Product details
Overview
The MAX4523EUE+ from Maxim Integrated is a quad SPST analog switch IC with two normally open (NO) and two normally closed (NC) channels, designed for rail-to-rail signal routing in low-voltage systems. It features 100Ω max on-resistance at ±5V supplies, 4Ω max channel matching, 12Ω max on-resistance flatness, <1µW power consumption, and >2kV ESD protection - enabling precision signal switching in battery-powered test equipment and avionics interfaces.
For engineers reviewing the MAX4523EUE+ datasheet, MAX4523EUE+ pinout, MAX4523EUE+ application, or MAX4523EUE+ equivalent, key selection criteria include dual-supply (±2V to ±6V) or single-supply (+2V to +12V) operation, TTL/CMOS-compatible logic thresholds, break-before-make timing (5–20ns), and TSSOP-16 package compatibility with industry-standard DG211/DG212/DG213 footprints.
Technical Context
The MAX4523EUE+ implements four independent CMOS transmission gates using complementary N- and P-channel MOSFETs per switch, driven by level-translated logic inputs to support rail-to-rail analog signals from V− to V+. Its internal architecture includes reverse-biased ESD diodes between each analog pin and both V+ and V−, defining leakage paths and limiting analog voltage range.
Unlike the MAX4521 (4× NC) and MAX4522 (4× NO), the MAX4523EUE+ integrates mixed topology: switches 1 & 4 are NO, while switches 2 & 3 are NC - enabling simultaneous signal path enablement and default-path continuity in fault-tolerant routing applications without external pull-up/down components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V supplies - ensures minimal signal attenuation and voltage drop in precision analog paths. |
| On-resistance match (ΔRON) | 4Ω max between channels - enables matched gain/attenuation across multiplexed sensor or audio channels. |
| On-resistance flatness (RFLAT) | 12Ω max over full signal range - maintains consistent insertion loss across rail-to-rail input voltages. |
| Off-leakage current | 10nA max at +85°C - preserves high-impedance signal integrity in data acquisition front-ends. |
| Break-before-make delay (tBBM) | 5–20ns - prevents momentary shorting during channel switching in mixed-signal routing. |
| Logic threshold (VIN_H / VIN_L) | +1.6V to +2.4V / +0.8V to +1.6V - guarantees reliable TTL/CMOS compatibility with +5V digital control. |
| Supply range | ±2V to ±6V dual or +2V to +12V single - supports portable, industrial, and avionics power architectures. |
Pinout & Package
MAX4523EUE+ uses a 16-pin TSSOP package (U16-2, 4.4mm body width) with exposed pad connected to V+. Pin functions are validated per Maxim's official pin configuration diagram for MAX4523 (TSSOP/SO column).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-high logic drives respective switch state (NO/NC). |
| 2, 7, 10, 15 | COM1–COM4 | Common analog terminals; bidirectional signal path interface for all switches. |
| 3, 6 | NO1, NO4 | Normally open analog terminals; connect to COM only when IN = high. |
| 11, 14 | NC2, NC3 | Normally closed analog terminals; connect to COM when IN = low (default path). |
| 4 | V− | Negative supply rail; tied to GND for single-supply operation. |
| 5 | GND | Digital ground reference; no analog signal reference - analog signals float between V+ and V−. |
| 12 | V+ | Positive supply rail; powers analog switches and internal logic; internally connected to substrate. |
| 13 | N.C. | No internal connection; must be left unconnected. |
Key Features
| Feature | Design Value |
|---|---|
| Mixed NO/NC topology | Two NO (switches 1 & 4) and two NC (switches 2 & 3) channels enable fail-safe signal routing without external biasing. |
| Rail-to-rail analog handling | Supports signals from V− to V+ - eliminates level-shifting requirements in ±5V or +3.3V systems. |
| Low charge injection (1–5pC) | Minimizes voltage glitch on sampled-hold nodes and ADC inputs during switching transitions. |
| Pin compatibility with DG211/DG212/DG213 | Enables drop-in replacement in legacy designs without PCB layout changes. |
| ESD protection (>2kV per Method 3015.7) | Reduces need for external transient suppression in handheld and field-deployable test gear. |
Applications
| Battery-Operated Test Equipment | Avionics Signal Routing |
|---|---|
Use Scenario: Multiplexing sensor inputs and calibration references in portable multimeters and handheld oscilloscopes. IC Role / Device Role / Timing Role: Quad SPST switch routes analog signals between sensors, references, and ADC front-end under microcontroller control. Use Value: Low on-resistance (100Ω) and flatness (12Ω) preserve measurement accuracy; <1µW quiescent power extends battery life. |
Use Scenario: Selecting between redundant flight control signals or navigation data sources in cockpit display units. IC Role / Device Role / Timing Role: Mixed NO/NC configuration provides default signal path (NC) with override capability (NO) for fault recovery. Use Value: Break-before-make timing (5–20ns) prevents bus contention; -40°C to +85°C rating meets DO-160 environmental requirements. |
| Audio Signal Switching | Data Acquisition Front-End |
Use Scenario: Channel selection and input gain switching in professional audio mixers and studio interfaces. IC Role / Device Role / Timing Role: Bidirectional COM/NO/NC terminals route line-level or mic-level signals with minimal crosstalk (<-90dB). Use Value: Rail-to-rail operation handles ±2.5V audio swings; low off-capacitance (2pF) preserves high-frequency response up to 50MHz. |
Use Scenario: Multiplexing thermocouple, RTD, and strain gauge inputs into a shared precision ADC in industrial PLC modules. IC Role / Device Role / Timing Role: Low leakage (10nA @ +85°C) prevents offset drift in high-impedance sensor bridges. Use Value: Matched on-resistance (4Ω max) ensures consistent channel gain; 125Ω on-resistance at +3V supports low-power sensor excitation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4522EUE+ | Four NO-only switches; identical pinout, package, and electrical specs except NC functionality removed. | Suitable where all paths require active-enable behavior; lacks default-closed redundancy of MAX4523EUE+. | Select MAX4522EUE+ when system design requires uniform NO topology and no fail-safe path needed. |
| ADG1412BRUZ | Quad SPST, 1.5Ω typical RON, ±15V max supply, but no NC/NO mixing; LFCSP-16 package (not pin-compatible). | Higher performance for precision instrumentation; incompatible footprint requires PCB redesign. | Choose ADG1412BRUZ only when ultra-low on-resistance and wider supply range outweigh layout cost. |
Compared with MAX4522EUE+, the MAX4523EUE+ adds NC functionality for default-path reliability, while ADG1412BRUZ offers lower RON but demands mechanical redesign - making MAX4523EUE+ optimal for mixed-path routing in space-constrained TSSOP layouts.

FAQ
What is the operating temperature range for MAX4523EUE+?
The MAX4523EUE+ is rated for -40°C to +85°C operation, as confirmed by Maxim's Ordering Information table (MAX4523EUE part number suffix "E" denotes extended temperature grade). This range supports deployment in industrial control panels, outdoor test gear, and avionics subsystems without derating.
Does MAX4523EUE+ support single-supply operation?
Yes, MAX4523EUE+ operates from a single +2V to +12V supply when V− is connected to GND. Electrical characteristics are fully specified down to +2.7V, with 250Ω max on-resistance at +4.5V and 600Ω at +2.7V - enabling use in 3.3V and 5V embedded systems.
How does the mixed NO/NC configuration of MAX4523EUE+ benefit system design?
The MAX4523EUE+ integrates two NO (IN1/IN4) and two NC (IN2/IN3) switches, allowing one pair to provide active-enable paths while the other maintains default connectivity. This eliminates external pull resistors in fail-safe sensor monitoring or redundant signal selection circuits.
Is MAX4523EUE+ pin-compatible with DG211/DG212/DG213?
Yes, MAX4523EUE+ is explicitly stated as pin-compatible with DG211/DG212/DG213 in its Features list. The TSSOP-16 pinout matches function-for-function, enabling direct replacement in legacy designs without layout modification or firmware changes.
What is the maximum allowable V+ to V− differential voltage for MAX4523EUE+?
The absolute maximum V+ to V− differential is 13.0V, as specified in Absolute Maximum Ratings. At ±6V nominal supplies (12V total), 10% tolerance yields 13.2V - exceeding the limit. Designers must verify worst-case supply tolerances or use clamping to avoid permanent damage to MAX4523EUE+.
