad for thermal enhancement. Pin 1 is V+, pins 5/6/12/13 are digital control inputs (IN1–IN4), pins 2/4/9/10 are common terminals (COM1–COM4), and pins 1/3/8/11 are normally closed analog terminals (NC1–NC4).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ (Pin 14) | Positive supply rail | Must be applied before analog signals; powers internal CMOS switches and level-shifters |
| GND (Pin 7) | Reference ground | Return path for supply current and logic thresholds; must be low-impedance |
| IN1–IN4 (Pins 5,6,12,13) | Digital control inputs | Active-low logic: LOW = NC path closed, HIGH = NC path open |
| COM1–COM4 (Pins 2,4,9,10) | Common analog terminals | Bidirectional connection point shared between NC and signal path |
| NC1–NC4 (Pins 1,3,8,11) | Normally closed analog terminals | Conduct to COM when INx = LOW; open when INx = HIGH |
Key Features
| Feature | Design Value |
|---|---|
| Pin-compatible replacement | Direct drop-in for 74HC4066 and MAX4610 - no PCB redesign required |
| Rail-to-rail analog operation | Supports 0V to V+ signal swing - eliminates need for external biasing in single-supply systems |
| Guaranteed channel matching | 1Ω max RON mismatch - enables accurate differential or ratiometric measurements |
| Ultra-low off-leakage | <6nA at +85°C - maintains accuracy in high-impedance sensor or integrator circuits |
| Fast, low-jitter switching | 12ns tON / 10ns tOFF - minimizes timing uncertainty in synchronized sampling applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4615CSD | Same electrical specs; 14-pin narrow SO package (3.9mm × 8.7mm) | Larger footprint, higher thermal resistance (8.00mW/°C derating vs. 6.3mW/°C) | Select for legacy SO-based designs or where TSSOP reflow compatibility is unavailable |
| ADG1415YRUZ | 12Ω RON at +5V, ±15V dual-supply capable, 20ns tON/tOFF | Supports bipolar signals and higher voltage rails; slower switching than MAX4615CUD-TG068 | Choose when interfacing with ±12V op-amps or requiring extended analog range beyond V+ |
Compared with MAX4615CUD-TG068, MAX4615CSD offers identical performance in a larger SO package suited for manual assembly or thermal-limited environments, while ADG1415YRUZ trades speed and low-voltage optimization for bipolar rail flexibility - making MAX4615CUD-TG068 optimal for compact, battery-powered, single-supply precision routing.

FAQ
What is the maximum supply voltage rating for MAX4615CUD-TG068?
The absolute maximum supply voltage (V+) for MAX4615CUD-TG068 is +6V. Operation above this level risks permanent damage. The device is specified for reliable operation from +2V to +5.5V, with on-resistance and leakage parameters guaranteed across that range. Exceeding +6V violates Absolute Maximum Ratings and may compromise internal ESD protection structures.
Does MAX4615CUD-TG068 support rail-to-rail analog signal switching?
Yes, MAX4615CUD-TG068 supports true rail-to-rail analog signal handling: signals from 0V to V+ are passed without clipping or distortion. This is enabled by its CMOS transmission-gate architecture and is explicitly guaranteed in the datasheet under "Analog Signal Range" with VCOM_, VNC_ spanning 0V to V+. No external biasing is needed for single-supply systems.
What is the logic behavior of the control inputs on MAX4615CUD-TG068?
The control inputs (IN1–IN4) on MAX4615CUD-TG068 are active-low for NC operation: a logic LOW (≤0.8V) closes the NC switch (connects NCx to COMx), while a logic HIGH (≥2.4V at +5V supply) opens it. This behavior is fixed per the MAX4615 variant and differs from MAX4614 (NO) and MAX4616 (mixed). Input thresholds ensure TTL/CMOS compatibility.
How does MAX4615CUD-TG068 compare to the industry-standard 74HC4066?
MAX4615CUD-TG068 is pin-compatible with 74HC4066 but improves upon it with 10Ω max on-resistance (vs. ~50Ω typical for 74HC4066), 1Ω max channel matching (vs. unguaranteed), and <1nA off-leakage (vs. ~100nA). It also adds guaranteed flatness and rail-to-rail operation - making MAX4615CUD-TG068 suitable for precision, low-voltage applications where 74HC4066 falls short.
Is thermal performance affected by the TSSOP package of MAX4615CUD-TG068?
Yes - the 14-pin TSSOP package of MAX4615CUD-TG068 has a thermal derating factor of 6.3mW/°C above +70°C and a maximum continuous power dissipation of 500mW at +70°C. Its exposed pad enhances thermal conduction; proper PCB copper pour under the pad is recommended to maintain junction temperature within limits during sustained 75mA channel current operation.
