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.
Technical Context
The MAX4523CSE+ implements four independent CMOS transmission gates-two configured as NO and two as NC-each driven by logic-level translators that convert TTL/CMOS inputs into complementary V+/V− gate signals. Its analog path uses paralleled N- and P-channel MOSFETs to enable rail-to-rail operation across ±5V or +5V supplies.
Internal ESD diodes clamp analog pins to V+ and V−, defining absolute signal limits and contributing to leakage current behavior. Off-isolation exceeds −90 dB at 100 kHz, and crosstalk remains below −90 dB, supporting high-fidelity signal switching in mixed-signal systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100 Ω max at ±5V - ensures minimal voltage drop and signal attenuation in precision analog paths |
| On-resistance match (ΔRON) | 4 Ω max between channels - enables matched gain/attenuation in differential or multi-path routing |
| On-resistance flatness (RFLAT) | 12 Ω max over signal range - maintains consistent insertion loss across full analog input swing |
| Off-leakage current | 10 nA max at +85°C - preserves signal integrity in high-impedance sensor or sample-hold circuits |
| Break-before-make delay (tBBM) | 5–20 ns (MAX4523 only) - prevents momentary shorting during channel reconfiguration |
| Logic thresholds | +0.8V low / +2.4V high - guarantees reliable TTL/CMOS interfacing without level-shifting |
| ESD protection | >2 kV per Method 3015.7 - enhances robustness in handling-sensitive industrial and portable environments |
Pinout & Package
MAX4523CSE+ is housed in a 16-pin narrow SOIC (S16-2) package with exposed pad (not connected to internal circuitry per datasheet; EP connects to V+).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16, 9, 8 | IN1–IN4 | Digital control inputs; active-high logic drives corresponding switch state |
| 2, 15, 10, 7 | COM1–COM4 | Common analog terminals; bidirectional signal path interface for all switches |
| 3, 6 | NO1, NO4 | Normally open analog terminals; connect to COM when IN = high |
| 14, 11 | NC2, NC3 | Normally closed analog terminals; disconnect from COM when IN = high |
| 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 | N.C. | No internal connection - must be left unconnected |
| 13 | V+ | Positive supply rail; powers analog switches and internal logic; internally tied to substrate |
Key Features
| Feature | Design Value |
|---|---|
| Mixed NO/NC configuration | Two NO and two NC switches enable flexible signal path control (e.g., default-closed safety path + selectable alternate path) |
| Rail-to-rail analog operation | Supports full V− to V+ signal swing - eliminates clipping in ±5V or +3V to +12V systems |
| Low charge injection (1–5 pC) | Minimizes voltage glitch on sampled nodes - critical for precision ADC front-ends and sample-hold circuits |
| Pin compatibility with DG211/DG212/DG213 | Enables drop-in replacement in legacy designs without PCB revision |
| Ultra-low power (<1 µW) | Reduces quiescent load in battery-powered instruments and portable medical devices |
Applications
| Audio Signal Routing | Data Acquisition Systems |
|---|---|
Use Scenario: Selecting between microphone inputs or routing line-level signals in portable audio mixers. IC Role / Device Role / Timing Role: Quad SPST switch providing low-distortion, low-crosstalk analog path selection with break-before-make timing. Use Value: 100Ω RON and <−90 dB off-isolation preserve THD performance; 1–5 pC charge injection prevents pop/click artifacts. |
Use Scenario: Multiplexing sensor outputs (thermocouples, strain gauges) into a shared ADC channel. IC Role / Device Role / Timing Role: Precision analog switch enabling sequential sampling with matched channel resistance and minimal leakage. Use Value: 4Ω max RON matching ensures consistent gain scaling; 10nA max off-leakage avoids DC offset errors at high source impedances. |
| Battery-Operated Test Equipment | Avionics Signal Conditioning |
Use Scenario: Configuring measurement ranges (voltage/current/divider networks) in handheld multimeters. IC Role / Device Role / Timing Role: Low-power, rail-to-rail analog switch managing signal path topology under tight energy budgets. Use Value: <1 µW quiescent power extends battery life; ±2V to ±6V dual-supply support enables bipolar signal handling without external rails. |
Use Scenario: Isolating redundant sensor channels or selecting primary/backup flight control signals. IC Role / Device Role / Timing Role: Robust analog switch with >2kV ESD protection and guaranteed operation from −40°C to +85°C. Use Value: Industrial-grade temperature rating and high off-isolation (>−90 dB) ensure signal integrity in safety-critical avionics subsystems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4522CSE+ | Four NO-only channels; identical RON, leakage, timing, and package - no NC functionality | Suitable where all paths require active closure; not usable where default-closed paths are needed | Select MAX4522CSE+ only when full NO configuration suffices and NC capability is unnecessary |
| ADG1412BRUZ | Quad SPST, 1.5Ω typical RON (vs. 100Ω), ±15V supply capable, higher cost, TSSOP-16 | Better for low-RON, high-voltage industrial PLC I/O; less suitable for low-power portable designs | Choose ADG1412BRUZ when sub-2Ω on-resistance or ±15V operation is required - not a direct replacement |
Compared with MAX4522CSE+, MAX4523CSE+ provides essential NC functionality for fail-safe or default-path designs; versus ADG1412BRUZ, it trades lower RON and wider voltage range for significantly lower cost, lower power, and proven suitability in portable and battery-constrained systems.

FAQ
What is the operating temperature range for MAX4523CSE+?
The MAX4523CSE+ is specified for commercial temperature operation from 0°C to +70°C. This range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet. The 'C' prefix in MAX4523CSE+ explicitly denotes the 0°C to +70°C grade. For extended temperature versions, consider MAX4523ESE+ (−40°C to +85°C) or MAX4523MJE (−55°C to +125°C).
Does MAX4523CSE+ support single-supply operation?
Yes, MAX4523CSE+ supports single-supply operation from +2V to +12V. In this mode, the V− pin must be connected to GND. Electrical characteristics are fully specified down to +2.7V, with typical on-resistance of 250Ω at +5V and 600Ω at +3V. Rail-to-rail analog signal handling is maintained across the full supply range.
What is the function of the N.C. pin (pin 12) on MAX4523CSE+?
Pin 12 on MAX4523CSE+ is labeled N.C. (No Connection) and is not internally connected. The datasheet explicitly states "N.C. = NOT CONNECTED" and confirms in the Pin Description table that this pin has no internal bond wire or circuit connection. It must be left floating or grounded per PCB layout best practices - but never driven or used as a signal path.
How does the break-before-make timing work in MAX4523CSE+?
Break-before-make (BBM) timing applies only to the two NO switches (pins NO1/NO4) and two NC switches (pins NC2/NC3) in MAX4523CSE+. When toggling between complementary pairs (e.g., IN1 high → IN1 low), tBBM ensures the NC path opens before the NO path closes, preventing momentary shorting. Datasheet specifies tBBM as 5–20 ns at +25°C with V+ = +5.5V and V− = −5.5V.
Is MAX4523CSE+ pin-compatible with industry-standard analog switches?
Yes, MAX4523CSE+ is explicitly stated as pin-compatible with DG211, DG212, and DG213 analog switches. This compatibility covers identical pin functions (IN, COM, NO/NC, V+, V−, GND, N.C.) and mechanical footprint in the 16-pin SOIC package. No PCB layout changes are required for drop-in replacement in existing DG-series designs.
