Product details
Overview
MAX4524CPD from Maxim Integrated is a low-voltage, single-supply 4-channel analog multiplexer/demultiplexer IC with TTL/CMOS-compatible digital control, 200Ω on-resistance at +5V, rail-to-rail signal handling, and an inhibit input that simultaneously opens all channels. It serves as a precision signal-routing switch in battery-powered instrumentation and portable audio systems.
For engineers reviewing the MAX4524CPD datasheet, MAX4524CPD pinout, MAX4524CPD application, or MAX4524CPD equivalent, this device is selected for low-leakage (2nA max COM off-leakage), tight on-resistance matching (8Ω guaranteed match), and stable operation across +2V to +12V supplies - critical for low-power data acquisition and mixed-signal interface design.
Technical Context
The MAX4524CPD implements a CMOS transmission-gate architecture with dual-level logic translators, enabling full rail-to-rail analog conduction while maintaining TTL/CMOS compatibility at +5V. Its inhibit function gates all internal switch paths via a dedicated INH pin tied to GND for activation.
On-resistance varies predictably with supply voltage (200Ω @ +5V, 500Ω @ +3V) and analog common-mode voltage, with flatness ≤12Ω over 0–3V range. Leakage performance is specified across temperature: 2nA max at +25°C and 20nA max at +85°C for off-state NO/NC terminals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - supports direct integration into 3.3V and 5V systems without level-shifting. |
| On-Resistance (RON) | 200Ω max at +5V - ensures minimal signal attenuation and gain error in precision sensor or audio routing. |
| RON Match | 8Ω max between channels at +5V - enables accurate channel-to-channel signal consistency in multiplexed ADC front-ends. |
| Off-Leakage Current | 2nA max at +25°C - preserves signal integrity in high-impedance sensor nodes and battery-critical standby modes. |
| Analog Signal Range | Rail-to-rail (GND to V+) - allows full dynamic range utilization of ±0.3V to V+–0.3V input signals without clipping. |
| Logic Thresholds | 0.8V to 2.4V at +5V - guarantees reliable switching with standard TTL and CMOS outputs without external biasing. |
| Turn-On/Off Time | 200ns / 180ns (typical, CL = 35pF) - supports multiplexing of DC to ~1MHz signals with minimal settling delay. |
Pinout & Package
MAX4524CPD is housed in a 10-pin PDIP package (0.300" wide), with pin 1 marked by a notch or dot. The package provides through-hole mounting and thermal dissipation suitable for industrial and test equipment environments.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NO0 | Normally open analog input/output terminal for channel 0 - bidirectional signal path controlled by ADDA/ADDB. |
| 2 | NO1 | Normally open analog input/output terminal for channel 1 - shares common COM node; used in 4:1 mux configuration. |
| 3 | NO2 | Normally open analog input/output terminal for channel 2 - electrically identical to NO0–NO3; interchangeable per datasheet note. |
| 4 | NO3 | Normally open analog input/output terminal for channel 3 - completes 4-channel selection matrix with ADDA/ADDB address inputs. |
| 5 | GND | Digital/analog ground reference - no analog signal reference to GND; sets lower bound of analog signal range. |
| 6 | ADDA | LSB address input for channel selection - binary-coded input (with ADDB) determines which NOx connects to COM. |
| 7 | ADDB | MSB address input for channel selection - together with ADDA, selects one of four NO paths to COM (00→NO0, 11→NO3). |
| 8 | INH | Inhibit control input - logic high forces all switches open regardless of address state; active-low functional enable. |
| 9 | COM | Common analog terminal - bidirectional I/O node shared across all four channels; carries routed signal to/from system. |
| 10 | V+ | Positive supply pin - powers internal CMOS switches and logic translators; defines upper analog signal limit (V+ − 0.3V). |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Operates from +2V to +12V - eliminates need for dual supplies in portable or legacy 5V/12V systems. |
| Rail-to-rail analog signal handling | Supports signals from GND to V+ - preserves full dynamic range in sensor interfaces and audio line-level routing. |
| Guaranteed on-resistance match | ≤8Ω max mismatch between channels at +5V - critical for minimizing gain/offset errors in multi-channel data acquisition. |
| TTL/CMOS logic compatibility | 0.8V to 2.4V thresholds at +5V - ensures direct interfacing with microcontrollers, FPGAs, and logic families without buffers. |
| Low off-leakage current | 2nA max at +25°C - maintains accuracy in high-impedance circuits (e.g., pH sensors, photodiode amplifiers) during channel disable. |
Applications
| Battery-Operated Test Equipment | Portable Audio Signal Routing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4524EUB+ | 10-pin µMAX package (3mm × 3mm), -40°C to +85°C temp range, RoHS-compliant - smaller footprint and extended temperature rating. | Suitable for space-constrained industrial controllers and automotive body electronics where extended temperature operation is required. | Select MAX4524EUB+ when PCB real estate is limited and operating ambient exceeds +70°C. |
| ADG1404BRUZ | 4-channel mux with 4.7Ω typical RON, ±15V dual-supply capable, higher bandwidth (170MHz), but requires dual rails and has higher quiescent current (200µA). | Better suited for high-speed test equipment or wide-dynamic-range instrumentation needing sub-5Ω on-resistance and dual-supply flexibility. | Choose ADG1404BRUZ only if RON <5Ω and >10MHz bandwidth are mandatory - not a drop-in replacement due to supply and pinout differences. |
Compared with MAX4524CPD, MAX4524EUB+ offers identical electrical performance in a miniature package with extended temperature support, while ADG1404BRUZ trades single-supply simplicity for lower RON and higher speed - requiring redesign of supply and layout.

FAQ
What is the maximum supply voltage rating for MAX4524CPD?
The MAX4524CPD has an absolute maximum supply voltage of +13V, but its operational range is specified from +2V to +12V. Operating continuously above +12V risks permanent damage. For reliable long-term use, maintain V+ within the recommended +2V to +12V window, with optimal performance observed at +5V and +3V.
Does MAX4524CPD support bidirectional analog signal flow?
Yes, MAX4524CPD supports fully bidirectional analog signal routing. All NOx pins and the COM pin are electrically symmetrical - signals pass with identical on-resistance, leakage, and bandwidth in either direction. This makes MAX4524CPD suitable for both multiplexer (COM → NOx) and demultiplexer (NOx → COM) configurations without performance penalty.
What is the function of the INH pin on MAX4524CPD?
The INH (inhibit) pin on MAX4524CPD is an active-high control input that forces all four analog switches into the open (off) state regardless of ADDA/ADDB address settings. When INH = logic high (≥2.4V at +5V supply), all NOx–COM paths are disconnected. Pulling INH to GND enables normal address-controlled switching.
Can MAX4524CPD operate from a +3.3V supply?
Yes, MAX4524CPD operates reliably from a +3.3V supply. At +3.3V, typical on-resistance is ~350Ω (within the +3V spec of 500Ω max), and logic thresholds adjust to 0.5V (VIL) and 2.0V (VIH). All timing parameters remain functional, though turn-on/off times increase moderately versus +5V operation - verified in the +3V electrical characteristics table.
Is MAX4524CPD pin-compatible with other devices in the MAX4524/MAX4525 family?
MAX4524CPD shares identical pinout and function with all MAX4524 variants (e.g., MAX4524CUB, MAX4524EUB), including the same 10-pin PDIP footprint and signal assignments. However, it is not pin-compatible with MAX4525 (DPDT switch), which uses different internal routing and truth table behavior despite sharing package and pin count.
