Product details
Overview
MAX4614CUD from Analog Devices is a quad, low-voltage, high-speed SPST analog switch with four normally open (NO) channels, 10Ω max on-resistance at +5V, 12ns turn-on time, and rail-to-rail signal handling from V+ to GND-used in battery-powered audio routing and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4614CUD datasheet, MAX4614CUD pinout, MAX4614CUD application, or MAX4614CUD equivalent, this page delivers verified electrical specs, TSSOP-14 pin mapping, real-world use cases in signal switching, and two validated alternative parts for design flexibility under 5.5V supply constraints.
Technical Context
The MAX4614CUD implements CMOS transmission-gate architecture with matched channel on-resistance (≤1Ω max mismatch) and flat on-resistance profile (≤1Ω variation over full 0V to V+ signal range), enabling precision multiplexing without gain error. Its TTL/CMOS-compatible logic inputs (0.8V/2.4V thresholds at +5V) support direct interfacing with microcontrollers and FPGAs.
Each NO switch operates bidirectionally between COM and NO terminals, supports ±75mA continuous current, and maintains <6nA off-leakage at +85°C-critical for high-impedance sample-and-hold and sensor interface circuits where leakage-induced voltage drift must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V - enables operation from single Li-ion cell (3.0–3.7V) or regulated 3.3V/5V rails without level-shifting. |
| On-Resistance (max) | 10Ω at +5V - ensures ≤0.1% gain error in 1kΩ impedance signal paths; matched within 1Ω across all four switches. |
| Switching Speed | tON = 12ns, tOFF = 10ns - supports >20MHz digital signal routing and fast multiplexed ADC sampling. |
| Off-Leakage Current | 6nA at TA = +85°C - preserves charge integrity in >100MΩ hold capacitors for ≥10ms sampling intervals. |
| Analog Signal Range | 0V to V+ - allows rail-to-rail input/output swing without clipping in unipolar sensor or DAC output stages. |
| Logic Compatibility | TTL/CMOS thresholds (VIN_L = 0.8V, VIN_H = 2.4V @ +5V) - eliminates need for external logic translators when driven by standard MCU GPIOs. |
| Bandwidth | 70MHz - supports composite video, USB 1.1 signaling, and baseband audio without attenuation. |
Pinout & Package
MAX4614CUD is housed in a 14-pin TSSOP package (4.4mm × 5mm, 0.65mm pitch), optimized for space-constrained portable designs and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NO1–NO4 | Normally open analog switch terminals - connect only when corresponding INx is HIGH; bidirectional signal path. |
| 2, 4, 9, 10 | COM1–COM4 | Common analog node per switch - serves as input or output depending on signal direction; handles full V+ to GND range. |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - active-HIGH logic; drive internal gate of each NO switch; TTL/CMOS compatible. |
| 7 | GND | Analog and digital reference ground - must be low-impedance connection to minimize crosstalk and offset. |
| 14 | V+ | Positive supply - powers analog switch core and input buffers; decoupling capacitor (0.1µF) required adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports 0V to V+ analog signals without clamping or distortion - essential for unipolar sensor outputs and DAC interfaces. |
| Matched on-resistance | ≤1Ω max difference between any two channels - enables precise ratio-metric measurements in multi-channel instrumentation. |
| Low charge injection | 6.5pC - minimizes voltage glitch on hold capacitors during switching, critical for 12-bit+ SAR ADC front-ends. |
| High off-isolation | −85dB at 100kHz - suppresses crosstalk between active and inactive channels in dense multiplexer layouts. |
| Ultra-low power consumption | 1µA max supply current - extends battery life in always-on monitoring systems with periodic switching. |

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 |
|---|---|---|---|
| MAX4615CUD | Four normally closed (NC) switches instead of NO; identical pinout, timing, and on-resistance specs. | Used where default-closed signal path is required (e.g., fail-safe sensor disconnect). | Select MAX4615CUD only when NC behavior is functionally required; not drop-in for NO logic. |
| ADG1414BRUZ | Higher on-resistance (1.8Ω typ at +5V), wider supply (±5V or +5V to +16.5V), LFCSP-16 package. | Suitable for higher-voltage industrial I/O modules but requires PCB layout change and has 20% higher RON mismatch. | Choose ADG1414BRUZ only when bipolar supply or >5.5V operation is needed; not pin-compatible. |
Compared with MAX4614CUD, MAX4615CUD offers identical performance in an NC configuration for safety-critical default-closed paths, while ADG1414BRUZ extends voltage range at the cost of increased on-resistance mismatch and non-compatible packaging-making MAX4614CUD optimal for compact, low-voltage, NO-switching applications.

FAQ
What is the maximum supply voltage rating for MAX4614CUD?
The absolute maximum supply voltage for MAX4614CUD is +6V, but the recommended operating range is +2V to +5.5V. Exceeding +5.5V risks permanent damage and violates the guaranteed on-resistance and leakage specifications documented in the Analog Devices datasheet. Operation at +5.5V is allowed only with proper derating and thermal management.
Does MAX4614CUD support bidirectional analog signal flow?
Yes, MAX4614CUD supports fully bidirectional signal flow between COM and NO terminals. Each of its four SPST switches functions identically in either direction, with matched on-resistance and flatness over the full 0V to V+ range-enabling flexible routing in both source-to-load and load-to-source configurations without polarity constraints.
Can MAX4614CUD operate from a 3.3V supply while maintaining specified performance?
Yes, MAX4614CUD operates reliably at +3.3V with guaranteed 20Ω max on-resistance, 15ns max tON, and <10nA off-leakage at +85°C. The device's TTL/CMOS logic thresholds (VIN_L = 0.8V, VIN_H = 2.0V at +3.3V) ensure compatibility with standard 3.3V microcontrollers without level shifters.
What is the thermal performance limit for continuous operation of MAX4614CUD?
MAX4614CUD is rated for continuous operation from 0°C to +70°C (commercial grade). Its 14-pin TSSOP package has a thermal resistance θJA of 158°C/W; at 500mW max power dissipation, junction temperature remains within safe limits only if ambient stays below +55°C with adequate PCB copper area and airflow.
Is MAX4614CUD pin-compatible with the 74HC4066?
Yes, MAX4614CUD is explicitly pin-compatible with the industry-standard 74HC4066 and MAX4610, sharing identical 14-pin TSSOP pinout, logic input behavior, and COM/NO terminal assignments. This allows direct replacement in legacy designs without PCB modification, provided supply voltage and signal range requirements align.
