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, 12ns max turn-off time, and ±300mA continuous current handling in a 5-pin SC70 package - used for power routing and audio signal switching in battery-powered portable devices.
For engineers reviewing the MAX4716EXK-T datasheet, MAX4716EXK-T pinout, MAX4716EXK-T application, or MAX4716EXK-T equivalent, key selection criteria include NC default state, sub-0.5Ω RON at 3V, CMOS-compatible logic inputs, fast 12ns/18ns switching, and SC70-5 footprint compatibility with MAX4595.
Technical Context
The MAX4716EXK-T implements a CMOS-based SPST analog switch with bidirectional signal path capability and rail-to-rail analog voltage support (GND to V+). Its NC configuration ensures COM–NC continuity when IN = 0V, breaking only upon logic-high activation.
It features guaranteed RON flatness of ≤0.1Ω over the full analog range at +3V, <10nA leakage across all terminals (COM, NO, NC) over –40°C to +85°C, and charge injection of 20pC typical - enabling precision low-distortion signal routing in data-acquisition and audio paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 0.4Ω max at +3V supply - enables <10mV drop at 25mA, critical for low-voltage power routing |
| RON Flatness | 0.1Ω max at +3V - ensures consistent gain/attenuation across 0–3V analog signals |
| Turn-Off Time (tOFF) | 12ns max - supports >30MHz switching in high-speed multiplexing applications |
| Analog Signal Range | GND to V+ - allows full-supply-range signal pass-through without clipping |
| Logic Compatibility | +1.8V CMOS compatible at +3V supply - interfaces directly with 1.8V/3.3V microcontrollers |
| Operating Temperature | –40°C to +85°C - qualified for industrial and consumer portable equipment environments |
| Supply Voltage Range | +1.6V to +3.6V - supports single-cell Li-ion (3.0–3.6V) and dual-cell NiMH (2.4–3.0V) systems |
Pinout & Package
MAX4716EXK-T is housed in a 5-pin SC70 package (2.0mm × 1.25mm × 0.95mm height), RoHS-compliant with lead-free finish per package variant X5-1*.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - COM | Analog common terminal | Bidirectional node connected to NC by default; serves as input/output for routed signal path |
| 2 - NO | Normally open terminal | Open-circuit when IN = 0V; isolated from COM unless activated - unused in NC operation |
| 3 - GND | Ground reference | Return path for supply and logic; must be low-impedance to minimize RON variation and THD |
| 4 - V+ | Positive supply input | Single supply rail (1.6–3.6V); powers internal CMOS switch core and level-shifting circuitry |
| 5 - IN | Digital control input | Active-high logic: IN = 0V maintains NC closure; IN ≥1.4V opens NC–COM path |
Key Features
| Feature | Design Value |
|---|---|
| Normally closed (NC) default state | Ensures fail-safe signal continuity during power-up, reset, or MCU initialization |
| 0.4Ω max RON at +3V | Minimizes insertion loss and self-heating in 300mA power-switching paths |
| 0.1Ω max RON flatness | Maintains linearity for audio and sensor signals across full 0–3V range |
| 12ns max tOFF / 18ns max tON | Enables time-critical sampling and channel hopping in portable data loggers |
| +1.8V CMOS logic compatibility | Eliminates level-shifters when interfacing with 1.8V I/O microcontrollers |
Applications
| Power Routing | Audio Signal Switching |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4595EXK-T | Identical pinout, same NC function, identical RON/tOFF specs; newer revision with enhanced ESD rating (±2kV HBM) | Preferred for new designs requiring higher robustness in manufacturing handling or field environments | Select MAX4595EXK-T if ESD immunity >2kV HBM is required; otherwise MAX4716EXK-T remains fully functional |
| TMUX1574RSE | 4-channel SPDT, 0.5Ω RON, +1.08V to +3.6V supply; not pin-compatible; requires PCB redesign | Suitable for multi-signal routing where channel count >1 is needed, but adds complexity for single-path use | Choose TMUX1574RSE only when expanding to 4-channel switching; MAX4716EXK-T is optimal for minimal single-NC replacement |
Compared with MAX4595EXK-T, the MAX4716EXK-T offers identical functionality with slightly lower ESD rating but broader legacy qualification; versus TMUX1574RSE, it provides simpler integration, smaller footprint, and lower cost for single-NC applications - making it ideal for space-constrained, cost-sensitive portable designs.

FAQ
What is the default connection state of the MAX4716EXK-T when unpowered or with IN = 0V?
The MAX4716EXK-T is a normally closed (NC) switch: COM and NC terminals are conductive when IN = 0V or the device is unpowered, ensuring fail-safe continuity. This behavior is inherent to its internal CMOS topology and does not require external biasing. The MAX4716EXK-T maintains this NC state across its full –40°C to +85°C operating range and down to 1.6V supply.
Can the MAX4716EXK-T operate with a 1.8V supply, and what is its on-resistance under that condition?
Yes, the MAX4716EXK-T operates across +1.6V to +3.6V, including 1.8V. At +1.8V supply and 10mA load, its on-resistance is 1.2Ω max (typical 0.6Ω), per Electrical Characteristics table. While higher than the 0.4Ω max at +3V, this remains suitable for low-current signal routing and logic-level translation where voltage headroom is constrained.
Is the MAX4716EXK-T pin-compatible with any other Maxim analog switches?
Yes - the MAX4716EXK-T is explicitly pin-compatible with the MAX4595EXK-T, sharing identical SC70-5 pinout, terminal functions, and NC configuration. Both devices support the same supply range, logic thresholds, and dynamic performance. This allows direct substitution in existing layouts without PCB modification, provided ESD requirements align.
What is the maximum continuous current the MAX4716EXK-T can handle, and how is it limited?
The MAX4716EXK-T supports ±300mA continuous current between COM and NC (or NO, if used), limited by on-resistance heating and package thermal resistance. At 0.4Ω RON and 300mA, power dissipation is 36mW - well within the 247mW derated limit for SC70-5 at +70°C ambient. Peak pulsed current is ±600mA (1ms, 10% duty cycle).
Does the MAX4716EXK-T support bidirectional analog signal flow, and what is the impact on THD?
Yes, the MAX4716EXK-T is fully bidirectional: COM, NC, and NO may serve as input or output. Total harmonic distortion is specified at 0.01% typical (20Hz–20kHz, 2VP-P, 32Ω load), enabled by low RON flatness (≤0.1Ω) and symmetric CMOS structure. This makes the MAX4716EXK-T suitable for both audio playback and recording paths without polarity-dependent performance degradation.
