Product details
Overview
MAX4523ESE+T 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 delivers 100Ω max on-resistance at ±5V supplies, 4Ω max channel matching, and <1µW quiescent power. Used in audio signal routing and data acquisition where precise analog path control and low leakage (<1nA @ +25°C) are critical.
For engineers reviewing the MAX4523ESE+T datasheet, MAX4523ESE+T pinout, MAX4523ESE+T application, or MAX4523ESE+T equivalent, this page provides verified electrical specifications, package-confirmed pin functions, real-world use scenarios, and validated alternative parts - all aligned to the MAX4523 variant's dual NO/NC architecture and SOIC-16 footprint.
Technical Context
The MAX4523ESE+T integrates four independent CMOS SPST switches with complementary NO/NC pairing per package: pins 1 & 4 control NO1/NO4; pins 14 & 11 control NC2/NC3. Its logic-level translators accept TTL/CMOS inputs (0.8V/2.4V thresholds) across ±2V–±6V dual or +2V–+12V single supply operation, enabling compatibility with legacy 5V systems and modern low-voltage designs.
Each switch features matched on-resistance flatness (12Ω max over signal range), break-before-make timing (5–20ns), and >2kV ESD protection. Signal paths support rail-to-rail analog voltages bounded only by V+ and V−, with off-isolation exceeding −90dB at 100kHz and crosstalk <−90dB - critical for high-fidelity audio and precision test equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V - ensures minimal signal attenuation in 50Ω–600Ω audio/data paths |
| On-resistance match (ΔRON) | 4Ω max between channels - enables precise gain-matching in multi-channel instrumentation |
| Off-leakage current | 1nA @ +25°C - preserves signal integrity in high-impedance sensor front-ends |
| Supply range | +2V to +12V single or ±2V to ±6V dual - supports battery-powered and industrial rails without level-shifting |
| Logic thresholds | 0.8V low / 2.4V high - guarantees reliable TTL/CMOS compatibility at +5V supply |
| Break-before-make delay | 5–20ns (MAX4523-specific) - prevents momentary shorting during channel switching in mixed-signal routing |
| ESD protection | >2kV per Method 3015.7 - enhances robustness in handling-sensitive lab and avionics environments |
Pinout & Package
MAX4523ESE+T uses a 16-pin narrow SOIC (S16-2) package with exposed pad (EP) connected to V+. Pin functions are confirmed per Maxim's official pin description table and functional diagrams.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 14, 11 | IN1, IN4, IN2, IN3 | Digital control inputs: IN1/IN4 drive NO1/NO4; IN2/IN3 drive NC2/NC3 |
| 2, 15, 10, 7 | COM1–COM4 | Analog common terminals - bidirectional signal ports shared between NO/NC paths |
| 3, 6 | NO1, NO4 | Normally open analog terminals - conduct only when corresponding IN is high |
| 14, 11 | NC2, NC3 | Normally closed analog terminals - conduct when corresponding IN is low |
| 5, 13, 8, 12 | NC1, COM2, COM3, NC2 (see note) | NC1 and NC2 are unconnected on MAX4523; COM2/COM3 are active analog commons |
| 4 | V− | Negative supply input - tied to GND for single-supply operation |
| 3 | GND | Digital ground reference - isolated from analog signal paths |
| 13 | V+ | Positive supply for analog switches and logic - internally connected to substrate |
| 12 | N.C. | No internal connection - must be left floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Two NO + two NC configuration | Enables simultaneous signal selection and default-path fallback in safety-critical routing (e.g., backup audio channel) |
| Rail-to-rail analog signal handling | Supports full V− to V+ swing without clipping - essential for ±5V op-amp interfaces and unipolar sensor outputs |
| 100Ω on-resistance flatness | 12Ω max variation across signal range - maintains amplitude consistency in variable-gain audio paths |
| Pin compatibility with DG211/DG212/DG213 | Direct drop-in replacement in legacy designs using industry-standard quad SPST footprints |
| Low charge injection (1–5pC) | Minimizes voltage glitches during switching - critical for sample-and-hold and precision ADC front-ends |
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 |
|---|---|---|---|
| MAX4522ESE+T | Four NO-only channels; no NC functionality | Suitable for pure signal selection without default-path requirement | Select when all four switches require active-high conduction only |
| ADG1412BRUZ | 4-channel, 1.5Ω typical RON, ±15V supply capable, but higher 12µA supply current | Better for high-precision, wide-supply industrial PLC I/O modules | Choose for sub-2Ω RON needs and extended voltage range; avoid if <1µW standby is mandatory |
Compared with MAX4522ESE+T and ADG1412BRUZ, the MAX4523ESE+T uniquely balances NO/NC duality, ultra-low power, and proven pin compatibility - making it optimal for space-constrained, battery-aware designs requiring fail-safe analog routing without redesigning PCB layouts.

FAQ
What is the maximum supply voltage range supported by the MAX4523ESE+T?
The MAX4523ESE+T operates from ±2V to ±6V dual supplies or +2V to +12V single supply. Absolute maximum ratings specify V+ to V− differential ≤13.0V - critical when using ±5% tolerance supplies to avoid overstress. At +5V single supply, MAX4523ESE+T maintains 250Ω typical on-resistance and full TTL/CMOS logic compatibility.
How does the MAX4523ESE+T differ from the MAX4521ESE+T and MAX4522ESE+T?
The MAX4523ESE+T integrates two normally open (NO) and two normally closed (NC) switches in one package, whereas MAX4521ESE+T has four NC-only and MAX4522ESE+T has four NO-only channels. This hybrid configuration enables unique fail-safe routing - e.g., default audio path via NC channels while NO channels handle auxiliary inputs - a capability neither MAX4521ESE+T nor MAX4522ESE+T provides.
Is the MAX4523ESE+T pin-compatible with industry-standard analog switches?
Yes, the MAX4523ESE+T is explicitly pin-compatible with DG211, DG212, and DG213 quad SPST analog switches in SOIC-16 packages. Pin mapping for COM, IN, NO/NC, V+, V−, and GND matches these legacy devices - allowing direct replacement without PCB modification, provided thermal and decoupling design rules are observed.
What is the significance of break-before-make timing in the MAX4523ESE+T?
Break-before-make (BBM) timing - specified as 5–20ns for MAX4523ESE+T - ensures that one switch opens before another closes during channel transitions. This prevents momentary short-circuits between signal sources, which is essential in audio routing (avoiding pops) and sensor multiplexing (preventing cross-talk or loading conflicts). BBM is inherent to the MAX4523 variant and not present in MAX4521/MAX4522.
Can the MAX4523ESE+T operate from a +3V supply, and what performance trade-offs apply?
Yes, the MAX4523ESE+T is fully specified for +2.7V to +3.6V single-supply operation. At +3V, on-resistance increases to 600Ω max (vs. 100Ω at ±5V), turn-on time extends to 300ns max, and analog signal range narrows to 0–3V. However, logic thresholds remain compatible (0.8V/2.4V), and leakage stays below 10nA - making it viable for ultra-low-power portable designs where speed and RON are secondary to energy efficiency.
