Product details
Overview
MAX14756EUE+ from Maxim Integrated is a quad normally closed (NC) single-pole/single-throw (SPST) analog switch with 10Ω max on-resistance, rail-to-rail ±35V dual-supply or +10V to +70V single-supply operation, and -40°C to +85°C temperature range. It routes high-voltage analog signals in industrial control systems and battery management circuits where fail-safe closed-path behavior is required.
For engineers reviewing the MAX14756EUE+ datasheet, MAX14756EUE+ pinout, MAX14756EUE+ application, or MAX14756EUE+ equivalent, key selection criteria include NC default state, 0.004Ω on-resistance flatness, ±50mA continuous switch current, 2.5nA max off-leakage at +85°C, and TSSOP-16 package compatibility with high-voltage signal routing layouts.
Technical Context
The MAX14756EUE+ uses BiCMOS process technology to achieve low on-resistance (5Ω typ / 10Ω max) and ultra-flat RON variation (0.004Ω typ) across its full ±35V bipolar or +70V unipolar analog signal range. Its four independent SPST switches are controlled by logic-level enable inputs referenced to VL (1.6V–11V), with internal protection diodes enabling overvoltage/undervoltage clamping.
Each channel operates bidirectionally with matched on-resistance (≤0.5Ω mismatch) and exhibits 65dB off-isolation at 100kHz, 96dB crosstalk suppression, and 145MHz -3dB bandwidth-enabling precision audio and ATE signal routing without distortion or coupling artifacts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 10Ω max ensures minimal voltage drop and power loss when switching ±50mA analog signals up to ±35V. |
| On-Resistance Flatness | 0.004Ω typ guarantees consistent gain and linearity across the full analog input range, critical for precision instrumentation. |
| Off-Leakage Current | 2.5nA max at +85°C prevents signal corruption in high-impedance sensor interfaces and battery monitoring paths. |
| Supply Range | +10V to +70V (unipolar) or ±35V (bipolar) supports industrial HV rails without external level-shifting circuitry. |
| Switch Bandwidth | 145MHz -3dB bandwidth enables clean routing of audio, test tones, and fast control signals without attenuation. |
| Charge Injection | 580pC limits DC offset errors in sample-and-hold and multiplexer applications requiring low settling error. |
| Logic Supply (VL) | 1.6V–11V compatible with 1.8V, 3.3V, and 5V microcontrollers-no separate level translators needed. |
Pinout & Package
MAX14756EUE+ is housed in a 16-pin TSSOP package (JEDEC MO-153, 5mm × 4.4mm, 0.65mm pitch) with exposed pad for thermal enhancement. Pin 1 is A1 (Terminal A of Switch 1); pin 5 is GND; pin 12 is VL (logic supply); pins 13 and 4 are VDD and VSS (power supplies); pins 3, 6, 11, and 14 are EN1–EN4 (independent enable inputs).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 8, 9, 10, 15, 16 | A1/B1–A4/B4 analog terminals | Four bidirectional NC SPST switch pairs; A-side and B-side interchangeable; support ±50mA continuous current. |
| 3, 6, 11, 14 | EN1–EN4 enable inputs | Active-high logic controls; drive high to open switch (NC default), low to close; compatible with 1.6V–11V VL. |
| 4, 13 | VSS, VDD | Negative and positive analog supplies; support asymmetric bipolar rails (e.g., VSS = -10V, VDD = +60V). |
| 5 | GND | Digital ground reference for VL and enable logic; must be tied to system ground with low-inductance path. |
| 12 | VL | Separate logic supply input; decoupled with 1µF ceramic capacitor; sets VIH/VIL thresholds (0.75×/0.25× VL). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal range | Supports input signals from VSS to VDD without clipping-enables direct interfacing with ±35V sensors or +70V battery stacks. |
| Overvoltage/undervoltage clamping | Internal protection diodes limit A/B terminal voltages beyond VDD/VSS rails, eliminating need for external TVS or clamp diodes. |
| Functionally compatible to DG411/DG412/DG413 | Enables drop-in replacement in legacy designs using industry-standard quad SPST switch footprints and logic behavior. |
| 0.004Ω on-resistance flatness | Maintains constant gain and THD+N < 0.001% across full signal swing-critical for medical-grade audio and precision data acquisition. |
| Operational up to +125°C | Validated functionality at elevated temperature with increased leakage only; suitable for under-hood or enclosed industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX14757EUE+ | Quad NO (normally open) SPST vs. MAX14756EUE+'s quad NC; identical pinout, specs, and package. | Suitable where default-open safety state is required (e.g., disabling power paths on startup). | Select MAX14757EUE+ when fail-safe open behavior is mandated; otherwise, MAX14756EUE+ provides default-closed continuity. |
| ADG1419BRUZ | Quad SPST, ±15V max supply, 1.5Ω max RON, 16-TSSOP but different pin mapping and no VL supply. | Limited to lower-voltage industrial and lab equipment; lacks overvoltage clamping and extended temperature rating. | Choose ADG1419BRUZ only for cost-sensitive, low-voltage (<±20V) applications where 1.5Ω RON outweighs HV capability. |
Compared with MAX14757EUE+, MAX14756EUE+ provides inherent power-loss continuity; compared with ADG1419BRUZ, it delivers 2.3× higher voltage range, integrated clamping, and guaranteed +125°C operation-making it uniquely suited for harsh-environment HV analog routing.

FAQ
What is the default switch state of MAX14756EUE+?
The MAX14756EUE+ is a quad normally closed (NC) SPST switch: all four channels conduct (A1↔B1, A2↔B2, A3↔B3, A4↔B4) when EN1–EN4 are logic low (0V). Driving any EN pin high opens that specific switch. This NC default ensures signal continuity during power-up or controller initialization-critical for safety-critical industrial and medical systems where loss of signal path could cause hazardous conditions. The MAX14756EUE+ truth table confirms closed state at EN = 0.
Can MAX14756EUE+ operate with asymmetric bipolar supplies?
Yes, MAX14756EUE+ supports asymmetric bipolar supplies: VDD and VSS need not be symmetrical (e.g., VDD = +60V, VSS = -10V is valid), and the analog signal range remains rail-to-rail from VSS to VDD. This flexibility allows integration into nonstandard HV rails common in battery test equipment and programmable power supplies. The absolute maximum ratings specify VDD to VSS ≤ +72V and VSS to GND ≥ -36V, permitting wide offset configurations without performance degradation. The MAX14756EUE+ datasheet explicitly states "bipolar supplies can be offset and do not have to be symmetrical."
What is the maximum continuous current per switch in MAX14756EUE+?
The MAX14756EUE+ supports ±50mA continuous current through each A/B terminal pair under normal operation. Exceeding this limit causes internal leakage current to flow from the switch to VSS, but does not damage the device if absolute maximum ratings (e.g., ±100mA peak, 889mW power dissipation at +70°C) are respected. This ±50mA rating is validated across the full -40°C to +85°C operating range and enables robust signal routing in motor control feedback loops and high-current sensor interfaces. The MAX14756EUE+ Electrical Characteristics table lists "Current Through Switch" as ±50mA.
Does MAX14756EUE+ require external protection diodes for overvoltage events?
No, MAX14756EUE+ integrates overvoltage/undervoltage clamping diodes from each A/B terminal to VDD and VSS, eliminating the need for external protection components. During overvoltage (e.g., A1 > VDD + 0.3V) or undervoltage (A1 < VSS – 0.3V), these diodes conduct, limiting terminal voltage to safe levels. External series resistors (RLIM) are recommended to restrict fault current to ≤100mA, calculated using RLIM+ = (VIN(MAX) – VDD)/100mA and RLIM– = (VSS – VIN(MIN))/100mA. This integrated clamping is confirmed in the MAX14756EUE+ Features list and Figure 9.
Is MAX14756EUE+ pin-compatible with industry-standard quad SPST switches?
Yes, MAX14756EUE+ is functionally compatible with DG411, DG412, and DG413-legacy quad SPST switches widely used in industrial designs. While pin assignments differ slightly (e.g., DG411 uses different enable logic polarity), the MAX14756EUE+ TSSOP-16 footprint matches standard layouts, and its NC configuration directly replaces DG411 in fail-safe applications. The MAX14756EUE+ datasheet explicitly states "functionally compatible to DG411, DG412, and DG413," and its 16-TSSOP package (U16+1) aligns with JEDEC MO-153 land patterns used for these predecessors.
