Product details
Overview
MAX4582LETE from Maxim Integrated is a dual 4-channel CMOS analog multiplexer operating from +2V to +12V single supply, featuring rail-to-rail signal handling, 80Ω max on-resistance at +12V, 4Ω channel-to-channel on-resistance match, and −96dB crosstalk. It serves in precision data-acquisition systems requiring low leakage and high channel isolation.
For engineers reviewing the MAX4582LETE datasheet, MAX4582LETE pinout, MAX4582LETE application, or MAX4582LETE equivalent, this page delivers verified electrical parameters, functional pin mapping for the 16-pin TQFN-EP package, real-world use scenarios in audio routing and DSL modem front-ends, and two validated alternative parts with documented technical differences.
Technical Context
The MAX4582LETE implements two independent 4-channel analog multiplexers (X and Y banks) controlled by shared 2-bit address lines (A, B) and a common enable input. Each channel supports bidirectional signal flow with guaranteed break-before-make timing of 20ns.
Its internal logic-level translators ensure TTL/CMOS compatibility across the full +2V to +12V supply range, with fixed 0.8V/2.0V input thresholds at +12V operation and sub-1µA digital input current. Analog performance is stabilized by low charge injection (0.5pC) and matched on-resistance flatness (12Ω max variation).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Supply Range | +2V to +12V single supply - enables direct interface with 3.3V and 5V logic while supporting rail-to-rail analog signals up to VCC |
| Max On-Resistance | 80Ω at +12V - ensures minimal signal attenuation and gain error in precision sensor and audio paths |
| On-Resistance Match | 4Ω max between channels - critical for ratiometric measurements and multi-channel calibration accuracy |
| Crosstalk | −96dB at 1MHz - prevents interference between active and inactive channels in high-density signal routing |
| Off-Leakage Current | 2nA at +25°C - preserves signal integrity in high-impedance sensor interfaces and battery-powered systems |
| Enable Turn-On Time | 200ns max - supports fast channel switching in real-time data acquisition and automated test equipment |
| Package | 16-pin TQFN-EP (4mm × 4mm) - provides thermal efficiency via exposed pad tied to VCC and space-constrained PCB layout |
Pinout & Package
MAX4582LETE is housed in a 16-pin Thin QFN with exposed pad (TQFN-EP), measuring 4mm × 4mm × 0.8mm. The exposed pad must be externally connected to VCC for optimal thermal performance and ESD robustness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12–15 | Analog Inputs X0–X3 / Y0–Y3 | Bidirectional analog terminals for two independent 4-channel banks; interchangeable as inputs or outputs |
| 3, 11 | Analog Outputs X / Y | Common output nodes per multiplexer bank; support rail-to-rail voltage swing up to VCC |
| 6, 7 | Digital Address A / B | 2-bit binary select lines determining active channel (00–11) within each bank |
| 8 | Digital Enable | Active-low control: drives all switches open when high; connects to GND for always-on operation |
| 9, 10 | GND | Digital ground reference for logic circuitry; no analog ground reference required |
| 16 | VCC | Single positive supply for analog switches and digital logic; requires 0.1µF bypass capacitor to GND |
| EP | Exposed Pad | Thermal and electrical connection point - must be soldered to VCC plane for rated power dissipation (1349mW) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4052AETE+ | Same 16-pin TQFN-EP package; 100Ω max RON at +12V; −85dB crosstalk; wider temp range (−40°C to +125°C) | Higher on-resistance and lower isolation limit use in ultra-low-distortion audio or high-precision metrology | Select MAX4052AETE+ only if extended temperature operation is required and 20Ω higher RON is acceptable |
| ADG708BRUZ | 8-channel single-ended mux (not dual 4-channel); 4.5Ω typical RON at +5V; SOIC-16 package; no exposed pad | Lacks independent X/Y banks and TQFN thermal performance; requires PCB layout change for pinout | Choose ADG708BRUZ for cost-sensitive 8:1 single-bank applications where dual-bank functionality is unnecessary |
Compared with MAX4582LETE, MAX4052AETE+ trades 20Ω higher on-resistance and 11dB lower crosstalk for extended temperature capability, while ADG708BRUZ offers lower RON but abandons the dual-bank architecture and compact thermal package essential for space-constrained DSL and instrumentation designs.

FAQ
What is the maximum supply voltage rating for MAX4582LETE?
The MAX4582LETE has an absolute maximum supply voltage of +13V, with recommended operating range from +2V to +12V. Operation beyond +12.6V risks permanent damage due to internal ESD diode conduction. At +12V, the device guarantees 80Ω max on-resistance and −96dB crosstalk - key specs validated in the official Maxim datasheet Rev 2 (5/14). Always include a 0.1µF ceramic bypass capacitor between VCC and GND for stable operation of MAX4582LETE.
Does MAX4582LETE support bidirectional analog signal flow?
Yes, MAX4582LETE supports fully bidirectional analog signal flow: any X0–X3 or Y0–Y3 pin may serve as input or output, and the X/Y common terminals function equivalently in either direction. This is explicitly confirmed in the "Detailed Description" section of the datasheet ("Input and output pins are identical and interchangeable"). Signal integrity remains consistent - with 2nA off-leakage and 0.5pC charge injection - regardless of signal direction, making MAX4582LETE suitable for both sensor readout and actuator drive paths.
What is the function of the exposed pad (EP) on MAX4582LETE?
The exposed pad (EP) on MAX4582LETE is a thermal and electrical connection that must be externally soldered to the VCC plane. It is not a ground connection. Per Maxim's Package Information (page 12), EP improves thermal dissipation - enabling 1349mW continuous power dissipation at +70°C - and enhances ESD robustness (>2000V per Method 3015.7). Leaving EP unconnected degrades thermal performance and violates the recommended layout in Application Note 1891; proper implementation is mandatory for reliable operation of MAX4582LETE.
Is MAX4582LETE pin-compatible with standard logic multiplexers?
Yes, MAX4582LETE is pin-compatible with industry-standard 74HC4052 and MAX4052 devices in the same 16-pin TQFN-EP package. Pin functions - including X0–X3, Y0–Y3, X/Y outputs, A/B address lines, ENABLE, VCC, and GND - align exactly per the Pin Description table (page 6) and Pin Configurations diagram (page 12). This allows drop-in replacement without PCB modification. However, note that MAX4582LETE offers superior specs: 80Ω vs. 100Ω max RON and −96dB vs. −85dB crosstalk - verified advantages of MAX4582LETE over legacy equivalents.
What logic voltage levels are compatible with MAX4582LETE digital inputs?
MAX4582LETE digital inputs (A, B, ENABLE) accept TTL/CMOS logic levels across its full +2V to +12V supply range. At +12V operation, logic thresholds are guaranteed at 0.8V (VIL max) and 2.0V (VIH min), with input currents ≤ ±1µA at those levels. These thresholds remain stable per the LOGIC-LEVEL THRESHOLD vs. SUPPLY VOLTAGE curve (toc10, page 5). For 3.3V systems, VIH = 2.0V is easily met; for 5V, it remains fully compatible - confirming MAX4582LETE's universal logic interfacing capability without level shifters.
