Product details
Overview
MAX4524CUB+TGA7 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, 2nA max on-leakage at +25°C, and rail-to-rail analog signal handling capability - used in battery-powered audio routing and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4524CUB+TGA7 datasheet, MAX4524CUB+TGA7 pinout, MAX4524CUB+TGA7 application, or MAX4524CUB+TGA7 equivalent, key selection considerations include on-resistance matching (±8Ω), inhibit-controlled channel shutdown, single +2V to +12V supply operation, and TDFN-EP package thermal performance for space-constrained portable systems.
Technical Context
The MAX4524CUB+TGA7 implements a CMOS transmission-gate architecture with dual-level logic translators that convert 0.8V–2.4V input thresholds into full-rail gate drive signals, enabling robust switching across its entire +2V to +12V supply range. Its internal ESD diodes clamp analog pins to V+ and GND, defining absolute signal limits while contributing to leakage behavior.
It features break-before-make timing (400ns max at +3V) and address transition control (200ns typical at +5V), ensuring glitch-free channel selection. Charge injection is tightly controlled at 0.8–5pC, critical for precision sample-and-hold and ADC interface applications where signal integrity must be preserved during switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V single supply - supports direct integration into 3.3V and 5V systems without level shifters |
| On-Resistance (RON) | 200Ω max at +5V - ensures minimal signal attenuation and gain error in precision analog paths |
| On-Resistance Match (∆RON) | 8Ω max at +5V - enables accurate ratiometric measurements across channels in multiplexed sensor interfaces |
| Off-Leakage Current | 2nA max at +25°C - preserves high-impedance node integrity in battery-operated measurement circuits |
| Logic Thresholds | 0.8V low / 2.4V high at +5V - guarantees reliable TTL/CMOS compatibility without external biasing |
| Charge Injection | 0.8–5pC - limits voltage step errors in switched-capacitor and sampling circuits |
| Turn-On/Off Time | 200ns / 180ns typical at +5V - supports multiplexing rates up to ~2MHz in data-acquisition systems |
Pinout & Package
MAX4524CUB+TGA7 is housed in a 10-pin TDFN-EP (3mm × 3mm) package with exposed pad (EP) connected to V+. The package provides enhanced thermal dissipation (1951mW at +70°C) and compact footprint for portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO0) | Analog Input/Output Channel 0 | Bi-directional normally-open switch terminal - connects to COM when selected via ADDA/ADDB |
| 2 (NO1) | Analog Input/Output Channel 1 | Bi-directional normally-open switch terminal - shares common control logic with NO0–NO3 |
| 3 (NO2) | Analog Input/Output Channel 2 | Bi-directional normally-open switch terminal - supports 4:1 multiplexing with address decoding |
| 4 (NO3) | Analog Input/Output Channel 3 | Bi-directional normally-open switch terminal - completes 4-channel MUX configuration |
| 5 (INH) | Digital Inhibit Control | Active-high logic input - forces all switches open simultaneously for system-level power gating |
| 6 (ADDA) | Address Bit A | LSB of 2-bit binary address - selects one of four NOx paths when INH = low |
| 7 (ADDB) | Address Bit B | MSB of 2-bit binary address - decodes channel selection with ADDA per truth table |
| 8 (GND) | Digital and Analog Reference | Common ground reference for logic and analog domains - no analog signal ground path required |
| 9 (COM) | Common Analog Terminal | Shared bidirectional I/O port - routes selected NOx signal in either direction (MUX or DEMUX mode) |
| 10 (V+) | Positive Supply | Powers internal CMOS switches and logic - sets analog signal rails (GND to V+) and enables ESD protection |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4524ETB+ | Same die, -40°C to +85°C extended temp grade, TDFN-EP package with AAP top mark | Required for industrial or automotive ambient environments beyond 0°C–70°C | Select MAX4524ETB+ when operating above +70°C or below 0°C; otherwise MAX4524CUB+TGA7 suffices for commercial use |
| TMUX1134RSVR | 4-channel MUX with 1.5Ω RON (typ), 1.08V–5.5V supply, but no inhibit pin and higher 10pC charge injection | Lacks global inhibit function; better for low-RON precision apps but less suitable for power-gated systems | Choose TMUX1134RSVR only if ultra-low on-resistance is critical and inhibit control is unnecessary |
Compared with MAX4524ETB+, the MAX4524CUB+TGA7 offers identical functionality at lower cost for commercial-temperature applications, while TMUX1134RSVR trades inhibit capability and leakage performance for lower on-resistance - making MAX4524CUB+TGA7 optimal for battery-powered systems requiring robust shutdown and stable leakage over temperature.

FAQ
What is the maximum supply voltage rating for MAX4524CUB+TGA7?
The MAX4524CUB+TGA7 has an absolute maximum supply voltage of +13V, but its specified operational range is +2V to +12V. Operating at +12V is fully supported per datasheet electrical characteristics, with on-resistance decreasing and leakage increasing predictably within limits. Exceeding +13V risks permanent damage due to internal ESD diode breakdown.
Does MAX4524CUB+TGA7 support bidirectional analog signal flow?
Yes, MAX4524CUB+TGA7 supports fully bidirectional analog signal flow between COM and any NOx terminal. Its CMOS transmission-gate structure imposes no inherent directionality - signals pass equally well from NO0 to COM or COM to NO0, enabling both multiplexer and demultiplexer configurations in the same device.
What is the purpose of the exposed pad (EP) on the MAX4524CUB+TGA7 TDFN package?
The exposed pad (EP) on the MAX4524CUB+TGA7 TDFN package is internally connected to V+ and must be soldered to a V+-referenced copper pour on the PCB. It significantly improves thermal resistance (derating factor 24.4mW/°C above +70°C) and enhances power dissipation capability up to 1951mW, critical for sustained operation in compact enclosures.
Can MAX4524CUB+TGA7 operate reliably at +1.8V supply?
No - MAX4524CUB+TGA7 is not characterized or guaranteed below +2V. While functional operation may occur near +1.7V at room temperature, on-resistance rises sharply, switching times degrade, and logic thresholds become unreliable. For +1.8V systems, consider purpose-designed low-voltage switches like the TMUX1104 instead of MAX4524CUB+TGA7.
How does the INH pin affect leakage performance in MAX4524CUB+TGA7?
When INH is high, all internal switches are forced open, reducing total device current to ~10µA (I+) and lowering effective off-leakage at the COM and NOx terminals. However, individual channel off-leakage specifications (e.g., 2nA at +25°C) apply regardless of INH state - the inhibit function disables conduction paths but does not alter intrinsic junction leakage of unselected terminals.
