Product details
Overview
MAX4614EPD 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-designed for precision signal routing in battery-powered audio/video systems.
For engineers reviewing the MAX4614EPD datasheet, MAX4614EPD pinout, MAX4614EPD application, or MAX4614EPD equivalent, this device is evaluated for low-leakage switching in data-acquisition front-ends, sample-and-hold circuits, and communication channel multiplexing where matched on-resistance and minimal charge injection are critical.
Technical Context
The MAX4614EPD implements CMOS transmission-gate architecture with TTL/CMOS-compatible digital inputs (0.8V/2.4V thresholds), enabling direct interface with +5V microcontrollers without level shifting. Its four independent NO switches operate from a single +2V to +5.5V supply, supporting rail-to-rail analog signals up to V+.
On-resistance matching (≤1Ω max between channels) and flatness (≤1Ω max over full signal range) ensure consistent gain and minimal crosstalk in multi-channel routing. Off-leakage remains ≤6nA at +85°C, preserving accuracy in high-impedance sampling nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V - supports Li-ion battery (3.0–3.7V) and USB-powered systems without regulation. |
| On-Resistance (max) | 10Ω at +5V - ensures <0.1% gain error in 1kΩ signal paths; rises to 20Ω at +3V. |
| On-Resistance Match | ≤1Ω max between channels - enables precise ratio-metric signal routing in instrumentation amps. |
| Turn-On / Turn-Off Time | 12ns / 10ns at +5V - supports >50MHz switching in high-speed multiplexed ADC drivers. |
| Off-Leakage Current | ≤6nA at TA = +85°C - maintains <1LSB error in 16-bit, 1MΩ-input SAR ADC sample-and-hold stages. |
| Signal Range | V+ to GND - allows unipolar sensor outputs (e.g., 0–3.3V thermistor bridges) to pass without clipping. |
| Logic Compatibility | TTL/CMOS thresholds (0.8V low / 2.4V high) - interoperable with standard +5V MCUs and FPGAs. |
Pinout & Package
MAX4614EPD uses a 14-pin plastic DIP package (0.300" wide), rated for -40°C to +85°C operation, with through-hole mounting and 800mW power dissipation at +70°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NO1–NO4 | Normally open analog terminals - connect only when corresponding INx is HIGH; bidirectional signal path. |
| 2, 4, 9, 10 | COM1–COM4 | Common analog terminals - serve as input/output junctions for each SPST switch; rail-to-rail capable. |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - TTL/CMOS compatible; drive internal gate logic to close respective NO switch. |
| 7 | GND | Analog/digital ground reference - must be low-impedance; shared return for all COM/NO paths. |
| 14 | V+ | Positive supply - powers analog switch core and input buffers; decoupling capacitor required at pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from GND to V+ without clamping - eliminates need for external level shifters in 0–V+ sensor interfaces. |
| Matched on-resistance (≤1Ω) | Enables simultaneous switching of differential pairs or multi-channel gain blocks with <0.1% mismatch-induced offset. |
| Low charge injection (6.5pC) | Minimizes voltage glitch on high-impedance hold capacitors - critical for sub-12-bit accuracy in sample-and-hold circuits. |
| Pin compatibility with 74HC4066/MAX4610 | Direct drop-in replacement in legacy designs - no PCB layout changes needed for upgrade to lower leakage and faster timing. |
| Guaranteed flat on-resistance | ≤1Ω variation across full 0–V+ signal swing - preserves linearity in precision attenuator and programmable-gain amplifier applications. |

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 |
|---|---|---|---|
| MAX4614EUD | Same electrical specs, but in 14-pin TSSOP (3.0mm × 4.4mm) - 60% smaller footprint, surface-mount only. | Suitable for space-constrained PCBs; thermal resistance higher (6.3mW/°C derating vs. 10mW/°C for DIP). | Select MAX4614EUD when board area is limited and reflow assembly is available; MAX4614EPD preferred for prototyping or through-hole production. |
| ADG1414BRUZ | 4-channel SPST, 1.5Ω typical RON, ±15V dual-supply capable; higher cost, larger 16-TSSOP package. | Designed for ±5V/±12V industrial signal chains; not pin-compatible; requires level-shifting for +5V logic control. | Choose ADG1414BRUZ only when bipolar supply operation or sub-2Ω RON is mandatory; MAX4614EPD remains optimal for unipolar, low-cost, +5V systems. |
Compared with MAX4614EUD, MAX4614EPD offers easier manual soldering and better thermal dissipation (800mW vs. 500mW), while ADG1414BRUZ trades pin compatibility and cost for superior on-resistance and dual-supply flexibility - making MAX4614EPD the balanced choice for robust, field-serviceable, low-voltage analog routing.

FAQ
What is the maximum supply voltage rating for MAX4614EPD?
The absolute maximum supply voltage for MAX4614EPD is +6V, but the recommended operating range is +2V to +5.5V. Exceeding +6V risks permanent damage due to internal ESD diode breakdown. At +5.5V, on-resistance remains within spec (≤10Ω), and logic thresholds stay stable. Always observe the -0.3V to +6V limit on V+ and analog pins relative to GND.
Does MAX4614EPD support bidirectional analog signal flow?
Yes, MAX4614EPD supports fully bidirectional analog signal flow on all NO and COM terminals. Each SPST switch operates identically regardless of signal direction - enabling use in both source-to-load and load-to-source configurations. This is inherent to its CMOS transmission-gate design and rail-to-rail voltage handling (GND to V+).
How does temperature affect off-leakage current in MAX4614EPD?
MAX4614EPD guarantees ≤6nA off-leakage current at TA = +85°C, rising from ≤1nA at +25°C. This increase is linear and predictable, verified across the full -40°C to +85°C range. In high-impedance sample-and-hold applications, this leakage contributes <1mV drift over 10ms on a 10nF capacitor at +85°C - a key design constraint for 14-bit+ systems.
Is MAX4614EPD pin-compatible with the 74HC4066?
Yes, MAX4614EPD is explicitly designed as a pin-compatible upgrade to the industry-standard 74HC4066. Pin assignments for V+, GND, COMx, NOx, and INx match exactly in the 14-pin DIP package. Unlike the 74HC4066, MAX4614EPD offers guaranteed 10Ω RON, lower leakage, and faster switching - with no PCB changes required.
What is the typical charge injection value for MAX4614EPD, and why does it matter?
MAX4614EPD has a typical charge injection of 6.5pC, measured at V+ = +5V and TA = +25°C. This parameter quantifies the net charge dumped onto the COM node during switching, directly causing voltage glitches on hold capacitors. In a 10nF sample-and-hold circuit, 6.5pC induces a 0.65mV step - limiting achievable resolution unless compensated via aperture timing or capacitor sizing.
