Product details
Overview
MAX4582LEEE 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 at 1MHz - used in audio/video routing and data-acquisition systems where low leakage and high isolation are critical.
For engineers reviewing the MAX4582LEEE datasheet, MAX4582LEEE pinout, MAX4582LEEE application, or MAX4582LEEE equivalent, this page delivers verified electrical specs, QSOP-16 pin mapping, real-world use cases in DSL modems and communications circuits, and two validated alternative parts with documented functional and packaging differences.
Technical Context
The MAX4582LEEE implements two independent 4:1 analog multiplexers sharing common address (A/B) and enable inputs, with separate X and Y output buses. Each channel supports bidirectional rail-to-rail analog signals up to VCC, with logic thresholds fixed at 0.8V (VIL) and 2.0V (VIH) for TTL/CMOS compatibility across the full +12V supply range.
Its internal architecture uses matched CMOS transmission gates with integrated level translators, enabling precise channel selection timing (tTRANS ≤ 200ns), fast switching (tON ≤ 200ns), and guaranteed break-before-make operation (tBBM ≥ 20ns). Off-isolation of −90dB and crosstalk of −96dB are measured at 1MHz with 50Ω terminations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V single supply - enables direct interface with 3.3V and 5V logic while supporting rail-to-rail analog input/output swing. |
| Max On-Resistance | 80Ω at +12V - ensures minimal signal attenuation and voltage drop in precision sensor or audio signal paths. |
| On-Resistance Match | ≤4Ω between channels at +25°C - critical for gain-matching in multi-channel instrumentation amplifiers or ADC front-ends. |
| Off-Leakage Current | ±2nA at +25°C - preserves accuracy in high-impedance sensor interfaces and battery-powered measurement nodes. |
| Crosstalk | −96dB at 1MHz - prevents interference between active and inactive channels in dense analog routing applications. |
| Enable Turn-On Time | 200ns max over temperature - supports high-speed multiplexing in real-time data acquisition up to ~1MHz effective sampling rate. |
| Package | 16-pin QSOP (E16-4), 0.15" wide - provides compact footprint with standard surface-mount assembly compatibility and thermal performance up to +85°C. |
Pinout & Package
MAX4582LEEE is housed in a 16-pin QSOP package (package code E16-4), measuring 4.4mm × 3.9mm × 1.5mm, with gull-wing leads and standard 0.025" pitch. The exposed pad is absent - unlike the TQFN variant - making it suitable for standard reflow profiles without thermal pad soldering requirements.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5 | X0–X3 Analog Inputs | Four independent analog input terminals for first 4:1 multiplexer; bidirectional, rail-to-rail capable. |
| 3 | X Output | Common output bus for first 4:1 multiplexer; connects selected X0–X3 channel when ENABLE = low. |
| 6 | ENABLE | Active-low digital control; drives all switches open (high-impedance) when high; must be tied low or driven for normal operation. |
| 7, 8 | GND | Digital/analog ground reference; no analog signal ground path - analog signals float between VCC and GND. |
| 9, 10 | Y0–Y3 Analog Inputs | Four independent analog inputs for second 4:1 multiplexer; electrically isolated from X-side channels. |
| 11 | Y Output | Common output bus for second 4:1 multiplexer; independently selectable from X output. |
| 12, 13 | A, B Address Inputs | Binary select lines (LSB to MSB) determining which of X0–X3 and Y0–Y3 connects to X and Y outputs. |
| 14, 15 | VCC | Single positive supply for analog and digital circuitry; bypass with 0.1µF ceramic capacitor to GND near pin. |
| 16 | NC | No connect - internally unused; must remain unconnected per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input/output voltages from GND to VCC - eliminates level-shifting in mixed-supply systems. |
| Guaranteed 4Ω on-resistance match | Ensures consistent gain and offset across channels in multi-sensor or multi-channel ADC applications. |
| −96dB crosstalk at 1MHz | Enables simultaneous high-frequency signal routing without inter-channel interference in video or comms ICs. |
| TTL/CMOS-compatible logic thresholds | 0.8V/2.0V thresholds ensure reliable switching with 3.3V microcontrollers without external level shifters. |
| Low 2nA off-leakage at +25°C | Maintains signal integrity in high-Z medical sensors, piezoelectric transducers, or battery-backed memory circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-channel analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4052ACPE+ | Same pinout, but wider supply range (+5V to ±20V); higher on-resistance (100Ω typ at +15V); no guaranteed RON match spec. | Preferred in ±15V op-amp systems; unsuitable for low-voltage (<3.3V) logic control due to higher VIH threshold. | Select MAX4052ACPE+ only when bipolar supplies or higher voltage headroom are required; not drop-in for +3.3V logic environments. |
| ADG708BRUZ | 8-channel single mux (not dual 4:1); 4.5Ω on-resistance at +5V; 16-TSSOP package; lacks ENABLE pin - uses EN bar instead. | Better suited for sequential 8:1 scanning than parallel dual-path routing; requires PCB redesign for pin compatibility. | Choose ADG708BRUZ when consolidating channels onto one bus; avoid if dual independent outputs (X/Y) are mandatory. |
Compared with MAX4582LEEE, MAX4052ACPE+ supports wider supply rails but sacrifices on-resistance matching and low-voltage logic compatibility, while ADG708BRUZ offers lower on-resistance at 5V but abandons the dual-output architecture essential for parallel signal routing.

FAQ
What is the maximum supply voltage rating for MAX4582LEEE?
The MAX4582LEEE has an absolute maximum supply voltage of +13V, but its specified operational range is +2V to +12V. Operation at +12.6V is permitted per Electrical Characteristics testing conditions, and exceeding +13V risks permanent damage due to internal ESD diode breakdown. Always observe the 0.3V clamp limit relative to GND on any pin.
Does MAX4582LEEE support bidirectional analog signal flow?
Yes, MAX4582LEEE supports fully bidirectional analog signal flow - its CMOS transmission-gate architecture makes input and output pins functionally interchangeable. Signals pass equally well from X0 to X or from X to X0, enabling flexible routing in both source-driven and load-driven configurations without polarity constraints.
Is the ENABLE pin on MAX4582LEEE active-high or active-low?
The ENABLE pin on MAX4582LEEE is active-low: when pulled low, the selected analog channels conduct; when driven high, all switches enter high-impedance off-state. The datasheet specifies VENABLE_L ≤ 0.8V for guaranteed turn-on and VENABLE_H ≥ 1.5V for guaranteed turn-off across temperature.
What is the thermal performance of the MAX4582LEEE QSOP package?
The MAX4582LEEE in 16-pin QSOP has a thermal resistance θJA of 120°C/W and a continuous power dissipation limit of 667mW at +70°C ambient, derating by 8.3mW/°C above that. Its maximum junction temperature is +150°C, and it operates reliably from −40°C to +85°C ambient without forced airflow.
Can MAX4582LEEE replace industry-standard 74HC4052 in existing designs?
Yes, MAX4582LEEE is pin-compatible with 74HC4052 in QSOP-16 and shares identical pin functions (X0–X3, Y0–Y3, X, Y, A, B, ENABLE, VCC, GND), but offers superior analog performance: lower on-resistance (80Ω vs. ~120Ω), tighter RON matching (4Ω vs. unspecified), and guaranteed −96dB crosstalk versus typical −60dB for HC devices.
