Product details
Overview
MAX4716EXK+T from Maxim Integrated is a normally closed (NC), low-voltage, single-pole/single-throw (SPST) analog switch operating from +1.6V to +3.6V supply, delivering 0.4Ω max on-resistance at +3V, 18ns max turn-on time, and SC70-5 package for space-constrained battery-powered audio routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4716EXK+T datasheet, MAX4716EXK+T pinout, MAX4716EXK+T application, or MAX4716EXK+T equivalent, key selection criteria include NC default state, rail-to-rail analog signal handling (0V to V+), +1.8V CMOS logic compatibility at +3V supply, and guaranteed RON flatness of ≤0.1Ω across signal range.
Technical Context
The MAX4716EXK+T implements a CMOS transmission-gate architecture optimized for low-voltage operation, with bidirectional analog signal paths supporting full rail-to-rail input/output swing (0V to V+). Its logic control input tolerates up to +3.6V regardless of supply voltage, enabling interfacing with higher-voltage controllers without level-shifting.
Internal ESD protection and clamping diodes allow safe operation with analog signals exceeding V+ or GND by up to 0.3V. The device guarantees ±300mA continuous current handling and supports pulsed peak currents up to ±600mA at 10% duty cycle, making it suitable for power routing in portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 0.4Ω max at +3V supply - enables low-loss signal switching with minimal voltage drop under 100mA load |
| RON Flatness | 0.1Ω max at +3V - ensures consistent channel resistance across full 0V–V+ analog signal range |
| Turn-On/Off Time | tON = 18ns max, tOFF = 12ns max - supports high-speed multiplexing in audio and data-acquisition paths |
| Analog Signal Range | 0V to V+ - allows rail-to-rail signal pass-through without clipping or distortion |
| Logic Compatibility | +1.8V CMOS compatible at +3V supply - interfaces directly with standard low-voltage microcontrollers |
| Supply Voltage Range | +1.6V to +3.6V - supports operation across Li-ion, Li-poly, and dual-cell alkaline battery configurations |
| Off-Leakage Current | ±10nA max over –40°C to +85°C - preserves signal integrity in high-impedance sensor and precision measurement circuits |
Pinout & Package
The MAX4716EXK+T is housed in a 5-pin SC70-5 package (Outline 21-0076), RoHS-compliant, with 0.65mm pitch and footprint-compatible with industry-standard SC70 land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - COM | Analog Switch Common Terminal | Bidirectional signal path shared between NC and internal switch; connects to load or source depending on routing topology |
| 2 - NC | Normally Closed Analog Terminal | Internally connected to COM when IN = logic low; provides default continuity without active control |
| 3 - GND | Ground Reference | Analog and digital ground reference; must be low-impedance connection to minimize noise coupling into analog path |
| 4 - IN | Digital Control Input | CMOS-compatible logic input; drives switch open (disconnection) when high (≥1.4V at +3V supply) |
| 5 - V+ | Positive Supply Input | Single supply rail; powers internal circuitry and defines analog signal range (0V to V+) |
Key Features
| Feature | Design Value |
|---|---|
| Normally Closed Default State | Ensures fail-safe continuity in power routing or safety-critical signal paths when control power is absent |
| Rail-to-Rail Analog Operation | Supports full-swing audio, sensor, and data signals without headroom loss or distortion at supply extremes |
| Low Charge Injection (20pC) | Minimizes transient glitches during switching in sample-and-hold and precision ADC front-end applications |
| High Off-Isolation (–54dB @ 1MHz) | Effectively blocks crosstalk between channels in multi-source audio/video routing and communications circuits |
| Ultra-Low Supply Current (0.2µA max) | Extends battery life in always-on or low-duty-cycle portable equipment such as modems and cellular handsets |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4595EUK+T | Same SC70-5 package, identical pinout, but specified for –40°C to +125°C operation and higher RON (0.5Ω max at +3V) | Targeted at extended-temperature industrial and automotive modules where wider thermal range is required | Select MAX4595EUK+T when operating beyond +85°C or requiring AEC-Q100 qualification support |
| TMUX1574DSGR | 4-channel SPDT, 0.5Ω RON, +1.08V to +3.6V supply, but not NC-default and requires separate enable per channel | Suitable for multi-channel routing where density and flexible channel control outweigh NC requirement | Choose TMUX1574DSGR only when consolidating multiple switches onto one die and accepting active-high enable logic |
Compared with MAX4716EXK+T, MAX4595EUK+T offers extended temperature capability at slightly higher RON, while TMUX1574DSGR trades NC default behavior for multi-channel integration-neither is pin-compatible nor functionally identical, but both serve adjacent low-voltage analog routing needs.

FAQ
What is the default switch state of the MAX4716EXK+T?
The MAX4716EXK+T is a normally closed (NC) analog switch: when the IN pin is logic low (≤0.5V at +3V supply), the internal path between NC and COM remains conductive. It opens only when IN is driven high (≥1.4V). This fail-safe behavior ensures continuity in power routing or critical signal paths during power-up or controller reset-distinct from the MAX4715EXK+T's normally open configuration.
Does the MAX4716EXK+T support rail-to-rail analog signals?
Yes, the MAX4716EXK+T supports analog signals from 0V to V+ (e.g., 0V to +3.3V) with minimal RON variation. At +3V supply, RON flatness is guaranteed ≤0.1Ω across the full voltage range, enabling distortion-free audio and precision sensor signal routing without clipping or gain error-critical for line-level audio and DC-coupled data acquisition.
What is the maximum continuous current rating for the MAX4716EXK+T?
The MAX4716EXK+T supports ±300mA continuous current between NC and COM terminals at ambient temperatures up to +70°C. Derating applies above +70°C (247mW max at TA = +70°C, derated 3.1mW/°C). This rating enables reliable use in power-path switching for peripherals, backup batteries, and low-power subsystems without external current-limiting components.
Can the MAX4716EXK+T logic input be driven above its supply voltage?
Yes-the IN pin of the MAX4716EXK+T is overvoltage-tolerant up to +3.6V regardless of V+ supply level (which ranges from +1.6V to +3.6V). For example, with V+ = +1.8V, IN may still be driven to +3.3V or +3.6V. This eliminates level shifters when interfacing with higher-voltage microcontrollers or FPGAs, simplifying system design and reducing BOM count.
How does the MAX4716EXK+T handle ESD and overvoltage on analog pins?
The MAX4716EXK+T integrates internal ESD protection diodes on NO, NC, and COM pins, clamping signals that exceed V+ or GND by more than ±0.3V. This protects against transient overvoltage events common in hot-plug interfaces and noisy environments. Absolute maximum ratings specify –0.3V to (V+ + 0.3V) for these pins, ensuring robust operation in PCMCIA, modem, and portable communication circuits without external TVS devices.
