Product details
Overview
MAX4523CSE from Maxim Integrated is a quad SPST analog switch 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 (±5V supplies), 4Ω max channel matching, 12Ω max on-resistance flatness, <1µW power consumption, and operates from +2V to +12V single supply or ±2V to ±6V dual supplies. It is used in audio signal routing, data acquisition, and battery-operated test equipment.
For engineers reviewing the MAX4523CSE datasheet, MAX4523CSE pinout, MAX4523CSE application, or MAX4523CSE equivalent, key selection criteria include its mixed NO/NC configuration, break-before-make timing (5–20 ns), TTL/CMOS-compatible logic thresholds (+0.8V/2.4V), >2kV ESD protection, and pin compatibility with DG211/DG212/DG213 for drop-in replacement in legacy designs.
Technical Context
The MAX4523CSE implements four independent CMOS SPST switches using complementary N- and P-channel MOSFETs per channel, enabling bidirectional rail-to-rail analog signal handling. Its logic-level translators isolate digital control (IN1–IN4) from analog supplies (V+, V−), supporting TTL/CMOS inputs at ±5V or +5V while driving internal gates with switched V+ and V− signals.
Unlike MAX4521 (all-NC) and MAX4522 (all-NO), the MAX4523CSE integrates two NO (pins 1, 16) and two NC (pins 14, 11) switches in one 16-pin narrow SO package. Its break-before-make timing (tBBM = 5–20 ns at +25°C) prevents momentary shorting during channel switching - a critical feature for multiplexer and signal-gating applications requiring glitch-free transitions.
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 accurate gain/offset matching in multi-channel instrumentation. |
| On-resistance flatness (RFLAT) | 12Ω max over signal range - maintains consistent channel impedance across full rail-to-rail input swing. |
| Off-leakage current | 1nA at +25°C, 10nA at +85°C - preserves signal integrity in high-impedance sensor or sample-hold circuits. |
| Supply range | +2V to +12V single or ±2V to ±6V dual - supports portable (3.3V/5V) and industrial (±5V) signal chain architectures. |
| Logic thresholds | +0.8V low / +2.4V high - guarantees reliable TTL/CMOS interfacing without level-shifting circuitry. |
| Break-before-make delay | 5–20 ns (MAX4523 only) - eliminates transient shorts when switching between signal sources. |
Pinout & Package
MAX4523CSE is housed in a 16-pin narrow SOIC (S16-2) package with 1.27 mm pitch, 3.9 mm width, and exposed pad (not present in SO variant). Pin 1 is IN1; pins 2 and 5 are V− and GND respectively; pins 11 and 13 are V+ and N.C.; pins 1, 16, 14, 11 route NO1, NO4, NC2, NC3; COM terminals occupy pins 13, 15, 7, 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3, IN4 (pins 15, 14, 7, 6) | Digital control input | Active-high logic drives corresponding switch; compatible with 0.8V/2.4V TTL/CMOS thresholds. |
| COM1–COM4 (pins 13, 15, 7, 6 → re-assigned) | Analog common terminal | Bidirectional signal path node; connects to load or source depending on NO/NC configuration. |
| NO1, NO4 (pins 1, 16) | Normally open analog terminal | Connects to COMx only when INx = high; used for gated signal insertion or enable paths. |
| NC2, NC3 (pins 14, 11) | Normally closed analog terminal | Connects to COMx when INx = low; provides default signal path with active-low interruption. |
| V+ (pin 13), V− (pin 2) | Analog supply rails | Set analog signal range limits (V− to V+); internally connect to substrate and ESD diodes. |
| GND (pin 5) | Digital ground reference | Reference for logic inputs only; no connection to analog signal paths - enables true floating operation. |
Key Features
| Feature | Design Value |
|---|---|
| Mixed NO/NC configuration | Two NO and two NC switches enable flexible signal routing topologies - e.g., default-path + override-path in safety-critical I/O modules. |
| Rail-to-rail analog operation | Supports input signals from V− to V+ without clipping - essential for ±5V op-amp interfaces and unipolar/bipolar ADC front-ends. |
| Break-before-make timing | Guaranteed 5–20 ns tBBM prevents momentary short-circuits during channel switching - required for fault-tolerant multiplexers. |
| Low charge injection (1–5 pC) | Minimizes voltage glitches in sample-and-hold or DAC output buffering - critical for 12-bit+ data acquisition accuracy. |
| Pin compatibility with DG211/DG212/DG213 | Enables direct PCB replacement in legacy designs without layout changes - reduces redesign cost and qualification time. |
| ESD protection >2kV (HBM) | Withstands electrostatic discharge per Method 3015.7 - improves robustness in benchtop test equipment and field-deployable instruments. |
Applications
| Audio Signal Routing | Data Acquisition Systems |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4522CSE | All four channels are normally open (NO); no NC functionality; otherwise identical pinout, specs, and package. | Suitable where all signal paths require active-enable behavior - e.g., programmable gain amplifier switching. | Select MAX4522CSE when default-open topology is required; MAX4523CSE preferred for fail-safe default-closed paths. |
| ADG1412BRUZ | Quad SPST, 1.5Ω typical RON, ±15V supply capable, but requires external level shifters for TTL logic and lacks break-before-make timing. | Better for high-precision, high-voltage industrial DAQ; not drop-in due to different logic interface and timing behavior. | Choose ADG1412BRUZ only when sub-2Ω RON and ±15V operation outweigh need for integrated logic compatibility and tBBM. |
Compared with MAX4522CSE (all-NO) and ADG1412BRUZ (low-RON, high-voltage), the MAX4523CSE uniquely delivers mixed NO/NC functionality with guaranteed break-before-make timing and native TTL/CMOS logic support - making it optimal for safety-aware, low-power, and legacy-compatible signal routing.

FAQ
What is the operating temperature range for MAX4523CSE?
The MAX4523CSE is specified for 0°C to +70°C ambient operation (Commercial grade). This range is confirmed in the Ordering Information table and Absolute Maximum Ratings section. Extended temperature variants (e.g., MAX4523ESE) support −40°C to +85°C, but the 'C' suffix in MAX4523CSE explicitly denotes the 0°C to +70°C grade. All electrical characteristics in the datasheet's "C, E, M" columns apply to this temperature range.
Does MAX4523CSE support single-supply operation?
Yes, MAX4523CSE supports single-supply operation from +2V to +12V, with V− connected to GND. Electrical characteristics are fully specified down to +2.7V (e.g., 600Ω RON at +2.7V), and logic thresholds remain valid. The device retains rail-to-rail analog signal handling (0V to V+) and <1µW quiescent power in this mode - making it ideal for 3.3V and 5V battery-powered systems.
What is the function of pins 14 and 11 on MAX4523CSE?
On MAX4523CSE, pin 14 is NC2 (normally closed terminal for switch 2) and pin 11 is NC3 (normally closed terminal for switch 3). These are analog signal terminals that connect to COM2 and COM3 respectively when the corresponding IN2 or IN3 input is logic low. Their function is confirmed in the Pin Description table and MAX4523-specific pin diagram on page 12 of the datasheet.
Is MAX4523CSE pin-compatible with DG212?
Yes, MAX4523CSE is explicitly stated as pin-compatible with DG211/DG212/DG213 in the Features list and Pin Configurations section. All 16 pins map identically: IN1–IN4, COM1–COM4, V+, V−, GND, and N.C. positions align. This allows direct PCB replacement without layout modification - verified by side-by-side comparison of MAX4523 and DG212 pinouts in the datasheet.
What is the maximum allowable V+ to V− differential voltage for MAX4523CSE?
The absolute maximum V+ to V− differential voltage for MAX4523CSE is 13.0V, as stated in the Absolute Maximum Ratings table. Exceeding this - even momentarily due to supply overshoot or noise - risks permanent damage. For example, ±6V supplies (12V total) with ±10% tolerance reach 13.2V and must be avoided; ±5V (10V) is safe, and derating to ±4.5V (9V) adds margin for transients.
