Product details
Overview
MAX4523CEE 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 (±5V supplies), 4Ω max channel matching, 12Ω max on-resistance flatness, and <1µW power consumption. It supports dual supplies (±2V to ±6V) or single +2.7V–+12V operation and is used in audio signal routing, data acquisition, and battery-powered test equipment.
For engineers reviewing the MAX4523CEE datasheet, MAX4523CEE pinout, MAX4523CEE application, or MAX4523CEE 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), ESD robustness (>2kV), and QSOP-16 package compatibility with industry-standard DG211/DG212/DG213 layouts.
Technical Context
The MAX4523CEE implements four independent CMOS SPST switches using complementary N- and P-channel MOSFETs driven by level-translated logic inputs. Its internal architecture enables true rail-to-rail analog signal handling across V− to V+, with leakage currents tightly controlled via matched ESD diode biasing.
It integrates logic-level translators that accept TTL/CMOS inputs at ±5V or +5V supply and generate gate drive signals referenced to V+ and V−, ensuring consistent switching performance across supply configurations. The device's break-before-make behavior (exclusive to MAX4523 variants) prevents momentary shorting during channel 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 - critical for balanced gain/phase in multi-channel signal routing or differential applications. |
| On-resistance flatness (RFLAT) | 12Ω max over signal range - maintains consistent insertion loss across full analog input swing (e.g., ±4.5V). |
| Off-leakage current | 1nA at +25°C, 10nA at +85°C - preserves signal integrity in high-impedance sensor interfaces and battery-critical standby modes. |
| Logic thresholds | +0.8V low / +2.4V high - guarantees reliable TTL/CMOS compatibility without external level-shifting at +5V supply. |
| Break-before-make delay | 5–20 ns (typ. 10 ns) - prevents transient conduction between NC and NO paths during switching, essential for fault-tolerant signal selection. |
| ESD protection | >2kV per Method 3015.7 - enhances reliability in handheld test gear and avionics where static discharge is common. |
Pinout & Package
MAX4523CEE is housed in a 16-pin QSOP package (E16-4), 3.9mm × 4.9mm body, 0.635mm pitch, with exposed pad connected to V+ for thermal and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3, IN4 | Digital control inputs | Active-high logic controls individual switch states; IN1/IN4 enable NO1/NO4, IN2/IN3 enable NC2/NC3. |
| COM1–COM4 | Analog common terminals | Signal bidirectional ports - each connects to either NO or NC path depending on logic state. |
| NO1, NO4 | Normally open analog terminals | Open-circuit when IN = 0; connect to COM1/COM4 only when corresponding IN = 1. |
| NC2, NC3 | Normally closed analog terminals | Connected to COM2/COM3 when IN = 0; disconnect when IN = 1 - provides default-path continuity. |
| V+, V− | Analog supply rails | Set analog signal range (V− to V+); V− tied to GND for single-supply operation; substrate tied to V+. |
| GND | Digital ground reference | Reference for logic inputs only; no analog signal reference - analog paths are fully floating between V+ and V−. |
| N.C. | No connection | Pins 10 and 12 are unconnected internally - must be left floating or grounded per layout best practice. |
Key Features
| Feature | Design Value |
|---|---|
| Mixed NO/NC configuration | Two NO (pins NO1/NO4) and two NC (pins NC2/NC3) switches enable fail-safe routing - e.g., default audio path remains active during microcontroller reset. |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ (e.g., ±4.5V or 0V to +5V), eliminating clipping in wide-dynamic-range sensor or audio front-ends. |
| Low power consumption | <1µW quiescent power (I+ and I− < 1µA) extends battery life in portable DMMs and handheld analyzers. |
| Pin compatibility | Direct replacement for DG211/DG212/DG213 in QSOP-16 footprint - enables drop-in upgrade with improved on-resistance matching and ESD rating. |
| Break-before-make timing | Guaranteed 5–20 ns delay prevents overlap between NC and NO conduction - avoids short-circuits in multiplexed power or signal distribution. |
Applications
| Audio Signal Routing | Data Acquisition |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4522CEE | Four NO-only switches (vs. MAX4523CEE's 2NO/2NC); identical RON, leakage, and timing specs. | Suitable where all paths require active-enable behavior; lacks default-closed safety path. | Select MAX4522CEE when system design mandates uniform NO topology and no fail-safe NC requirement. |
| ADG1412BRUZ | Quad SPST, 1.5Ω typical RON (lower), but only NO configuration; requires ≥±4.5V dual or ≥9V single supply. | Better performance in low-RON precision instrumentation; incompatible with +2.7V or ±2V operation. | Choose ADG1412BRUZ only if supply headroom allows ≥±4.5V and sub-2Ω RON justifies higher cost and voltage constraints. |
Compared with MAX4522CEE and ADG1412BRUZ, the MAX4523CEE uniquely delivers mixed NO/NC functionality within ultra-low-voltage operation (down to +2.7V), making it irreplaceable in battery-powered systems requiring both active-select and default-path redundancy without supply overhead.

FAQ
What is the maximum supply voltage range supported by the MAX4523CEE?
The MAX4523CEE operates with dual supplies from ±2V to ±6V (V+ to V− differential ≤13.0V) or a single supply from +2.7V to +12V. At ±5V, it achieves 100Ω max on-resistance; at +3V, RON rises to 600Ω. Absolute maximum ratings specify V+ to GND ≤+13.0V and V− to GND ≥−13.0V. Exceeding these risks permanent damage.
Does the MAX4523CEE support rail-to-rail analog signal operation?
Yes, the MAX4523CEE supports true rail-to-rail analog signal operation between V− and V+. With ±5V supplies, signals from −4.5V to +4.5V pass without clipping; with +5V single supply (V− = GND), signals from 0V to +4.5V are fully supported. This is enabled by its CMOS transmission-gate architecture and level-translated gate drive.
How does the mixed NO/NC configuration of the MAX4523CEE benefit system design?
The MAX4523CEE's two NO (NO1/NO4) and two NC (NC2/NC3) switches enable fail-safe signal routing - e.g., NC paths maintain default connections during power-up, reset, or MCU failure, while NO paths activate only on command. This eliminates need for external pull-up/down components and simplifies safety-critical designs in test gear and avionics.
What is the significance of the break-before-make timing in the MAX4523CEE?
The MAX4523CEE guarantees 5–20 ns break-before-make delay between NC and NO paths during switching. This prevents momentary short-circuits when reconfiguring signal paths - critical in applications like range selection in multimeters or source switching in power supplies where overlapping conduction could damage downstream circuitry or cause measurement errors.
Is the MAX4523CEE pin-compatible with legacy industry-standard analog switches?
Yes, the MAX4523CEE in QSOP-16 (E16-4) is pin-compatible with DG211, DG212, and DG213 in the same package. Pin assignments for INx, COMx, V+, V−, GND, and N.C. match exactly. This allows direct drop-in replacement with improved specifications: lower on-resistance matching (4Ω vs. typical 15Ω), higher ESD rating (>2kV vs. ~2kV), and guaranteed break-before-make timing not present in DG-series parts.
