Product details
Overview
MAX4782ETE+ from Maxim Integrated is a high-speed, low-voltage dual 4-channel CMOS analog multiplexer configured for bidirectional rail-to-rail signal routing. It features 0.7Ω on-resistance at +3V supply, 11ns turn-on time, and operates from +1.6V to +3.6V. Designed for audio signal routing and low-voltage data-acquisition systems, it supports ±150mA continuous channel current with <3µW quiescent power consumption.
For engineers reviewing the MAX4782ETE+ datasheet, MAX4782ETE+ pinout, MAX4782ETE+ application, or MAX4782ETE+ equivalent, key selection criteria include on-resistance matching (0.3Ω), break-before-make timing (2ns), logic-level compatibility (+1.8V CMOS), and thin QFN package thermal performance in space-constrained battery-operated designs.
Technical Context
The MAX4782ETE+ implements two independent 4:1 analog multiplexers sharing common address lines (A, B) and individual enable control per section. Its CMOS switch architecture uses matched P/N transistor pairs to achieve low RON flatness (0.1Ω) and tight channel-to-channel RON matching (0.3Ω) across the full analog signal range (0V to VCC).
Switching is controlled by synchronous digital inputs referenced to VCC, with VIH = 1.4V and VIL = 0.5V at +3V supply. The device integrates ESD protection diodes on all analog I/O pins and exhibits <1µA supply current, enabling ultra-low-power operation in portable instrumentation and sensor interface applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 0.7Ω at +3V supply - enables minimal signal attenuation and voltage drop in precision analog paths |
| On-Resistance Matching | 0.3Ω max between channels - ensures consistent gain/attenuation across multiplexed signal paths |
| Turn-On Time (tON) | 11ns typical - supports high-speed sampling and dynamic signal routing up to ~30MHz |
| Analog Signal Range | Rail-to-rail (0V to VCC) - preserves full dynamic range of baseband audio and sensor signals |
| Supply Voltage Range | +1.6V to +3.6V - compatible with single-cell Li-ion, NiMH, and regulated 1.8V/3.3V system rails |
| Channel Current Rating | ±150mA continuous - handles line-level audio drive and moderate-signal instrumentation loads |
| Quiescent Power | <3µW - eliminates thermal concerns and extends battery life in always-on monitoring circuits |
Pinout & Package
MAX4782ETE+ is housed in a 3mm × 3mm, 16-pin thin QFN package with exposed thermal pad (EP) connected to GND. The package supports fine-pitch PCB assembly and provides low thermal resistance for sustained switching operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 2, 4 (QFN: 15, 3, 16, 2) | Y0–Y3 | Analog inputs for first 4:1 multiplexer section - bidirectional, interchangeable with Y output |
| 3 (QFN: 1) | Y | Common analog output for Y-section - connects selected Y0–Y3 input under AB address control |
| 13 (QFN: 11) | X | Common analog output for X-section - connects selected X0–X3 input under AB address control |
| 12, 14, 15, 11 (QFN: 10, 12, 13, 9) | X0–X3 | Analog inputs for second 4:1 multiplexer section - fully symmetric with Y-section I/O |
| 6 (QFN: 4) | ENABLE | Active-high global disable - sets both multiplexer sections to high-impedance open state when high |
| 7 (QFN: 5) | N.C. | No internal connection - must be left unconnected or tied to GND for mechanical stability |
| 8 (QFN: 6) | GND | System ground reference for analog and digital circuitry - connects to EP for thermal management |
| 9 (QFN: 7) | B | Address bit B - selects channel pair (00=0/1, 01=2/3) in conjunction with A for 4:1 decoding |
| 10 (QFN: 8) | A | Address bit A - least-significant address input determining individual channel within pair |
| 16 (QFN: 14) | VCC | +1.6V to +3.6V analog/digital supply - powers internal CMOS switches and logic; decoupling required |
| EP | Exposed Pad | Thermal and electrical ground - must be soldered to PCB GND plane for rated power dissipation (1349mW) |
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 |
|---|---|---|---|
| MAX4782EUE+ | TSSOP-16 package (4.4mm × 5mm); higher thermal resistance (457mW vs. 1349mW); identical electrical specs | Suitable for prototyping or legacy layouts where QFN assembly is unavailable; less optimal for high-density or thermally constrained boards | Select MAX4782EUE+ only when TSSOP footprint compatibility or hand-soldering requirements override thermal/power needs. |
| ADG732BRUZ | 32-channel single-ended mux; 4.5Ω RON at +3V; 12ns tON; 24-TSSOP package; no ENABLE pin per section | Better suited for high-channel-count, lower-speed industrial I/O modules rather than dual-path audio/data routing | Choose ADG732BRUZ only when scaling beyond 8 total channels is required and higher RON is acceptable. |
Compared with MAX4782EUE+, MAX4782ETE+ delivers 2.9× higher power dissipation capability and 30% smaller board area; versus ADG732BRUZ, it offers 6.4× lower on-resistance and dedicated dual-section enable control for independent signal path management.

FAQ
What is the maximum analog signal voltage range supported by the MAX4782ETE+?
The MAX4782ETE+ supports rail-to-rail analog signals from 0V to VCC. When powered from a +3.3V supply, this means signals from 0V to +3.3V are fully passed without clipping. Exceeding VCC or going below GND forward-biases internal ESD diodes and must be avoided unless external clamping is implemented. This range is confirmed in the Electrical Characteristics table under "Analog Signal Range" for both +3V and +1.8V supplies.
Can the MAX4782ETE+ operate from a +1.8V supply, and how does performance change?
Yes, the MAX4782ETE+ operates from +1.6V to +3.6V. At +1.8V supply, on-resistance increases to 1.6Ω (typical), on-resistance matching degrades to 0.3Ω (typical), and switching times increase to 17ns tON/8ns tOFF. These values are specified in the +1.8V Electrical Characteristics table and reflect the inherent trade-off between supply voltage and CMOS switch conduction efficiency.
Is the MAX4782ETE+ pin-compatible with standard industry devices?
Yes, the MAX4782ETE+ is pin-compatible with the industry-standard 74HC4052 and MAX4618 in both TSSOP and thin QFN packages. Pin functions (X, Y, X0–X3, Y0–Y3, A, B, ENABLE, GND, VCC) align directly, enabling drop-in replacement in existing designs - provided layout accommodates the 3mm × 3mm QFN footprint and thermal pad connection.
What is the purpose of the N.C. pin on the MAX4782ETE+?
Pin 7 (TSSOP) / Pin 5 (thin QFN) is designated N.C. (No Connection) and is not internally bonded. It must remain unconnected in the PCB layout. While some designs tie it to GND for mechanical stability or thermal relief, Maxim's datasheet explicitly states it is not internally connected and carries no electrical function in the MAX4782ETE+.
How does the ENABLE pin function in the MAX4782ETE+?
The ENABLE pin (Pin 6 / QFN Pin 4) is an active-high digital input that globally disables both 4:1 multiplexer sections. When driven high, all analog switches open simultaneously, presenting high-impedance (>1GΩ) between all X/Y inputs and outputs. When low (or grounded), the multiplexers respond to address inputs A and B. This behavior is verified in Table 1 (Truth Table) and the Pin Description section of the datasheet.
