Product details
Overview
The MAX4523CEE+T 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 delivers 100Ω max on-resistance at ±5V supplies, 4Ω max channel matching, and <1µW quiescent power - enabling precision signal path control in battery-powered audio and data acquisition circuits.
For engineers reviewing the MAX4523CEE+T datasheet, MAX4523CEE+T pinout, MAX4523CEE+T application, or MAX4523CEE+T equivalent, key selection criteria include its dual-supply (±2V to ±6V) or single-supply (+2V to +12V) flexibility, TTL/CMOS-compatible logic thresholds, break-before-make timing (5–20ns), and QSOP-16 package compatibility with industry-standard DG211/DG212/DG213 footprints.
Technical Context
The MAX4523CEE+T implements four independent CMOS transmission gates using complementary N- and P-channel MOSFETs driven by level-shifted logic, enabling true bidirectional rail-to-rail analog signal handling across V− to V+. Its internal logic translators accept 0.8V/2.4V thresholds for TTL/CMOS compatibility under ±5V or +5V supply conditions.
Each channel features matched on-resistance flatness (≤12Ω over signal range) and low charge injection (≤5pC), critical for minimizing glitch energy in sampling and multiplexing applications. The device includes >2kV ESD protection per Method 3015.7 and operates across 0°C to +70°C ambient temperature.
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/phase matching in multi-channel signal routing |
| On-resistance flatness (RFLAT) | 12Ω max over full signal range - maintains consistent insertion loss across rail-to-rail input voltages |
| Off-leakage current | 1nA at +25°C, 10nA at +85°C - preserves signal integrity in high-impedance sensor interfaces |
| Logic thresholds | VIN_L = 0.8V, VIN_H = 2.4V - guarantees reliable switching with standard TTL/CMOS outputs |
| Break-before-make delay | 5–20ns (MAX4523 only) - prevents momentary short-circuit during channel switching |
| Supply range | ±2V to ±6V dual or +2V to +12V single - supports portable, industrial, and mixed-signal system architectures |
Pinout & Package
MAX4523CEE+T uses a 16-pin QSOP package (E16-4), 3.9mm × 4.9mm body, 0.635mm pitch, with exposed pad connected to V+ for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16, 9, 8 | IN1–IN4 | Digital control inputs - active-high logic drives corresponding switch state (NO/NC) |
| 2, 15, 10, 7 | COM1–COM4 | Analog common terminals - bidirectional signal path connection point for each switch |
| 3, 6 | NO1, NO4 | Normally open analog terminals - connect to COM when IN = HIGH (channels 1 & 4) |
| 14, 11 | NC2, NC3 | Normally closed analog terminals - connect to COM when IN = LOW (channels 2 & 3) |
| 4 | V− | Negative analog supply - sets lower analog signal limit; tie to GND for single-supply operation |
| 5 | GND | Digital ground reference - separate from analog signal path; no analog current return path |
| 12 | V+ | Positive analog/digital supply - powers internal logic and switch drivers; substrate-connected |
| 13 | N.C. | No internal connection - must be left unconnected or tied to V+ per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for full-scale sensor and audio signal routing |
| Low charge injection (≤5pC) | Minimizes voltage glitch on sampled nodes - improves accuracy in sample-and-hold and ADC front-end designs |
| Pin compatibility with DG211/DG212/DG213 | Enables drop-in replacement in legacy designs without PCB rework - reduces qualification time and cost |
| TTL/CMOS logic compatibility | Operates reliably with standard digital I/O levels at ±5V or +5V supply - eliminates need for level-shifting circuitry |
| ESD protection >2kV (Method 3015.7) | Withstands handling and board-level ESD events - improves manufacturing yield and field reliability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4522CEE+T | Four NO switches (vs. MAX4523's 2NO/2NC); identical RON, leakage, and timing specs | Suitable where all channels require normally-open behavior (e.g., enable-only signal gating) | Select MAX4522CEE+T when uniform NO configuration simplifies control logic and PCB layout |
| ADG1412BRUZ | 4-channel, 12Ω typical RON, ±15V supply capable, higher 250mA continuous current rating | Better suited for high-voltage industrial I/O modules requiring wider signal swing and fault tolerance | Choose ADG1412BRUZ when operating beyond ±6V or needing higher current drive capability |
Compared with MAX4522CEE+T (all-NO) and ADG1412BRUZ (higher-voltage, higher-current), the MAX4523CEE+T uniquely balances mixed NO/NC topology, ultra-low leakage, and QSOP-16 footprint - making it optimal for compact, low-power multiplexer designs requiring fail-safe signal routing.

FAQ
What supply voltage ranges does the MAX4523CEE+T support?
The MAX4523CEE+T supports dual supplies from ±2V to ±6V or a single supply from +2V to +12V. It is fully specified for operation at +2.7V single supply. The absolute maximum V+ to V− differential is 13.0V - caution is required with ±6V supplies due to potential 13.2V overshoot from ±10% tolerance.
How does the MAX4523CEE+T differ from the MAX4521CEE+T and MAX4522CEE+T?
The MAX4523CEE+T integrates two normally open (NO) and two normally closed (NC) switches in one package. In contrast, MAX4521CEE+T contains four NC switches, and MAX4522CEE+T contains four NO switches. All three share identical electrical specs (RON, leakage, timing) and pinout, enabling flexible signal routing topologies without changing layout.
What is the purpose of the N.C. pin (pin 13) on the MAX4523CEE+T?
Pin 13 on the MAX4523CEE+T is labeled N.C. (No Connection) and has no internal connection. Per Maxim's datasheet guidance, it should remain unconnected or optionally tied to V+ to improve thermal conduction via the package's exposed pad structure - but it must never be used as a signal or supply node.
Does the MAX4523CEE+T require external level shifters when interfacing with 3.3V microcontrollers?
No. The MAX4523CEE+T features TTL/CMOS-compatible logic thresholds (VIN_L = 0.8V, VIN_H = 2.4V) that are fully compatible with 3.3V microcontroller GPIO outputs. When powered from +3.3V or +5V supply, no external level shifter is needed - direct connection suffices for reliable switching.
What is the significance of break-before-make timing in the MAX4523CEE+T?
The MAX4523CEE+T provides guaranteed break-before-make timing (5–20ns) exclusively for its mixed NO/NC configuration - preventing momentary short-circuits during channel transitions. This feature is absent in MAX4521/MAX4522 and is critical in applications like audio crosspoint switching or redundant signal path selection where signal integrity during transition is paramount.
