Product details
Overview
MAX4780EUE+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, consumes <1µW quiescent power, and is used for precision signal routing in battery-powered audio/video systems.
For engineers reviewing the MAX4780EUE+T datasheet, MAX4780EUE+T pinout, MAX4780EUE+T application, or MAX4780EUE+T equivalent, key selection criteria include on-resistance flatness (0.1Ω), break-before-make timing (1ns), CMOS logic compatibility down to +1.8V, and TSSOP-16 package thermal performance in space-constrained portable designs.
Technical Context
The MAX4780EUE+T implements four independent bidirectional 2:1 analog switches using CMOS switch architecture, each with separate normally open (NO_) and normally closed (NC_) terminals controlled by a single A0 address input and global EN enable. Its internal logic ensures break-before-make switching with guaranteed 1ns interval to prevent signal shorting during state transitions.
All channels support rail-to-rail analog signals (GND to V+) and maintain low on-resistance variation (<0.3Ω flatness) across the full signal range at +2.7V. Input logic thresholds scale with supply voltage-VIH = +1.4V min at +2.7V, enabling interoperability with +1.8V CMOS controllers without level shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.6V to +4.2V single supply - enables direct integration with Li-ion battery (3.0–4.2V) and low-power microcontrollers. |
| On-Resistance (RON) | 0.7Ω at +2.7V, 100mA - supports ≤300mA continuous current per channel with <210mV IR drop at full load. |
| RON Flatness | 0.1Ω at +2.7V - ensures consistent gain/attenuation across audio/video signal range (0–2.7V), critical for THD-sensitive paths. |
| Switching Speed | tON = 20ns, tOFF = 8ns - supports >10MHz analog signal routing with minimal propagation delay skew between channels. |
| Off-Isolation | −67dB at 1MHz - suppresses crosstalk between active and inactive channels in multi-source audio routing applications. |
| Logic Compatibility | +1.8V CMOS inputs - interfaces directly with 1.8V FPGA I/O banks and low-voltage microcontrollers without external translators. |
| Quiescent Supply Current | 2µA max - extends battery life in always-on signal-path monitoring circuits (e.g., headset detection). |
Pinout & Package
MAX4780EUE+T is housed in a 16-pin TSSOP package (package code U16+2), with exposed pad omitted (unlike QFN variants). Pin 8 is GND; Pin 16 is V+; Pin 15 is A0 address input; Pin 13 is EN enable (active-low); pins 1–7, 9–12, and 14 are analog terminals (COM1–COM4, NO1–NO4, NC1–NC4) arranged to minimize adjacent-channel coupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 11, 14 | NC1–NC4 | Normally closed analog terminals - connect to default signal path when A0 = 0 and EN = low. |
| 3, 6, 10, 13 | NO1–NO4 | Normally open analog terminals - selected when A0 = 1 and EN = low; isolated when unselected. |
| 4, 7, 9, 12 | COM1–COM4 | Common analog I/O ports - bidirectional; serve as input when routing to NO_/NC_, output when sourcing from NO_/NC_. |
| 15 | A0 | Address select input - controls NO_/NC_ connection per channel (0 = NC_, 1 = NO_); CMOS-compatible threshold. |
| 13 | EN | Active-low enable - drives all COM_ terminals to high-impedance when high; required for power-gating unused paths. |
| 16 | V+ | Positive supply - powers analog switches and logic; must be bypassed with 0.1µF capacitor to GND near pin. |
| 8 | GND | Analog/digital ground reference - shared return for all channels and logic; requires low-impedance PCB plane. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog inputs from GND to V+ without clipping - eliminates need for external biasing in single-supply audio codecs. |
| 0.1Ω RON flatness | Maintains <0.04% gain error across 0–2.7V signal range - preserves linearity in precision sensor multiplexing. |
| 1ns break-before-make | Guarantees no overlap between NC_ and NO_ conduction - prevents momentary shorts in power-routing applications. |
| +1.8V CMOS logic interface | Accepts standard 1.8V logic levels regardless of V+ (up to +4.2V) - simplifies mixed-voltage system integration. |
| 85°C operating range | Rated for industrial temperature operation - suitable for embedded automotive infotainment and portable medical devices. |
Applications
| Audio Signal Routing | Battery-Powered Data Acquisition |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4784EUE+T | Includes A1 address input for independent 2:1 control per pair; lacks EN pin; same RON, speed, and package. | Required when dual independent switching per channel pair is needed (e.g., stereo left/right routing with separate control). | Select MAX4784EUE+T only if A1 functionality is required; MAX4780EUE+T provides simpler single-bit control with global enable. |
| TMUX1574PWR | 4-channel 2:1 mux with 0.5Ω RON at 3.3V, but higher 5µA supply current and no −40°C to +85°C guarantee. | Suitable for cost-sensitive consumer electronics where extended temperature range is not required. | Choose TMUX1574PWR for lower on-resistance in 3.3V systems; MAX4780EUE+T remains preferred for battery life and industrial temp compliance. |
Compared with MAX4784EUE+T, MAX4780EUE+T trades independent channel addressing for global enable control-critical for synchronized power gating. Against TMUX1574PWR, it delivers 2.5× lower quiescent current and guaranteed operation across −40°C to +85°C, making it superior for portable industrial designs.

FAQ
What is the maximum continuous current rating per channel for MAX4780EUE+T?
The MAX4780EUE+T supports ±300mA continuous current per channel at TA ≤ +70°C, as specified in Absolute Maximum Ratings. At full rated load and +2.7V supply, the 0.7Ω on-resistance results in ≤210mV voltage drop and 44mW power dissipation per channel-well within thermal limits of the TSSOP package.
Does MAX4780EUE+T support rail-to-rail analog signals when powered from +1.8V?
Yes, MAX4780EUE+T supports rail-to-rail analog signals (GND to V+) at +1.8V supply, as confirmed in the Electrical Characteristics table. However, on-resistance increases to 2Ω at +1.8V, and logic inputs require VIH ≥ +1.0V-still compatible with standard +1.8V CMOS drivers.
Can MAX4780EUE+T be used in audio applications requiring low total harmonic distortion?
Yes, MAX4780EUE+T achieves 0.008% THD at 20Hz–20kHz with 2VP-P signal and 32Ω load at +3.0V supply-meeting requirements for high-fidelity portable audio. Its 0.1Ω RON flatness and low charge injection (5pC) preserve signal integrity across the audible band.
What is the function of the EN pin on MAX4780EUE+T, and how should it be connected?
The EN pin on MAX4780EUE+T is an active-low enable that places all COM_ terminals in high-impedance state when driven high. For normal operation, EN must be tied to GND. Leaving EN floating is not permitted-internal leakage could cause unpredictable channel states and increased supply current.
How does the pinout of MAX4780EUE+T differ from MAX4784EUE+T in the same TSSOP package?
In the TSSOP package, MAX4780EUE+T uses Pin 13 as EN and omits A1, whereas MAX4784EUE+T uses Pin 13 as A1 and replaces EN with A1 functionality. Both share identical COM_/NO_/NC_ pin assignments (Pins 1–12, 14–16), but control logic differs: MAX4780EUE+T uses A0 + EN; MAX4784EUE+T uses A0 + A1 for independent pair control.
