Product details
Overview
MAX4780EUE+ from Maxim Integrated is a low-voltage, quad 2:1 analog multiplexer IC operating from a single +1.6V to +4.2V supply, featuring 0.7Ω on-resistance at +2.7V, 20ns turn-on time, and rail-to-rail signal handling. It serves as a high-speed analog signal routing switch in portable audio subsystems, battery-powered data acquisition, and cellular phone baseband signal paths.
For engineers reviewing the MAX4780EUE+ datasheet, MAX4780EUE+ pinout, MAX4780EUE+ application, or MAX4780EUE+ equivalent, this page delivers verified electrical parameters, TSSOP-16 pin mapping, real-world use scenarios, and two validated alternative parts for low-voltage analog switching designs.
Technical Context
The MAX4780EUE+ implements four independent bidirectional 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 a single address input (A0) and an enable (EN) pin to select between NO/NC paths per channel.
It supports rail-to-rail analog signals from GND to V+, maintains <0.1Ω RON flatness at +2.7V, and guarantees break-before-make timing of ≤1ns to prevent signal shorting during switching transitions - critical for audio and sensor signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.6V to +4.2V - enables direct integration into Li-ion battery-powered 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 drivers). |
| RON Flatness | 0.1Ω at +2.7V - ensures consistent gain and linearity across full signal swing (GND to V+). |
| Turn-On / Turn-Off Time | 20ns / 8ns - supports >10MHz analog switching in high-speed data acquisition and communications circuits. |
| Off-Isolation | –67dB at 1MHz - suppresses crosstalk between active and inactive channels in multi-signal routing. |
| Logic Compatibility | +1.8V CMOS-compatible inputs - allows direct interfacing with low-voltage microcontrollers and baseband processors. |
| Quiescent Supply Current | <2µA - preserves battery life in always-on or standby-mode portable devices. |
Pinout & Package
MAX4780EUE+ is housed in a 16-pin TSSOP package (JEDEC MO-153, package code U16+2), with exposed pad not present (unlike QFN variants). Pin 8 is GND; Pin 16 is V+; Pin 15 is A0; Pin 13 is EN; pins 1–7, 9–12, and 14 are analog terminals (COM/NO/NC) arranged per channel.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A0 | Address input controlling NO/NC selection per channel; logic-high selects NO, logic-low selects NC. |
| 2 | NC1 | Normally closed terminal for Channel 1 - connects to COM1 when A0 = low. |
| 3 | NO1 | Normally open terminal for Channel 1 - connects to COM1 when A0 = high. |
| 4 | COM1 | Common analog I/O node for Channel 1 - bidirectional path shared between NC1 and NO1. |
| 5 | NC2 | Normally closed terminal for Channel 2 - connects to COM2 when A0 = low. |
| 6 | NO2 | Normally open terminal for Channel 2 - connects to COM2 when A0 = high. |
| 7 | COM2 | Common analog I/O node for Channel 2 - bidirectional path shared between NC2 and NO2. |
| 8 | GND | Ground reference for analog and digital circuitry - must be low-impedance for noise immunity. |
| 9 | COM3 | Common analog I/O node for Channel 3 - bidirectional path shared between NC3 and NO3. |
| 10 | NO3 | Normally open terminal for Channel 3 - connects to COM3 when A0 = high. |
| 11 | NC3 | Normally closed terminal for Channel 3 - connects to COM3 when A0 = low. |
| 12 | COM4 | Common analog I/O node for Channel 4 - bidirectional path shared between NC4 and NO4. |
| 13 | NO4 | Normally open terminal for Channel 4 - connects to COM4 when A0 = high. |
| 14 | NC4 | Normally closed terminal for Channel 4 - connects to COM4 when A0 = low. |
| 15 | EN | Enable input - logic-low enables all switches; logic-high places all COM outputs in high-impedance state. |
| 16 | V+ | Positive supply input - powers analog switches and internal logic; bypass capacitor required at pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input/output signals from GND to V+ without clipping - essential for full-scale audio and sensor interfaces. |
| 0.1Ω RON flatness | Maintains constant gain and minimal THD (<0.008%) across entire signal range - improves fidelity in audio routing. |
| +1.8V CMOS logic compatibility | Accepts standard low-voltage logic levels even at V+ = +1.8V - eliminates need for external level shifters. |
| Break-before-make timing ≤1ns | Prevents momentary short-circuit between NO and NC paths - avoids signal glitches in precision analog systems. |
| Ultra-low quiescent current (<2µA) | Reduces system standby power - critical for battery longevity in handheld and IoT edge devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2:1 analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4784EUE+ | Replaces EN pin with second address input (A1); adds dual-channel addressing capability. | Required when independent control of two switch pairs is needed (e.g., stereo audio left/right routing). | Select MAX4784EUE+ only if A1-controlled channel grouping is necessary; MAX4780EUE+ suffices for uniform 4-channel selection. |
| TMUX1574PWR | Higher RON (1.5Ω @ 3V), wider supply (1.08V–4.5V), no EN pin, same TSSOP-16 footprint. | Suitable for cost-sensitive, lower-performance applications where 0.7Ω RON is not mandatory. | Choose TMUX1574PWR for simplified control (no EN needed) and broader voltage tolerance, but expect higher conduction loss. |
Compared with MAX4784EUE+, MAX4780EUE+ offers simpler single-bit addressing and integrated enable functionality; compared with TMUX1574PWR, it delivers superior on-resistance and tighter RON flatness for precision analog routing - making it optimal for battery-constrained, high-fidelity signal paths.

FAQ
What is the maximum analog signal voltage range supported by the MAX4780EUE+?
The MAX4780EUE+ supports rail-to-rail analog signals from GND to V+, meaning the full range equals the applied supply voltage. With V+ = +3.0V, signals from 0V to +3.0V pass through with minimal distortion; at V+ = +1.8V, the range is 0V to +1.8V. This capability is confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables of the datasheet, and applies directly to the MAX4780EUE+ TSSOP variant.
Does the MAX4780EUE+ require external pull-up or pull-down resistors on its A0 or EN pins?
No, the MAX4780EUE+ does not require external biasing on A0 or EN. Its logic inputs are CMOS-compatible with defined VIH (+1.4V min at +2.7V supply) and VIL (+0.5V max), and input leakage is specified at ±1µA. Driving A0 and EN directly from microcontroller GPIOs - including rail-to-rail swings - is fully supported and recommended to minimize power consumption, as stated in the Applications Information section.
Can the MAX4780EUE+ be used with a +1.8V supply while driving +3.3V logic signals on A0 and EN?
Yes. The MAX4780EUE+ logic inputs tolerate voltages up to +4.2V regardless of V+ supply level. When V+ = +1.8V, A0 and EN may be driven from +3.3V logic sources without damage or level-shifting - a key feature explicitly documented in the "Logic Inputs" section and Absolute Maximum Ratings table for the MAX4780EUE+.
What is the thermal performance difference between the MAX4780EUE+ (TSSOP) and MAX4780ETE+ (QFN)?
The MAX4780EUE+ in TSSOP has a thermal resistance θJA of 134°C/W (calculated from 755mW max power at +70°C with 9.4mW/°C derating), while the QFN variant (MAX4780ETE+) achieves 85°C/W (1176.5mW / 14.7mW/°C). This means the TSSOP package runs ~50°C hotter under identical load - important for high-current or high-ambient applications. The exposed pad in QFN is absent in MAX4780EUE+.
Is the MAX4780EUE+ pin-compatible with the MAX4784EUE+?
No. While both are 16-pin TSSOP devices, MAX4780EUE+ uses Pin 15 as A0 and Pin 13 as EN, whereas MAX4784EUE+ uses Pin 15 as A1 and Pin 13 as A0 - swapping control pin assignments. The analog pinouts (COM/NO/NC) are identical, but logic pin mapping differs. Therefore, PCB layout is not interchangeable without redesign.
