Product details
Overview
MAX4782ETE+T from Maxim Integrated is a high-speed, low-voltage dual 4-channel analog multiplexer configured for bidirectional rail-to-rail signal routing. It features 0.7Ω on-resistance at +3V supply, 11ns turn-on time, ±150mA continuous current handling, and operates from +1.6V to +3.6V. It is used in audio signal routing and low-voltage data-acquisition systems where low distortion and fast switching are critical.
For engineers reviewing the MAX4782ETE+T datasheet, MAX4782ETE+T pinout, MAX4782ETE+T application, or MAX4782ETE+T equivalent, this page delivers verified specifications, validated pin functions, confirmed package mapping (16-pin 3mm × 3mm thin QFN), and two rigorously cross-checked alternative parts for dual 4:1 analog mux selection.
Technical Context
The MAX4782ETE+T implements two independent 4:1 analog multiplexers with shared digital address inputs (A, B) and individual enable control per section. Each mux supports bidirectional signal flow with CMOS-compatible logic thresholds (VIH = 1.4V, VIL = 0.5V at +3V).
It uses a single-supply architecture with internal ESD diodes clamping analog pins to VCC and GND. On-resistance flatness is 0.1Ω and channel-to-channel RON match is 0.3Ω at +3V, enabling precision signal routing without gain error across channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 0.7Ω at +3V supply - ensures minimal voltage drop and signal attenuation in precision analog paths |
| Turn-On Time | 11ns typical - enables high-speed sampling and dynamic signal reconfiguration |
| Analog Signal Range | Rail-to-rail (0V to VCC) - supports full-scale input/output swing without clipping |
| Supply Voltage Range | +1.6V to +3.6V - compatible with modern low-power microcontrollers and battery-operated systems |
| Channel Current Rating | ±150mA continuous - handles line-level audio, sensor outputs, and DAC/ADC interface currents |
| Off-Isolation | −90dB at 1MHz - suppresses crosstalk between inactive and active channels in dense routing |
| Charge Injection | −110pC - limits voltage glitch on sampled-hold nodes in data-acquisition front-ends |
Pinout & Package
MAX4782ETE+T is housed in a 16-pin 3mm × 3mm thin QFN package with exposed thermal pad (EP) tied to GND. The package supports high-density PCB layouts and efficient heat dissipation in space-constrained applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 2, 4 (QFN: 15, 3, 16, 2) |
Y0–Y3 | Analog inputs to second 4:1 mux - interchangeable as source or sink in bidirectional operation |
| 3 (QFN: 1) |
Y | Common output of second 4:1 mux - connects selected Y0–Y3 channel to system load |
| 6 (QFN: 4) |
ENABLE | Digital enable input - logic high disables both mux sections; default low enables normal operation |
| 7 (QFN: 5) |
N.C. | No internal connection - must be left floating or grounded; no electrical function |
| 8 (QFN: 6) |
GND | Ground reference for analog and digital circuitry - requires low-impedance connection to system ground plane |
| 9 (QFN: 7) |
B | Address bit B - selects one of four Y inputs in conjunction with A (binary encoding) |
| 10 (QFN: 8) |
A | Address bit A - least-significant address input for Y-channel selection |
| 12, 14, 15, 11 (QFN: 10, 12, 13, 9) |
X0–X3 | Analog inputs to first 4:1 mux - electrically identical to Y0–Y3, supporting dual independent routing paths |
| 13 (QFN: 11) |
X | Common output of first 4:1 mux - routes selected X0–X3 to separate signal path |
| 16 (QFN: 14) |
VCC | +1.6V to +3.6V supply - powers analog switches and digital control logic; bypass capacitor required |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance flatness | 0.1Ω over full analog range - maintains consistent gain and linearity regardless of signal voltage |
| Break-before-make timing | 2ns typical - prevents momentary shorting between channels during address transitions |
| +1.8V CMOS logic compatibility | VIH = 1.4V, VIL = 0.5V at +3V - interfaces directly with 1.8V/3.3V microcontrollers without level shifters |
| Ultra-low quiescent power | <3µW - enables always-on signal routing in battery-powered portable equipment |
| Pin compatibility | Matches industry-standard 74HC4052 footprint - allows drop-in replacement in existing designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4:1 analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4782EUE+ | TSSOP-16 package (4.4mm × 5mm); same electrical specs and pinout as MAX4782ETE+T | Suitable for through-hole prototyping or legacy PCBs with TSSOP footprints; higher thermal resistance than QFN | Select when board layout accommodates larger footprint or requires hand-soldering compatibility |
| ADG732BRUZ | 32-channel single-ended mux (not dual 4:1); 3.5Ω RON at +3V; 16-bit SPI interface instead of parallel address lines | Used in high-channel-count industrial PLC I/O modules where serial control simplifies wiring and reduces GPIO count | Select only when system requires >8 channels and SPI configurability outweighs need for parallel-address speed and low RON |
Compared with MAX4782EUE+, the MAX4782ETE+T offers superior thermal performance and 38% smaller PCB area; compared with ADG732BRUZ, it delivers 5× lower on-resistance and 3× faster switching but lacks serial programmability and channel count scalability.

FAQ
What is the maximum analog signal voltage range supported by the MAX4782ETE+T?
The MAX4782ETE+T 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 or distortion. This capability is maintained across the full operating temperature range (−40°C to +85°C) and is critical for preserving dynamic range in audio and sensor interfaces. The internal CMOS switch architecture and ESD protection diodes are designed to handle this full range safely.
Can the MAX4782ETE+T operate from a +1.8V supply, and how does performance change?
Yes, the MAX4782ETE+T operates from +1.6V to +3.6V, including +1.8V. At +1.8V, on-resistance increases to 1.6Ω (typical), turn-on time extends to 17ns (typical), and logic thresholds adjust to VIH = 1.0V and VIL = 0.4V. These shifts are fully characterized in the datasheet's +1.8V electrical characteristics table. System designers must verify that the higher RON and slower timing meet signal integrity requirements for their specific use case.
Is the MAX4782ETE+T pin-compatible with the 74HC4052, and what does that mean for design reuse?
Yes, the MAX4782ETE+T is pin-compatible with the 74HC4052 in both TSSOP and thin QFN packages. This means identical PCB footprints and interconnects can be used - allowing direct substitution without layout changes. Functionally, both provide dual 4:1 analog multiplexing with shared A/B address lines and independent enable control. However, the MAX4782ETE+T offers significantly lower on-resistance (0.7Ω vs. ~80Ω), faster switching (11ns vs. ~75ns), and single-supply operation down to +1.6V.
How is the exposed pad (EP) on the MAX4782ETE+T thin QFN package intended to be connected?
The exposed pad (EP) on the MAX4782ETE+T thin QFN package must be soldered to a solid GND plane on the PCB. It is internally connected to the die substrate and serves as the primary thermal and electrical ground path. Leaving it unconnected or floating degrades thermal performance and may cause instability or increased noise. A recommended layout uses ≥4 thermal vias (0.3mm diameter) connecting EP directly to an inner-layer ground plane to ensure optimal junction-to-board thermal resistance.
Does the MAX4782ETE+T support bidirectional signal flow, and how is that implemented?
Yes, the MAX4782ETE+T supports fully bidirectional analog signal flow - meaning any X or Y pin can serve as input or output depending on system topology. This is inherent to its CMOS transmission-gate architecture, where the analog switch channel has no intrinsic directionality. The datasheet explicitly states "input and output pins are identical and interchangeable" and confirms signals pass equally well in either direction. This enables flexible routing in both source-driven and load-driven configurations.
