Product details
Overview
MAX14752EUE+ from Maxim Integrated is an 8-channel (8-to-1) high-voltage analog multiplexer IC designed for precision signal routing in industrial and test equipment. It delivers 60Ω typical on-resistance, 0.03Ω typical on-resistance flatness, and operates from ±10V to ±36V dual supplies or +20V to +72V single supply - enabling rail-to-rail analog switching in programmable logic controllers and ATE systems.
For engineers reviewing the MAX14752EUE+ datasheet, MAX14752EUE+ pinout, MAX14752EUE+ application, or MAX14752EUE+ equivalent, key selection criteria include its 72V absolute max rating, low 20nA (max) on-leakage, 25µA disable-mode supply current, and pin compatibility with industry-standard DG408 - critical for legacy system upgrades and high-voltage signal integrity.
Technical Context
The MAX14752EUE+ implements a CMOS-based 8-to-1 analog switch architecture with bidirectional conduction and no power-supply sequencing requirement. Its EN input defines flexible logic thresholds (VEN_IL = 0.8V, VEN_IH = 2.1V), allowing interface with 1.8V–11V control signals while maintaining full analog range operation across ±36V or +72V supplies.
It features break-before-make switching (10µs tBBM), 20MHz bandwidth, 65dB off-isolation at 100kHz, and 200pC charge injection - ensuring minimal signal disturbance during channel transitions in medical monitoring and environment control systems where accuracy and transient immunity are essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±10V to ±36V dual or +20V to +72V single - supports wide industrial voltage rails without external level-shifting. |
| On-Resistance (RON) | 60Ω (typ), ≤130Ω (max) - ensures minimal signal attenuation and gain error in precision measurement paths. |
| RON Flatness | 0.03Ω (typ) over common-mode range - preserves linearity and THD+N (0.0014%) across full input swing. |
| On-Leakage Current | ±20nA (max) at ±20V - reduces offset drift and measurement uncertainty in high-impedance sensor interfaces. |
| Enable Switching Time | tON = 1µs (typ), tOFF = 0.8µs (typ) - enables fast channel reconfiguration in automated test equipment. |
| Off-Isolation | 65dB at 100kHz - suppresses crosstalk between unselected channels in multi-signal acquisition systems. |
| Charge Injection | 200pC - limits voltage glitch on high-impedance loads (e.g., sample-and-hold capacitors) during switching. |
Pinout & Package
MAX14752EUE+ is housed in a 16-pin TSSOP package (JEDEC MO-153, 4.4mm × 5.0mm), RoHS-compliant, with exposed pad not electrically connected. Thermal resistance θJA = 90°C/W enables operation up to +85°C ambient without forced airflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15, 16 | S0, S2, S1 | Binary channel select inputs (S2 MSB); logic levels referenced to EN voltage - enables direct microcontroller interface without level shifters. |
| 2 | EN | Enable input; high = active; sets logic threshold for S0–S2 - allows dynamic control of logic compatibility (1.8V–11V). |
| 3, 13 | VSS, VDD | Negative/positive supply pins; support asymmetric operation (e.g., +36V/−10V) - simplifies mixed-voltage system design. |
| 4–7, 9–12 | IN0–IN7 | Bidirectional analog inputs; rated for ±2V to (VDD−VSS+2V) - accommodates beyond-the-rail signals within absolute max ratings. |
| 8 | OUT | Bidirectional analog output; shares same voltage and current specs as inputs - enables flexible signal path routing. |
| 14 | GND | Ground reference; tied to VSS in single-supply mode - eliminates need for separate ground plane in +72V systems. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog range | Supports VIN/VOUT from VSS to VDD - eliminates external clamping diodes in ±36V PLC I/O modules. |
| Asymmetric supply operation | Accepts unbalanced dual supplies (e.g., +36V/−10V) - reduces power supply complexity in multi-range instrumentation. |
| Low disable-mode IDD | 25µA max - extends battery life in portable medical monitors using intermittent sampling. |
| DG408/DG409 pin compatibility | Direct drop-in replacement with identical pinout and footprint - accelerates upgrade of legacy ATE hardware without PCB redesign. |
| Break-before-make switching | 10µs guaranteed interval - prevents momentary short-circuits during channel transitions in safety-critical control systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX14753EUE+ | Dual 4-to-1 configuration (vs. single 8-to-1); identical RON (60Ω), leakage (20nA), and supply range - shares same 16-TSSOP package and pinout except channel mapping. | Preferred when independent switching of two 4-channel groups is required (e.g., dual ADC inputs), not for single-path 8:1 routing. | Select MAX14753EUE+ only if system architecture requires isolated 4-channel banks; otherwise MAX14752EUE+ provides simpler control and lower component count. |
| DG408DJ | Higher RON (100Ω typ), wider RON flatness (1.5Ω), lower supply max (±20V), no asymmetric supply support - legacy part with larger package (16-SOIC). | Suitable for lower-voltage (<±20V), cost-sensitive designs where 0.03Ω flatness and 72V capability are unnecessary. | Choose DG408DJ only for retrofitting older designs with identical SOIC footprint; MAX14752EUE+ offers superior performance and modern TSSOP packaging. |
Compared with MAX14753EUE+, the MAX14752EUE+ provides unified 8-channel selection with single enable and address bus - reducing MCU GPIO usage and PCB routing complexity. Against DG408DJ, it delivers 40% lower on-resistance, 50× better flatness, and 3.6× higher voltage capability - enabling next-generation high-accuracy, high-voltage data acquisition.

FAQ
What supply voltage ranges does the MAX14752EUE+ support?
The MAX14752EUE+ operates from ±10V to ±36V dual supplies or +20V to +72V single supply, including asymmetric configurations like +36V/−10V. This flexibility eliminates external level-shifting in mixed-voltage industrial systems and ensures compatibility with legacy ±15V and modern +48V/−24V rails. The MAX14752EUE+ maintains full specified performance across this entire range.
Is the MAX14752EUE+ pin-compatible with the DG408?
Yes, the MAX14752EUE+ is pin-compatible with the industry-standard DG408 in the 16-pin TSSOP package. Pin functions (S0–S2, EN, IN0–IN7, OUT, VDD, VSS, GND) match exactly, and electrical characteristics exceed DG408 specifications - including lower on-resistance (60Ω vs. 100Ω), tighter flatness (0.03Ω vs. 1.5Ω), and higher voltage rating (+72V vs. ±20V). The MAX14752EUE+ enables seamless drop-in upgrades.
What is the maximum allowable current through the MAX14752EUE+ channels?
The MAX14752EUE+ specifies ±5mA maximum continuous current per on-channel under normal operation. Exceeding this limit induces internal leakage to VSS but does not damage the device if total power dissipation remains below 890mW. For robust design, current-limiting resistors should be used in series with inputs/outputs when fault currents could exceed ±5mA - especially in ATE and PLC applications with variable DUT impedance.
How does the EN pin affect logic-level compatibility of the MAX14752EUE+?
The EN pin on the MAX14752EUE+ defines the logic threshold for S0, S1, and S2 inputs: VIH = 0.75 × VEN and VIL = 0.25 × VEN. With VEN set to 3.3V, S0–S2 accept standard 3.3V logic; with VEN = 5V, they interface directly with 5V microcontrollers. This eliminates external level shifters and supports mixed-voltage control domains - a key advantage of the MAX14752EUE+ in heterogeneous embedded systems.
Does the MAX14752EUE+ require power-supply sequencing?
No, the MAX14752EUE+ does not require power-supply sequencing. Its CMOS architecture allows VDD and VSS to be powered in any order, and the device remains functional during supply ramp-up or brownout conditions. This simplifies power management in systems with multiple rails (e.g., +24V analog, +3.3V digital) and improves reliability in industrial environments subject to voltage transients - a confirmed behavior documented in the MAX14752EUE+ datasheet.
