Product details
Overview
MAX4784EUE+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 from GND to V+. It operates from a single +1.6V to +4.2V supply and consumes less than 1µW quiescent power, enabling high-fidelity signal routing in battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4784EUE+T datasheet, MAX4784EUE+T pinout, MAX4784EUE+T application, or MAX4784EUE+T equivalent, this page delivers verified electrical parameters, TSSOP-16 pin mapping, real-world use cases in cellular phones and PCMCIA cards, and two validated alternative parts with functional and layout-aware selection guidance.
Technical Context
The MAX4784EUE+T implements four independent 2:1 analog switches using CMOS switch architecture, each with separate COM, NO, and NC terminals. Its control logic uses dual address inputs (A0, A1) and an active-low enable (EN), supporting discrete channel selection without bus contention.
It features break-before-make switching (tBBM = 1ns), <5pC charge injection, and matched on-resistance flatness of 0.1Ω at +2.7V - critical for precision instrumentation and low-distortion audio routing where signal integrity across voltage swing must remain stable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.6V to +4.2V single supply - enables direct integration into Li-ion and coin-cell powered systems without level-shifting. |
| On-Resistance (RON) | 0.7Ω at +2.7V - supports ≤300mA continuous current per channel with minimal IR drop and thermal rise. |
| RON Flatness | 0.1Ω over full analog range - ensures consistent gain and THD performance across 0–V+ signal swing. |
| Switching Speeds | tON = 20ns, tOFF = 8ns - suitable for high-speed data acquisition and video signal routing up to 123MHz bandwidth. |
| Off-Isolation | −67dB at 1MHz - suppresses crosstalk between active and inactive channels in multi-signal routing applications. |
| Leakage Current | ±5nA max (COM/NO/NC off-state) - preserves accuracy in high-impedance sensor front-ends and battery monitoring circuits. |
| Logic Compatibility | +1.8V CMOS input thresholds - allows direct interfacing with 1.8V/3.3V microcontrollers without external translators. |
Pinout & Package
MAX4784EUE+T is housed in a 16-pin TSSOP package (JEDEC MO-153, 5.0mm × 4.4mm × 1.2mm) with exposed pad not electrically connected; thermal performance optimized via PCB ground plane attachment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | A0 | Address input selecting NO/NC pair for Channels 1–2 (A0=0→CH1/CH2 NC path; A0=1→NO path). |
| 2, 16 | NC1 | Normally closed terminal for Channel 1 - connects to COM1 when A0=0 and EN=low. |
| 3, 1 | NO1 | Normally open terminal for Channel 1 - connects to COM1 only when A0=1 and EN=low. |
| 4, 2 | COM1 | Common analog I/O node for Channel 1 - bidirectional; serves as input or output depending on signal flow. |
| 5, 3 | NC2 | Normally closed terminal for Channel 2 - pairs with COM2 under A0=0 condition. |
| 6, 4 | NO2 | Normally open terminal for Channel 2 - activated when A0=1, enabling signal path to COM2. |
| 7, 5 | COM2 | Common analog I/O node for Channel 2 - shares same switching logic as COM1 but independent path. |
| 8, 6 | GND | Ground reference for analog and digital circuitry - must be low-impedance connection to minimize noise coupling. |
| 9, 7 | COM3 | Common node for Channel 3 - controlled by A1 (pin 15); A1=0 selects NC3, A1=1 selects NO3. |
| 10, 8 | NO3 | Normally open terminal for Channel 3 - connects to COM3 only when A1=1 and EN=low. |
| 11, 9 | NC3 | Normally closed terminal for Channel 3 - default path to COM3 when A1=0. |
| 12, 10 | COM4 | Common node for Channel 4 - completes quad configuration; identical timing and RON behavior as other COM pins. |
| 13, 11 | NO4 | Normally open terminal for Channel 4 - activated by A1=1, enabling fourth independent 2:1 routing path. |
| 14, 12 | NC4 | Normally closed terminal for Channel 4 - provides default connection to COM4 when A1=0. |
| 15, 13 | A1 | Address input controlling Channels 3 and 4 - works in tandem with A0 to configure all four 2:1 switches. |
| 16, 14 | V+ | Positive supply input - powers internal CMOS switches and logic; bypass capacitor (0.1µF to GND) required for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog operation | Supports signals from GND to V+ without clipping - essential for full-scale audio and sensor signal preservation. |
| Break-before-make switching | 1ns guaranteed interval prevents momentary shorting between NC and NO paths - avoids signal glitches in power routing. |
| Ultra-low quiescent power | <1µW shutdown current - extends battery life in always-on portable devices like modems and cellular handsets. |
| Low charge injection (5pC) | Minimizes voltage step errors at COM during switching - critical for precision ADC/DAC interface and sample-hold circuits. |
| High off-isolation (−67dB) | Blocks leakage from active to inactive channels - maintains signal purity in multi-source audio/video routing. |

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 |
|---|---|---|---|
| MAX4780EUE+T | Uses EN pin instead of A1; only two independently controllable 2:1 switches (CH1/CH2), not four. | Limited to dual-channel routing; unsuitable for full quad-path designs requiring A1-addressed CH3/CH4. | Select MAX4784EUE+T when four independent 2:1 paths with dual address control (A0/A1) are required. |
| TMUX1308PWR | 8-channel single-pole multiplexer (not quad 2:1); 0.5Ω RON at 3.3V; supports 5V tolerant logic. | Requires different control scheme (3-bit address bus); lacks NC/NO dual-path topology for fail-safe routing. | Choose TMUX1308PWR only if channel count >4 is needed and NC/NO redundancy is not required. |
Compared with MAX4780EUE+T and TMUX1308PWR, the MAX4784EUE+T uniquely delivers four fully independent 2:1 analog switches with dual address decoding (A0/A1) and true normally-closed/normally-open topology - enabling robust signal path redundancy and flexible routing in space-constrained portable electronics.

FAQ
What is the maximum continuous current rating per channel for the MAX4784EUE+T?
The MAX4784EUE+T supports ±300mA continuous current per channel at TA ≤ +85°C, as specified in Absolute Maximum Ratings. This rating applies to COM_, NO_, and NC_ terminals under steady-state conditions and assumes proper PCB thermal design - especially important when operating near 0.7Ω RON at +2.7V supply where power dissipation reaches ~63mW per channel at full load.
Does the MAX4784EUE+T support rail-to-rail analog signal switching?
Yes, the MAX4784EUE+T supports rail-to-rail analog signal switching from GND to V+, confirmed across its full operating supply range (+1.6V to +4.2V). The CMOS switch architecture ensures minimal on-resistance variation (<0.1Ω flatness) over the entire voltage range, enabling accurate signal transmission without clipping or distortion in audio, sensor, and data-acquisition applications.
How does the enable (EN) pin function on the MAX4784EUE+T?
The EN pin on the MAX4784EUE+T is an active-low enable that places all four analog switches into high-impedance off-state when driven high. When EN is tied to GND (or logic low), the switches respond to A0 and A1 address inputs. This allows system-level power gating - for example, disabling all signal paths during processor sleep mode while maintaining low quiescent current (<1µW).
Can the MAX4784EUE+T operate with a +1.8V supply, and what are the key trade-offs?
Yes, the MAX4784EUE+T operates down to +1.8V supply, with RON increasing to 2Ω (typical) and switching speeds reducing to tON = 25ns/tOFF = 10ns. Logic thresholds adjust to VIH = +1.0V/VIL = +0.4V, maintaining compatibility with 1.8V microcontrollers. The trade-off is higher conduction loss and slightly reduced bandwidth versus +2.7V operation - acceptable in ultra-low-power sensor nodes where efficiency outweighs speed.
Is the exposed pad on the MAX4784EUE+T electrically connected?
No, the exposed pad on the MAX4784EUE+T is not electrically connected - it is internally tied to GND only in the QFN variant (MAX4784ETE). For the TSSOP-packaged MAX4784EUE+T, there is no exposed pad; the "EP" reference in the datasheet applies exclusively to the Thin QFN version. The TSSOP-16 package relies on standard lead-frame thermal conduction through pins 6 (GND) and 14 (V+).
