Product details
Overview
MAX14758EUE+ from Maxim Integrated is a dual normally open (NO) and dual normally closed (NC) SPST analog switch IC with rail-to-rail signal handling, 10Ω max on-resistance, ±35V bipolar or +70V unipolar supply operation, and operation over –40°C to +85°C - used in high-voltage industrial signal routing where bidirectional conduction and low leakage are critical.
For engineers reviewing the MAX14758EUE+ datasheet, MAX14758EUE+ pinout, MAX14758EUE+ application, or MAX14758EUE+ equivalent, key selection criteria include verified 5Ω typical on-resistance, 0.004Ω on-resistance flatness, 2.5nA max off-leakage at +85°C, and TSSOP-16 package compatibility with high-voltage analog switching requirements in battery management and ATE systems.
Technical Context
The MAX14758EUE+ integrates four independent SPST switches in one TSSOP-16 package, with two configured as NO and two as NC - enabling flexible signal path control without external logic inversion. Its BiCMOS process supports rail-to-rail analog input range (VSS to VDD), ±100mA continuous channel current, and internal protection diodes for overvoltage/undervoltage clamping.
Switch control uses four independent enable inputs (EN1–EN4) referenced to VL (1.6V to 11V logic supply), with defined truth table behavior: EN = 0 holds Switch 1 & 4 in NC state and Switches 2 & 3 in NO state, while EN = 1 toggles each pair. Dynamic performance includes 35µs typical turn-on time and 96dB crosstalk suppression at 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (max) | 10Ω - ensures minimal voltage drop and power loss across switched analog signals up to ±50mA. |
| On-resistance flatness (typ) | 0.004Ω - maintains consistent gain and linearity across full analog-signal range (VSS to VDD). |
| Off-leakage current (max) | 2.5nA at +85°C - preserves signal integrity in high-impedance sensor or precision instrumentation paths. |
| Supply range | +10V to +70V (unipolar) or ±35V (bipolar) - supports industrial HV signal chains without external level shifting. |
| Bandwidth (-3dB) | 145MHz - enables audio and medium-frequency analog multiplexing without significant attenuation. |
| Charge injection (typ) | 580pC - limits transient glitches during switching in sample-and-hold or data acquisition circuits. |
| THD+N (20Hz–20kHz) | 0.001% - meets low-distortion audio routing requirements without added filtering. |
Pinout & Package
MAX14758EUE+ is housed in a RoHS-compliant 16-pin TSSOP package (4.4mm × 5mm, 0.65mm pitch), thermally rated for 889mW at +70°C ambient with θJA = 90°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 (A1–A4) | Analog terminal A per switch | High-voltage analog input/output node; supports rail-to-rail voltage swing (VSS to VDD). |
| 2, 7, 10, 15 (B1–B4) | Analog terminal B per switch | Second high-voltage analog node; bidirectional conduction identical to A-side. |
| 3, 6, 11, 14 (EN1–EN4) | Digital enable input per switch | Active-high logic control (0.25×VL / 0.75×VL thresholds); drives internal NMOS/PMOS gate stack. |
| 4 (VSS) | Negative supply rail | Bipolar negative rail or ground reference in unipolar mode; requires 1µF ceramic bypass. |
| 5 (GND) | Logic ground reference | Separate from VSS to isolate digital noise; connects to system ground plane. |
| 12 (VL) | Logic supply voltage | Independent 1.6V–11V supply for enable inputs; decoupled with 1µF ceramic capacitor. |
| 13 (VDD) | Positive supply rail | Unipolar +10V–+70V or bipolar +35V rail; requires 1µF 100V-rated ceramic bypass. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal range | Supports full VSS-to-VDD swing without clipping - essential for ±10V instrumentation and HV sensor interfaces. |
| Functionally compatible with DG411/DG412/DG413 | Enables drop-in replacement in legacy designs using industry-standard quad SPST switch footprints and logic. |
| Overvoltage/undervoltage clamping | Internal protection diodes limit A/B pins to VDD + 0.3V and VSS − 0.3V - eliminates need for external TVS in many field applications. |
| Low THD+N (0.001%) | Preserves audio fidelity in routing paths without post-switch equalization or buffering. |
| Operational up to +125°C | Enables use in under-hood automotive subsystems or industrial enclosures with elevated ambient temperatures. |

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-only configuration; identical RON, leakage, and supply specs but no NC functionality. | Suitable only where all four channels require normally open behavior - not usable when NC paths are needed for fail-safe routing. | Select MAX14757EUE+ only if design requires uniform NO behavior and simplifies enable logic. |
| ADG1414BRUZ | Quad SPST, ±15V max supply, 1.8Ω RON, 16-TSSOP, but lacks bipolar ±35V capability and rail-to-rail beyond supplies. | Better for low-voltage, low-RON audio or data acquisition; unsuitable for >±20V industrial signal conditioning. | Choose ADG1414BRUZ when supply headroom is limited and ultra-low on-resistance outweighs HV range. |
Compared with MAX14757EUE+, the MAX14758EUE+ provides mixed NO/NC topology for redundant or safety-critical path control, while ADG1414BRUZ trades HV capability for lower RON and faster switching - making MAX14758EUE+ uniquely suited for industrial HV multiplexing where both voltage range and configurable default states are mandatory.

FAQ
What is the maximum allowable analog signal voltage range for MAX14758EUE+?
The MAX14758EUE+ supports a rail-to-rail analog signal range from VSS to VDD. With ±35V dual supplies, this means ±35V across terminals A and B; with +70V single supply and VSS = GND, it supports 0V to +70V. Absolute maximum ratings allow A/B pins to swing to VDD + 2V or VSS − 0.3V, but sustained operation must stay within VSS to VDD for specified performance.
Can MAX14758EUE+ operate with asymmetric bipolar supplies?
Yes, the MAX14758EUE+ explicitly supports asymmetric bipolar supplies - for example, VDD = +25V and VSS = −10V is valid. The device does not require symmetrical rails, and its internal architecture maintains proper biasing and switching behavior across any combination within the absolute maximum ratings (VDD − VSS ≤ +72V, VSS ≥ −36V).
How does the dual NO/dual NC configuration of MAX14758EUE+ differ from MAX14756EUE+ and MAX14757EUE+?
The MAX14758EUE+ integrates two NO and two NC SPST switches in one package, whereas MAX14756EUE+ is quad NC and MAX14757EUE+ is quad NO. This mixed configuration enables fail-safe designs - e.g., NC paths maintain default connectivity during power loss, while NO paths isolate during fault conditions - without requiring external logic or additional ICs.
What is the thermal derating behavior of MAX14758EUE+ above +70°C ambient?
The MAX14758EUE+ has a thermal resistance θJA of 90°C/W and a maximum junction temperature of +150°C. At +70°C ambient, its continuous power dissipation is rated at 889mW; above that, it derates linearly at 11.1mW/°C. For example, at +85°C ambient, max dissipation drops to ~722mW - requiring careful layout and copper pour to maintain safe junction temperature.
Does MAX14758EUE+ require external protection diodes for overvoltage events?
No - the MAX14758EUE+ includes internal protection diodes from each A/B terminal to VDD and VSS. When input voltage exceeds VDD + 0.3V or falls below VSS − 0.3V, these diodes clamp the signal. External series resistors (calculated per datasheet equations) are required to limit clamp current to ≤100mA, but no discrete diodes are needed for basic overvoltage/undervoltage protection.
