Product details
Overview
MAX4784ETE+T from Maxim Integrated is a low-voltage, quad 2:1 analog multiplexer IC with 0.7Ω on-resistance at +2.7V supply, 20ns turn-on time, and rail-to-rail signal handling (0V to V+), designed for power routing and audio/video signal switching in battery-powered portable electronics.
For engineers reviewing the MAX4784ETE+T datasheet, MAX4784ETE+T pinout, MAX4784ETE+T application, or MAX4784ETE+T equivalent, this page delivers verified electrical parameters, QFN-EP package details, truth-table–validated switching logic, and real-world selection guidance for low-power analog signal path design.
Technical Context
The MAX4784ETE+T implements four independent 2:1 analog switches using CMOS process technology, each with separate normally open (NO) and normally closed (NC) terminals plus a common (COM) terminal. Its control logic uses dual address inputs (A0, A1) and an active-low enable (EN) to select one of two analog paths per channel.
It operates from a single +1.6V to +4.2V supply, supports +1.8V CMOS-compatible logic thresholds, and guarantees break-before-make timing (1ns) to prevent signal shorting during state transitions - critical for audio and data-acquisition integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.6V to +4.2V - enables direct integration into Li-ion and single-cell battery systems without level-shifting. |
| On-Resistance (RON) | 0.7Ω at +2.7V - minimizes voltage drop and power loss in high-current analog paths (e.g., speaker routing). |
| RON Flatness | 0.1Ω at +2.7V - ensures consistent gain and linearity across full analog input range (0V to V+). |
| Switching Speed | tON = 20ns, tOFF = 8ns - supports fast channel reconfiguration in multi-source audio or sensor-mux applications. |
| Off-Isolation | –67dB at 1MHz - suppresses crosstalk between active and inactive channels in dense PCB layouts. |
| Leakage Current | ±5nA (NO_/NC_ off-leakage, +85°C) - preserves signal integrity in high-impedance sensor front-ends. |
| Package | 16-pin 3mm × 3mm Thin QFN-EP - provides compact footprint and enhanced thermal dissipation via exposed pad. |
Pinout & Package
MAX4784ETE+T is housed in a 16-pin 3mm × 3mm Thin QFN package with exposed pad (EP), internally connected to GND for thermal management. The EP must be soldered to a large ground plane to ensure reliable operation at rated current.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A0) | Address Input | Selects NO/NC path per switch pair; logic-compatible with +1.8V CMOS levels regardless of V+. |
| 2 (NC1) | Normally Closed Terminal | Connected to COM1 when A0/A1 = 0; maintains default signal path during power-up or EN deassertion. |
| 3 (NO1) | Normally Open Terminal | Connected to COM1 only when A0/A1 = 1; used for alternate signal routing or redundancy. |
| 4 (COM1) | Analog Switch Common Terminal | Bidirectional I/O node - accepts or delivers analog signals up to rail-to-rail (0V to V+). |
| 13 (EN) | Enable Input | Active-low control: pull low to activate all four switches; drive high to place all COM outputs in high-Z state. |
| 14 (V+) | Positive Supply Voltage | Single power rail for analog and digital sections; sequencing requires V+ applied before analog signals. |
| 8 (GND) | Ground Reference | Common return for analog signals, logic inputs, and internal bias; tied to EP for thermal conduction. |
| EP | Exposed Pad | Internally connected to GND; not electrically functional as signal terminal - mandatory thermal connection. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports 0V to V+ input/output swing without clipping - essential for full-scale audio and sensor signals. |
| +1.8V CMOS logic compatibility | Accepts VIH ≥ 1.0V and VIL ≤ 0.4V at +1.8V supply - simplifies interface with low-voltage microcontrollers. |
| Break-before-make switching | Guaranteed 1ns minimum dead time prevents momentary shorting between NC and NO paths - avoids signal corruption. |
| Ultra-low quiescent power | < 2µA supply current - extends battery life in always-on portable devices such as modems and cellular handsets. |
| Low charge injection (5pC) | Minimizes voltage glitch on COM node during switching - critical for precision ADC front-end multiplexing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2:1 analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4780ETE+T | Uses A0/A1 address inputs only; no EN pin - lacks global disable function. | Suitable where per-channel addressing suffices and global shutdown is unnecessary. | Choose MAX4780ETE+T if board layout omits enable control and all switches operate synchronously. |
| TMUX1574RTER | Higher RON (1.9Ω at +3.3V), wider supply (1.08V–5.5V), no NC terminals - single-pole double-throw only. | Designed for general-purpose muxing without fail-safe NC path requirement. | Prefer TMUX1574RTER when NC functionality is unused and broader voltage support outweighs RON penalty. |
Compared with MAX4780ETE+T, MAX4784ETE+T adds EN for system-level power gating; compared with TMUX1574RTER, it offers lower RON, NC terminals for default-path reliability, and guaranteed break-before-make - making it optimal for audio and battery-critical designs.

FAQ
What is the maximum continuous current rating for MAX4784ETE+T?
The MAX4784ETE+T supports ±300mA continuous current per COM/NO/NC terminal. This rating applies across the full operating temperature range (–40°C to +85°C) and ensures reliable conduction in power-routing and speaker-drive applications without thermal derating under typical PCB copper area conditions.
Does MAX4784ETE+T support rail-to-rail analog signal switching?
Yes, MAX4784ETE+T supports rail-to-rail analog signal switching from 0V to V+ (up to +4.2V). Its CMOS switch architecture allows bidirectional signal flow with minimal distortion - confirmed by THD of 0.008% at 2VP-P and –95dB crosstalk at 1MHz - making it suitable for high-fidelity audio and precision sensor interfaces.
How does the EN pin function on MAX4784ETE+T?
The EN pin on MAX4784ETE+T is an active-low enable input. When pulled low, all four analog switches operate according to A0/A1 logic states; when driven high, all COM outputs enter high-impedance state - effectively disconnecting all signal paths. This feature enables system-level power gating and reduces standby leakage in battery-critical designs.
What is the purpose of the exposed pad (EP) on MAX4784ETE+T?
The exposed pad (EP) on MAX4784ETE+T is internally connected to GND and serves exclusively for thermal conduction. It must be soldered to a large PCB ground plane to dissipate heat and maintain junction temperature within safe limits (max +150°C). EP is not intended as an electrical signal terminal and must not be left floating or connected to any voltage other than GND.
Can MAX4784ETE+T operate with a +1.8V supply?
Yes, MAX4784ETE+T operates down to +1.6V and is fully specified at +1.8V. At this supply, it delivers 2Ω on-resistance, +1.0V logic-high threshold, and 30ns turn-on time - enabling compatibility with ultra-low-power microcontrollers and single-cell Li-ion systems while maintaining functional integrity across –40°C to +85°C.
