Product details
Overview
MAX4687EBT-T from Maxim Integrated is a single-pole/single-throw (SPST) normally closed (NC) analog switch optimized for low-voltage, high-fidelity signal routing. It operates from +1.8V to +5.5V, delivers 2.5Ω max on-resistance at +3V, 0.4Ω max RON matching, and 30ns max turn-on time-enabling precision audio, battery-powered sensor multiplexing, and power-path control in space-constrained portable electronics.
For engineers reviewing the MAX4687EBT-T datasheet, MAX4687EBT-T pinout, MAX4687EBT-T application, or MAX4687EBT-T equivalent, key selection criteria include guaranteed NC default state, rail-to-rail analog signal handling (0V to V+), ultra-low leakage (<1nA at +25°C), UCSP-6 package footprint (1.50mm × 1.02mm), and 1.8V logic compatibility with +2.7V to +3.3V supplies.
Technical Context
The MAX4687EBT-T implements a CMOS transmission-gate architecture with matched P/N channel pairs to achieve flat on-resistance over its full analog signal range (0V to V+). Its digital control input accepts 1.8V logic thresholds (VIH = 1.4V, VIL = 0.5V) independent of supply voltage, enabling direct interfacing with low-voltage microcontrollers without level shifting.
Designed for bidirectional signal flow, the device supports rail-to-rail analog voltages while maintaining <1Ω RON flatness and −90dB off-isolation at 100kHz. Internal protection diodes clamp analog inputs to V+ + 0.3V, permitting safe operation under transient overvoltage conditions when external current limiting is applied.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +1.8V to +5.5V single supply - enables direct integration into Li-ion (3.0–3.7V) and dual-cell alkaline (2.4–3.2V) systems without regulators |
| RON (max) | 2.5Ω at +3V - ensures minimal signal attenuation and distortion in audio and sensor front-end paths |
| RON Matching | 0.4Ω max between channels - critical for balanced differential switching and precision instrumentation multiplexing |
| Turn-On/Off Time | tON = 30ns, tOFF = 12ns max - supports high-speed data acquisition and dynamic signal path reconfiguration |
| Off-Leakage Current | ±1nA max at TA = −40°C to +85°C - preserves accuracy in high-impedance sensor nodes and battery-monitoring circuits |
| Logic Compatibility | 1.8V logic input thresholds - allows direct drive from ARM Cortex-M0+/M3 GPIOs and other ultra-low-power MCUs |
| Off-Isolation | −90dB at 100kHz - suppresses crosstalk between adjacent signal paths in multi-channel audio/video routers |
Pinout & Package
The MAX4687EBT-T is housed in a 6-bump, 0.5mm pitch wafer-level chip-scale package (UCSP-6), occupying only 1.50mm × 1.02mm PCB area. The package uses solder bumps arranged in a 3×2 array and is qualified per JEDEC J-STD-020A reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B1 | V+ | Positive supply input - must be powered before analog signals to prevent latch-up; absolute max +6V |
| B2 | IN | Digital control input - active-high logic; drives internal gate bias; tolerant to 0V–5.5V swing regardless of V+ |
| B3 | GND | Analog/digital ground reference - requires low-impedance connection to minimize noise coupling into analog paths |
| A1 | NC | Normally closed analog terminal - conducts to COM when IN = low; open-circuit when IN = high |
| A3 | COM | Common analog terminal - bidirectional node connecting to NC (default) or NO (when enabled); handles rail-to-rail signals |
| A2 | I.C. | Internally connected bump - no external connection required; must be left floating or tied to GND per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Normally Closed Default State | Ensures fail-safe signal continuity during power loss or MCU reset - critical for battery monitoring and safety-critical power routing |
| Rail-to-Rail Signal Handling | Supports analog inputs from 0V to V+ without clipping - preserves full dynamic range in audio codecs and ADC front-ends |
| Ultra-Low Charge Injection (40pC) | Minimizes voltage glitches at COM during switching - essential for precision sample-and-hold and low-noise sensor interfaces |
| −95dB Crosstalk (MAX4688 only) | Not applicable to MAX4687EBT-T - this feature belongs exclusively to the SPDT variant MAX4688 and is excluded per scope rule #7 |
| Break-Before-Make Timing | Not applicable to MAX4687EBT-T - guaranteed only for MAX4688 SPDT; MAX4687 is SPST NC and has no BBM requirement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4686EBT-T | SPST NO configuration (open-circuit default); identical RON, timing, and package | Used where signal path must be interrupted on power loss (e.g., safety interlocks) | Select MAX4686EBT-T when fail-open behavior is required; MAX4687EBT-T is preferred for fail-safe continuity |
| TMUX1574DSGR | SPST NC, 3.5Ω RON at 3V, 1.8V logic compatible, 6-pin WSON package (1.5mm × 1.5mm) | Higher RON and larger footprint; lacks UCSP thermal performance for high-density layouts | Choose TMUX1574DSGR if WSON assembly infrastructure exists and 1Ω higher RON is acceptable in target signal chain |
Compared with MAX4686EBT-T, the MAX4687EBT-T provides complementary fail-safe behavior; compared with TMUX1574DSGR, it offers lower RON, smaller footprint, and superior thermal resistance in ultra-thin portable designs.

FAQ
What is the default state of the MAX4687EBT-T analog switch?
The MAX4687EBT-T is a normally closed (NC) SPST analog switch: when the IN pin is logic low (≤0.5V), the NC and COM terminals are conductive; when IN is high (≥1.4V), the path opens. This fail-safe default ensures signal continuity during power-down or MCU initialization, making MAX4687EBT-T ideal for battery monitoring and safety-critical power routing where uninterrupted sensing is required.
Does the MAX4687EBT-T support rail-to-rail analog signals?
Yes, the MAX4687EBT-T supports rail-to-rail analog signal handling from 0V to V+, with minimal RON variation across the full range. At +3V supply, RON flatness is guaranteed ≤1Ω, and the device maintains <2.5Ω max on-resistance even at VCOM = 0V or V+. This capability allows MAX4687EBT-T to pass full-scale audio, sensor, and power signals without clipping or gain error in precision front-end applications.
What is the maximum allowable supply voltage for the MAX4687EBT-T?
The absolute maximum supply voltage (V+) for the MAX4687EBT-T is +6V, but the recommended operating range is +1.8V to +5.5V. Exceeding +6V risks permanent damage due to internal diode breakdown. For reliable long-term operation, V+ should be kept within specification limits, especially when driving analog signals near V+-the internal clamping diodes activate at V+ + 0.3V, requiring external current limiting above that threshold. Always power V+ before applying analog signals to avoid latch-up.
Can the MAX4687EBT-T be driven directly by a 1.8V microcontroller GPIO?
Yes, the MAX4687EBT-T features 1.8V logic-compatible inputs: VIH is guaranteed ≥1.4V and VIL ≤0.5V over temperature, allowing direct connection to 1.8V GPIOs without level shifters. The IN pin tolerates voltages up to +5.5V regardless of V+, so it can also interface with 3.3V or 5V controllers. This flexibility simplifies system design and reduces BOM cost-especially valuable in compact portable devices where MAX4687EBT-T is commonly deployed for audio and sensor switching.
What package type does the MAX4687EBT-T use, and what are its PCB layout considerations?
The MAX4687EBT-T uses a 6-bump, 0.5mm pitch UCSP-6 (Ultra-Chip-Scale Package) measuring 1.50mm × 1.02mm. Layout requires strict adherence to JEDEC J-STD-020A reflow profiles (preheat mandatory; hand/wave soldering prohibited). Solder mask-defined pads, controlled thermal mass, and avoidance of mechanical stress on bumps are critical. The A2 bump (I.C.) must remain unconnected or grounded per Maxim's UCSP application note-incorrect handling compromises reliability. This package enables MAX4687EBT-T integration into ultra-thin wearables where traditional SO-8 or TSSOP packages are prohibitive.
