Product details
Overview
MAX4614CUD-T from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally open (NO) CMOS analog switch operating from a single +2V to +5.5V supply. It delivers 10Ω max on-resistance at +5V, 12ns turn-on time, rail-to-rail signal handling (V+ to GND), <6nA off-leakage at +85°C, and TTL/CMOS logic compatibility-enabling precision signal routing in low-voltage battery-powered audio multiplexers.
For engineers reviewing the MAX4614CUD-T datasheet, MAX4614CUD-T pinout, MAX4614CUD-T application, or MAX4614CUD-T equivalent, key selection criteria include guaranteed on-resistance matching (≤1Ω), flatness over signal range (≤1Ω), charge injection (6.5pC), off-isolation (−85dB), and TSSOP-14 package compatibility with 74HC4066/MAX4610 footprints.
Technical Context
The MAX4614CUD-T implements four independent SPST NO switches using complementary CMOS transistor pairs per channel, enabling bidirectional analog signal conduction with minimal distortion. Its logic inputs accept 0.8V/2.4V thresholds for reliable TTL/CMOS interfacing at +5V supply, and internal level-shifting ensures consistent switching behavior across the full +2V to +5.5V operating range.
Each switch supports rail-to-rail analog voltages (GND to V+), with on-resistance flatness ≤1Ω and channel-to-channel matching ≤1Ω-critical for instrumentation-grade multiplexing where gain or offset errors must be minimized. Off-isolation exceeds −85dB at 100kHz, and crosstalk remains below −96dB at 1MHz, supporting high-fidelity signal integrity in mixed-signal systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V - enables direct integration into Li-ion, 3.3V, and 5V systems without level shifters. |
| On-Resistance (max) | 10Ω at +5V - ensures ≤0.5% gain error in 2kΩ sensor interface paths. |
| On-Resistance Match | ≤1Ω max between channels - maintains channel balance in differential or ratiometric measurements. |
| Turn-On / Turn-Off Time | 12ns / 10ns - supports >30MHz digital control of analog signals in fast data acquisition. |
| Off-Leakage Current | 6nA at +85°C - limits voltage error to <6µV in 1MΩ high-impedance sample-and-hold nodes. |
| Charge Injection | 6.5pC - restricts sampling glitch to <1LSB in 12-bit 1V-range ADC front-ends. |
| Off-Isolation | −85dB at 100kHz - suppresses crosstalk between adjacent audio or sensor channels. |
Pinout & Package
MAX4614CUD-T is housed in a 14-pin TSSOP (Thin Shrink Small Outline Package) with 0.65mm lead pitch, JEDEC MO-153 compliant, and rated for 0°C to +70°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply rail | Accepts +2V to +5.5V; powers all four analog switches and logic interface. |
| GND | Ground reference | Return path for supply current and logic/switch reference; must be low-impedance. |
| IN1–IN4 | Digital control inputs | TTL/CMOS-compatible; LOW = switch open, HIGH = switch closed (NO configuration). |
| COM1–COM4 | Analog common terminals | Bidirectional signal path entry points; connect to source or load depending on routing topology. |
| NO1–NO4 | Analog normally open terminals | Bidirectional signal path exit points; conduct only when corresponding INx is HIGH. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full GND-to-V+ signal swing without clipping or distortion in sensor or audio paths. |
| Guaranteed on-resistance flatness | ≤1Ω variation over entire signal range - eliminates amplitude-dependent nonlinearity in precision gain stages. |
| Low charge injection (6.5pC) | Minimizes sampling transient in switched-capacitor circuits and ADC sample-hold networks. |
| High off-isolation (−85dB) | Prevents signal bleed between inactive channels in multi-source audio or data-acquisition systems. |
| Pin compatibility with 74HC4066/MAX4610 | Enables drop-in replacement in legacy designs without PCB layout changes or firmware updates. |
Applications
| Audio Signal Multiplexer | Portable Data Acquisition Front-End |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4610EUD+T | Same pinout, but higher on-resistance (15Ω max at +5V) and slower switching (25ns tON). | Targeted at cost-sensitive industrial controls where speed and RON tolerance are relaxed. | Select MAX4610EUD+T only if design can tolerate ≥2× higher on-resistance and 2× longer switching latency. |
| ADG1414BRUZ | 16-pin TSSOP, 4.5Ω max RON at +5V, but requires dual supplies (±15V or +12V/−5V) or special biasing for rail-to-rail operation. | Used in high-precision test equipment where ultra-low RON and THD (<0.002%) are mandatory. | Choose ADG1414BRUZ only when lower on-resistance and distortion outweigh footprint and supply complexity penalties. |
Compared with MAX4614CUD-T, MAX4610EUD+T trades performance for cost in less demanding analog routing, while ADG1414BRUZ delivers superior RON and linearity at the expense of dual-supply support and larger package-making MAX4614CUD-T optimal for compact, single-supply, battery-operated systems needing balanced speed, leakage, and integration.

FAQ
What is the maximum supply voltage rating for MAX4614CUD-T?
The MAX4614CUD-T has an absolute maximum supply voltage (V+) of +6V. Operation above this level risks permanent damage. The recommended operating range is +2V to +5.5V, with guaranteed performance including 10Ω max on-resistance and 12ns tON within that window. Exceeding +6V-even briefly-can trigger internal diode clamping and degrade long-term reliability.
Does MAX4614CUD-T support rail-to-rail analog signal operation?
Yes, MAX4614CUD-T supports true rail-to-rail analog signal handling: signals from GND to V+ pass through the switch with no clipping or distortion. This is confirmed in the datasheet's "Analog Signal Range" specification (0V to V+), and validated by its CMOS transmission-gate architecture. The feature enables direct interfacing with op-amps, ADCs, and sensors operating at supply rails without external level-shifting circuitry.
What is the logic threshold compatibility of MAX4614CUD-T at +5V supply?
At +5V supply, MAX4614CUD-T guarantees TTL/CMOS logic compatibility with input voltage thresholds of +0.8V (VIN_L) and +2.4V (VIN_H). These thresholds ensure robust recognition of standard 5V logic levels from microcontrollers, FPGAs, or logic gates-no external pull-ups or level translators required. Input currents remain under ±10nA across temperature, minimizing loading on driving sources.
Can MAX4614CUD-T be used in sample-and-hold circuits?
Yes, MAX4614CUD-T is well-suited for sample-and-hold circuits due to its low 6.5pC charge injection and <6nA off-leakage at +85°C. These parameters directly limit sampling glitch amplitude and hold-node voltage droop-critical for maintaining accuracy in 12-bit ADC front-ends. The 12ns tON also enables precise timing control of acquisition windows without introducing aperture uncertainty.
Is MAX4614CUD-T pin-compatible with the 74HC4066?
Yes, MAX4614CUD-T is explicitly designed as a pin-compatible upgrade to the industry-standard 74HC4066. Both share identical 14-pin TSSOP/SO/DIP pinouts, NO switch configuration, and logic polarity (HIGH = ON). However, MAX4614CUD-T improves on-resistance (10Ω vs. ~60Ω), leakage (<6nA vs. ~100nA), and speed (12ns vs. ~40ns), making it a direct functional and physical replacement in existing layouts.
