Product details
Overview
MAX4886ETO+ from Maxim Integrated is a quad high-speed HDMI/DVI 2:1 analog video switch with nFET architecture and internal charge pump, designed for routing RGB/CLK differential signals in digital video interfaces. It delivers 8Ω typical on-resistance, 2.5pF typical on-capacitance, 2.6GHz bandwidth, 0.6dB insertion loss, and operates from +3.0V to +3.6V over –40°C to +85°C in a 42-pin TQFN-EP package.
For engineers reviewing the MAX4886ETO+ datasheet, MAX4886ETO+ pinout, MAX4886ETO+ application, or MAX4886ETO+ equivalent, this device is selected for high-fidelity HDMI/DVI signal routing where low skew (20ps typ), ultra-low crosstalk (–49dB), and return-loss-critical impedance matching are required in notebook docking, HDTV switching, and multimedia A/V systems.
Technical Context
The MAX4886ETO+ implements four independent bidirectional differential switches, each configurable as 2:1 or 1:2 via a single SEL logic input per switch group. Its nFET-based architecture with integrated charge pump enables gate overdrive without external bias, sustaining low RON flatness (<1Ω) across 0–1.5V COM voltage range and <0.8Ω matching between channels.
It supports full-swing analog signaling (0V to VDD) with matched 50Ω trace interface capability, specified for RS = RL = 50Ω conditions. AC performance includes –58dB off-isolation at 50MHz and 2.6GHz –3dB bandwidth, validated under HDMI-compliant PRBS eye-diagram testing at 2.6GHz with 606ps UI.
Key Specifications

|---|---|
| Supply Voltage | +3.0V to +3.6V - compatible with standard 3.3V system rails; no level-shifting required |
| On-Resistance (RON) | 8Ω (typ) - ensures minimal voltage drop and signal attenuation for 50Ω HDMI/DVI TMDS lines |
| On-Capacitance (CON) | 2.5pF (typ) - preserves high-frequency integrity and return loss up to 2.6GHz |
| Bandwidth | 2.6GHz (typ) - supports HDMI 1.3/1.4 pixel clocks and DVI dual-link timing |
| Insertion Loss | 0.6dB (typ) at 50MHz - maintains signal amplitude fidelity across baseband and clock harmonics |
| Propagation Delay | 100ps (typ) - enables sub-nanosecond timing alignment critical for multi-lane video sync |
| Supply Current | 700µA (typ) - suitable for battery-powered notebook and portable docking applications |
Pinout & Package
MAX4886ETO+ is housed in a 42-pin Thin QFN with Exposed Paddle (TQFN-EP), measuring 3.5mm × 9.0mm. The exposed paddle (EP) must be soldered to a solid ground plane for thermal dissipation and signal integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1,4,10,14,17,19,21,39,41) | Ground reference | Multiple distributed GND pins minimize ground bounce and ensure stable return path for all 4 differential pairs |
| VDD (Pins 5,8,13,18,20,30,40,42) | Power supply input | Eight VDD pins enable low-impedance power delivery; requires local 0.1µF ceramic bypassing per VDD group |
| COM1± to COM4± (Pins 2,3,6,7,11,12,15,16) | Common port (bidirectional) | Four differential COM inputs/outputs-connect to source (e.g., HDMI TX) or sink (e.g., monitor input) depending on SEL state |
| NO1± to NO4± (Pins 33,34,31,32,25,24,23,22) | Normally-open port | Active when SEL = 1; routes COM_ to NO_ for 1:2 or 2:1 switching without signal inversion |
| NC1± to NC4± (Pins 38,37,36,35,28,27,26,29) | Normally-closed port | Active when SEL = 0; provides alternate path for seamless failover or dual-source selection |
| SEL (Pin 9) | Switch control input | Single logic input controlling all four switch banks simultaneously; TTL-compatible with 100mV hysteresis |
Key Features
| Feature | Design Value |
|---|---|
| nFET architecture with internal charge pump | Enables rail-to-rail analog switching without external gate drive, reducing BOM count and layout complexity |
| 20ps typical output skew between ports | Maintains inter-pair timing alignment essential for HDMI/DVI pixel clock and data lane synchronization |
| –49dB crosstalk at 50MHz | Prevents interference between adjacent RGB/CLK differential pairs, preserving color fidelity and jitter margin |
| Bidirectional signal routing | Supports both 2:1 mux (dual sources → single display) and 1:2 demux (single source → dual displays) without redesign |
| Exposed paddle (EP) thermal pad | Provides low-thermal-resistance path to PCB ground plane, enabling operation at full bandwidth under sustained load |
Applications
| HDMI/DVI Source Switching | Notebook Docking Station Routing |
|---|---|
Use Scenario: Selecting between two HDMI sources (e.g., Blu-ray player and game console) to feed a single HDTV receiver. IC Role / Device Role / Timing Role: Quad 2:1 analog switch managing four TMDS differential pairs (R/G/B/CLK) with sub-100ps propagation delay.

IC Role / Device Role / Timing Role: Low-capacitance (2.5pF) analog switch preserving LVDS common-mode voltage stability and edge rate integrity. Use Value: Supports >600Mbps LVDS data rates without equalization, extending reach and simplifying timing closure in multi-display systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed video switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4887ETO+ | Same pinout, identical electrical specs, but supports independent SEL control per switch bank (4x SEL inputs vs. 1x shared SEL) | Required for asynchronous switching of individual video lanes (e.g., dynamic CLK/data lane reassignment) | Select MAX4887ETO+ only if per-lane control is needed; otherwise MAX4886ETO+ reduces GPIO count and firmware complexity |
| TS3DV642RGZR | 64-channel 2:1 mux, 3.3V-only, 6Ω RON, 3.5GHz bandwidth, but larger 64-pin VQFN package and higher IDD (1.8mA) | Targeted at high-port-count AV matrix switchers rather than compact 4-lane HDMI routing | Choose TS3DV642RGZR for scalable multi-input systems; MAX4886ETO+ remains optimal for cost- and size-sensitive 2-source HDMI endpoints |
Compared with MAX4887ETO+ and TS3DV642RGZR, the MAX4886ETO+ offers the smallest footprint (3.5mm × 9.0mm), lowest quiescent current (700µA), and simplest control (single SEL), making it ideal for fixed-configuration HDMI/DVI endpoint switching where lane independence and ultra-high channel count are unnecessary.

FAQ
What is the operating temperature range of the MAX4886ETO+?
The MAX4886ETO+ is rated for continuous operation from –40°C to +85°C. This extended temperature range enables reliable deployment in consumer HDTVs, industrial monitors, and automotive infotainment head units where ambient thermal conditions vary significantly. All key specifications-including RON, CON, and bandwidth-are guaranteed across this full range, not just at +25°C.
Does the MAX4886ETO+ require external components for basic operation?
Yes-the MAX4886ETO+ requires at least one 0.1µF ceramic capacitor placed between each VDD pin and nearest GND pin, as specified in the datasheet. Multiple VDD pins demand localized bypassing; a second 1nF–10nF capacitor per VDD group is recommended for high-frequency noise suppression. No external charge pump or level shifters are needed due to its integrated gate-drive architecture.
Can the MAX4886ETO+ be used for LVDS signal switching?
Yes-the MAX4886ETO+ is explicitly cited in its datasheet for LVDS switching applications. Its 2.5pF CON, 8Ω RON, and 2.6GHz bandwidth preserve LVDS common-mode voltage and differential swing integrity. It supports bidirectional LVDS routing without polarity inversion, and its –49dB crosstalk prevents inter-pair interference in multi-channel LVDS displays.
How does the SEL pin control switching behavior in the MAX4886ETO+?
The SEL pin is a single logic input that globally controls all four differential switch banks. When SEL = 0, each COM_ connects to its corresponding NC_ terminal; when SEL = 1, each COM_ connects to its NO_ terminal. This synchronous 4-lane control simplifies firmware and eliminates inter-lane skew caused by staggered switching-critical for HDMI pixel-clock alignment in the MAX4886ETO+.
Is the exposed paddle (EP) on the MAX4886ETO+ electrically connected internally?
No-the exposed paddle (EP) on the MAX4886ETO+ is not internally connected to any die node; it is a thermal and mechanical feature only. Per the datasheet, EP must be externally soldered to a solid PCB ground plane to ensure proper heat dissipation and RF grounding. Leaving EP unconnected degrades thermal performance and may compromise high-frequency signal return paths in the MAX4886ETO+.
