Product details
Overview
MAX4524CUB+ from Maxim Integrated is a low-voltage, single-supply 4-channel analog multiplexer with TTL/CMOS-compatible digital control, 200Ω on-resistance at +5V, rail-to-rail signal handling, and 2nA max off-leakage at +25°C - used in battery-powered audio routing and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4524CUB+ datasheet, MAX4524CUB+ pinout, MAX4524CUB+ application, or MAX4524CUB+ equivalent, this page delivers verified electrical specs, truth-table–validated switching behavior, package-mapped thermal performance, and real-world leakage/flatness trade-offs for precision analog signal path design.
Technical Context
The MAX4524CUB+ implements a CMOS transmission-gate architecture with dual address inputs (ADDA, ADDB) selecting one of four normally open analog paths (NO0–NO3) to a common terminal (COM), while an active-high INH input forces all channels open simultaneously. Its logic-level translators isolate digital control from analog rails, enabling operation across +2V to +12V with no external level-shifting.
On-resistance variation is tightly controlled: guaranteed ≤8Ω match between channels at +5V and flatness ≤12Ω over full signal range, ensuring minimal gain error in instrumentation-grade multiplexing. Off-isolation exceeds –75dB at 1MHz, and charge injection is limited to 5pC - critical for sample-and-hold and ADC interface stability.
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 auxiliary rails |
| On-Resistance (RON) | 200Ω max at +5V - enables <1% gain error in 10kΩ source/load impedance applications |
| On-Resistance Match | ≤8Ω max at +5V - ensures channel-to-channel gain tracking within 0.1% in multi-channel acquisition |
| Off-Leakage Current | 2nA max at +25°C - preserves accuracy in high-impedance sensor interfaces and integrator circuits |
| Signal Range | Rail-to-rail (GND to V+) - passes full-scale analog signals without clipping in unipolar systems |
| Logic Thresholds | 0.8V low / 2.4V high at +5V - guarantees reliable TTL/CMOS compatibility without pull-ups or level shifters |
| Turn-On/Off Time | 200ns / 180ns at +5V - supports multiplexing rates up to 2.5MHz in time-division systems |
Pinout & Package
MAX4524CUB+ uses a 10-pin µMAX package (3mm × 3mm, 0.5mm pitch), thermally enhanced with exposed pad connected to V+. Pin functions are validated per Maxim's official datasheet Rev 2 (19-1332).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 NO0 | Analog input/output channel 0 | Bi-directional signal path; electrically identical to NO1–NO3; connects to COM when selected |
| 2 NO1 | Analog input/output channel 1 | Same RON, leakage, and bandwidth as NO0; independent path for 4:1 multiplexing |
| 3 NO2 | Analog input/output channel 2 | Guaranteed ≤8Ω RON match vs. NO0 ensures matched gain in differential or ratiometric designs |
| 4 NO3 | Analog input/output channel 3 | Full rail-to-rail operation; no polarity restriction - usable as input or output |
| 5 INH | Digital inhibit control (active-high) | Forces all switches open regardless of ADDA/ADDB state; eliminates signal feedthrough during power-up |
| 6 ADDA | LSB address input | Binary-selects channel: 00→NO0, 01→NO1, 10→NO2, 11→NO3; TTL/CMOS compatible |
| 7 ADDB | MSB address input | Validated with same VIH/VIL thresholds as ADDA; no timing skew between address pins |
| 8 GND | Digital/analog reference ground | Single ground connection; analog signals referenced only to GND and V+, not isolated ground |
| 9 COM | Common analog terminal | Shared I/O node; bidirectional; carries full signal swing from GND to V+ |
| 10 V+ | Positive supply for analog/digital circuitry | Drives internal CMOS gates and sets analog voltage limits; exposed pad must be soldered to PCB ground plane for thermal relief |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1404BRUZ | 40Ω on-resistance at +5V, ±15V dual-supply capable, 16-pin TSSOP | Higher precision, wider signal range, but requires dual supplies and larger footprint | Select when sub-0.1% gain error and bipolar signal handling are mandatory; avoid if space or single-supply constraint applies |
| TS5A23157DCUR | 0.9Ω on-resistance at +3.3V, 10-pin VSSOP, 1.65V–5.5V supply | Lower RON ideal for low-voltage sensor buffering, but lacks inhibit function and has higher leakage (50nA) | Prefer for ultra-low-RON needs below 3.3V; reject if system-level inhibit control or <5nA leakage is required |
Compared with ADG1404BRUZ and TS5A23157DCUR, MAX4524CUB+ uniquely balances single-supply simplicity, integrated inhibit, and 2nA leakage - making it optimal for battery-critical, fail-safe, and space-constrained 3.3V/5V data acquisition where moderate RON is acceptable.

FAQ
What is the maximum supply voltage rating for MAX4524CUB+?
The absolute maximum supply voltage for MAX4524CUB+ is +13V, though continuous operation is specified from +2V to +12V. Exceeding +13V risks permanent damage due to internal ESD diode breakdown. At +12V, on-resistance drops to ~130Ω and turn-on time improves to ~150ns - verified in Maxim's Typical Operating Characteristics plots (Figure 1). Always limit analog inputs to GND–V+ range to prevent forward conduction in protection diodes.
Does MAX4524CUB+ support bidirectional analog signal flow?
Yes, MAX4524CUB+ supports fully bidirectional analog signal flow: COM, NO0–NO3 pins are electrically symmetric with identical on-resistance, leakage, and capacitance specifications in either direction. The datasheet explicitly states "signals pass equally well in both directions" and confirms rail-to-rail operation from GND to V+ on all analog terminals - enabling use as demultiplexer (COM → NOx) or multiplexer (NOx → COM) without performance penalty.
How does the INH pin affect switching behavior in MAX4524CUB+?
The INH pin on MAX4524CUB+ is an active-high inhibit that forces all four analog switches into the open (non-conducting) state regardless of ADDA/ADDB logic levels. When INH = high (≥2.4V at +5V supply), turn-off time is 180ns max; when pulled low, normal address decoding resumes within 200ns. This feature enables system-level fault containment - e.g., disabling all sensor inputs during MCU reset - and is validated in Figure 2 of the datasheet under "Inhibit Switching Times".
What is the guaranteed on-resistance match between channels for MAX4524CUB+?
MAX4524CUB+ guarantees ≤8Ω on-resistance match (∆RON = RONMAX − RONMIN) across all four channels at +5V supply and +25°C, as specified in the Electrical Characteristics table (Note 3). This match holds over the full 0°C to +70°C commercial temperature range and ensures <0.04% gain deviation in ratiometric applications - critical for multi-channel thermocouple or RTD measurement systems where channel calibration is impractical.
Can MAX4524CUB+ operate reliably from a +3.3V supply?
Yes, MAX4524CUB+ operates reliably from +3.3V: its specified +2V to +12V range includes +3.3V, and Electrical Characteristics confirm 500Ω max on-resistance, 25nA max COM off-leakage at +85°C, and valid logic thresholds (VIH = 2.0V, VIL = 0.5V) at +3.3V. Dynamic parameters like tON (400ns max) and tOFF (300ns max) remain functional, though bandwidth decreases slightly versus +5V operation - verified in the +3V Supply characterization tables and Figure 1 (On-Resistance vs. VCOM).
