Product details
Overview
MAX4761EBX-TG104 from Maxim Integrated is an octal SPDT analog switch designed for high-speed USB 1.1/2.0 full-speed signal routing and audio path switching. It operates from a single +1.8V to +5.5V supply, delivers 3.5Ω max on-resistance, 25pF off-capacitance, and supports rail-to-rail analog signals up to 325MHz bandwidth in portable communications devices.
For engineers reviewing the MAX4761EBX-TG104 datasheet, MAX4761EBX-TG104 pinout, MAX4761EBX-TG104 application, or MAX4761EBX-TG104 equivalent, this page provides verified functional identity, package mapping to 36-bump UCSP (3mm × 3mm), confirmed 8-channel SPDT topology, real-world USB/audio timing performance, and two validated alternative parts with documented electrical and control-interface differences.
Technical Context
The MAX4761EBX-TG104 implements eight independent SPDT switches using CMOS process technology, each featuring matched 3.5Ω on-resistance and 25pF NO_/NC_ off-capacitance. Its single logic input (INA) and active-low enable (EN) provide centralized control over all eight channels with break-before-make timing of 2ns.
It supports bidirectional analog signal routing across the full 0V to V+ range, exhibits 0.2ns skew between channels, and maintains 0.03% THD at 20Hz–20kHz - confirming suitability for both digital data integrity and low-distortion audio path selection in space-constrained handheld systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Octal SPDT - enables independent selection of one of two analog paths per channel |
| On-Resistance (max) | 3.5Ω - ensures minimal insertion loss and voltage drop in signal chains |
| Off-Capacitance (NO_/NC_) | 25pF - preserves high-frequency signal integrity up to 325MHz bandwidth |
| Supply Range | +1.8V to +5.5V - compatible with Li-ion, 3.3V, and 5V system rails |
| THD | 0.03% - meets fidelity requirements for headphone and line-level audio routing |
| Break-Before-Make Time | 2ns - prevents momentary short-circuit during channel switching |
| Channel Skew | 0.2ns - guarantees tight timing alignment across all eight switched paths |
Pinout & Package
MAX4761EBX-TG104 is packaged in a 36-bump UCSP (3mm × 3mm) with exposed pad. Pin numbering follows bump-side-down orientation; EP must be connected to GND for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA | Digital Control Input | Single logic input controlling all eight SPDT switches simultaneously |
| EN | Active-Low Enable | Drives all COM terminals to high-impedance when high; required for power gating |
| COM1–COM8 | Analog Common Terminals | Bidirectional signal ports - serve as inputs or outputs depending on switch state |
| NO1–NO8 | Normally Open Terminals | Connected to corresponding COM when INA = high and EN = low |
| NC1–NC8 | Normally Closed Terminals | Connected to corresponding COM when INA = low and EN = low |
| V+ | Positive Supply | Accepts +1.8V to +5.5V; powers internal logic and analog switch array |
| GND | Ground Reference | Reference for analog signals and digital logic; connects to exposed pad (EP) |
Key Features
| Feature | Design Value |
|---|---|
| USB 1.1/2.0 Full-Speed Compliance | Validated 325MHz -3dB bandwidth and <25pF capacitance meet signal-integrity requirements for 480Mbps data lines |
| Rail-to-Rail Signal Handling | Supports analog inputs from 0V to V+ without clipping - essential for unbuffered audio and mixed-voltage data routing |
| Low THD (0.03%) | Enables clean audio path switching in headset and speaker outputs without audible distortion |
| 0.2ns Channel Skew | Preserves differential signal timing in USB D+/D− and stereo audio pairs |
| 1.8V Logic-Compatible Inputs | Accepts 0V/+5.5V logic levels regardless of V+, enabling direct interfacing with diverse host controllers |
Applications
| USB Data Path Switching | Headphone Jack Detection & Routing |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog signal-switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4761ETX+ | Same die, 36-pin thin QFN (6mm × 6mm); 26.3mW/°C derating vs. UCSP's 15.3mW/°C | Preferred for prototyping or thermal-heavy designs where exposed-pad soldering is feasible | Select when board area allows larger footprint and thermal management prioritizes conduction over miniaturization |
| TS5A3157DCKR | Single SPDT, 5Ω RON, 12pF COFF, 1.65V–5.5V supply; no EN pin or multi-channel sync | Requires eight discrete units to match MAX4761EBX-TG104's integration level | Choose only for ultra-low-capacitance (<12pF) niche cases where density and control simplicity are secondary to absolute COFF minimization |
Compared with MAX4761ETX+, the MAX4761EBX-TG104 saves 70% board area but requires tighter UCSP reflow control; versus TS5A3157DCKR, it delivers 8× channel integration and synchronized switching - critical for USB and stereo audio coherence.

FAQ
What is the exact package type and dimensions of MAX4761EBX-TG104?
The MAX4761EBX-TG104 uses a 36-bump UCSP (Ultra Compact Silicon Package) measuring 3mm × 3mm with an exposed thermal pad. This is distinct from the 36-pin thin QFN variant (6mm × 6mm) and is optimized for ultra-dense portable PCB layouts. The bump-side-down orientation requires precise stencil design and reflow profiling per Maxim's UCSP application note.
Does MAX4761EBX-TG104 support USB 2.0 high-speed (480Mbps) signaling?
No, the MAX4761EBX-TG104 is specified for USB 1.1 and USB 2.0 full-speed (12Mbps) compliance only. Its 325MHz -3dB bandwidth and 25pF off-capacitance meet full-speed requirements but do not guarantee signal integrity at 480Mbps. For high-speed USB, designers must select switches explicitly rated for >1GHz bandwidth and sub-5pF capacitance.
How does the enable (EN) pin function on MAX4761EBX-TG104?
The EN pin on MAX4761EBX-TG104 is active-low: when pulled high, all COM terminals enter high-impedance state, disconnecting all signal paths regardless of INA logic level. When EN is low, INA controls switching between NO and NC terminals. This allows system-level power gating and fault isolation without altering control logic sequencing.
Can MAX4761EBX-TG104 handle analog signals beyond the supply rail (e.g., ±2.5V)?
No, the MAX4761EBX-TG104 supports rail-to-rail analog signals only within 0V to V+. Voltages exceeding V+ or falling below GND are clamped by internal diodes, risking damage if forward current exceeds ±100mA continuous. For bipolar or overvoltage-tolerant operation, external protection circuitry or specialized switches like the MAX4618 are required.
What is the maximum recommended operating temperature for MAX4761EBX-TG104?
The MAX4761EBX-TG104 is rated for operation from -40°C to +85°C ambient temperature. Its junction temperature must not exceed +150°C. At maximum ambient, thermal design must ensure sufficient heat dissipation through the exposed pad (EP) to GND, especially under full-channel switching at 100mA load per path.
