Product details
Overview
The MAX4761EWX+T from Maxim Integrated is an octal SPDT analog switch IC designed for high-speed data and audio signal routing in compact portable systems. It operates from a single +1.8V to +5.5V supply, delivers 2.0Ω (typ) on-resistance, 54pF (typ) COM-on capacitance, and supports 150MHz (typ) -3dB bandwidth - enabling USB 2.0 full-speed (12Mbps) signal switching with less than 0.2ns skew.
For engineers reviewing the MAX4761EWX+T datasheet, MAX4761EWX+T pinout, MAX4761EWX+T application, or MAX4761EWX+T equivalent, this page provides verified electrical parameters, package mapping to the 36-bump UCSP (3mm × 3mm), functional pin roles, real-world use cases in USB/audio routing, and two validated alternative parts with documented technical and application differences.
Technical Context
The MAX4761EWX+T implements eight independent SPDT switches with rail-to-rail analog signal handling (0V to V+), bidirectional signal paths, and break-before-make timing (2ns typ). Its logic interface features a single control input (INA) and active-low enable (EN), allowing global switch disable without affecting individual channel states.
It uses CMOS process technology and integrates low-charge-injection (15pC typ) and low THD (0.03% typ) circuitry optimized for audio fidelity and high-speed digital integrity. The device is fully specified across –40°C to +85°C and supports mixed-voltage logic inputs up to +5.5V regardless of V+ level.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Octal SPDT analog switch - routes one common signal between two paths per channel |
| On-Resistance (RON) | 2.0Ω (typ) at V+ = 2.7V, ICOM = 10mA - ensures minimal voltage drop and power loss in signal paths |
| -3dB Bandwidth | 150MHz (typ) - supports USB 2.0 full-speed (12Mbps) data switching without attenuation |
| COM On-Capacitance | 54pF (typ) - enables fast edge response and low signal distortion in high-frequency routing |
| Supply Voltage Range | +1.8V to +5.5V - compatible with Li-ion battery, 3.3V, and 5V system rails |
| THD | 0.03% (typ) at 20Hz–20kHz - preserves audio signal integrity in headphone and codec interfaces |
| Turn-On/Off Time | 150ns / 60ns (typ, MAX4761) - enables precise timing control in synchronous data routing |
Pinout & Package
The MAX4761EWX+T is packaged in a 36-bump UCSP (3mm × 3mm) wafer-level chip-scale package with bottom-side solder bumps; the exposed die attach area is not electrically connected and requires no grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA | Digital Control Input | Single logic input controlling all eight SPDT switches; high = connect COM to NO, low = connect COM to NC |
| EN | Active-Low Enable | Drives all switches into high-impedance state when high; required for power-gating and isolation |
| 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; otherwise open-circuit |
| NC1–NC8 | Normally Closed Terminals | Connected to corresponding COM when INA = low; otherwise open-circuit |
| V+ | Positive Supply | Single 1.8V–5.5V rail powering analog and digital sections; bypass with 0.1µF to GND |
| GND | Ground Reference | Common return for supply and signal paths; connects to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog operation | Supports full 0V to V+ signal swing without clipping or distortion - essential for audio line-level and USB differential signaling |
| Low 0.2ns skew | Ensures matched propagation delay across all eight channels - critical for maintaining signal integrity in parallel data buses |
| 0.8Ω on-resistance flatness | Maintains consistent RON over entire analog voltage range - minimizes harmonic generation in audio paths |
| USB 2.0 full-speed compliance | Validated for 12Mbps signal switching with >80dB off-isolation and >95dB crosstalk rejection - meets USB electrical spec requirements |
| 1.8V logic-compatible control | Accepts 1.4V VIH (min) at V+ = 2.7V - interoperable with low-voltage microcontrollers and baseband processors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4761ETX+T | Same electrical specs but in 36-pin TQFN-EP (6mm × 6mm); includes exposed thermal pad tied to GND | Better thermal performance in high-current or continuous-switching scenarios; requires larger PCB footprint | Select when board layout allows 6mm × 6mm area and thermal dissipation >2W is needed |
| TMUX1574RTER | Quad SPDT (not octal); 3.5Ω RON (typ); 100MHz bandwidth; 1.2V–5.5V supply; no EN pin | Lacks global enable and half the channel count; lower integration density; higher RON increases insertion loss | Choose only if octal configuration is unnecessary and cost reduction outweighs performance trade-offs |
Compared with MAX4761ETX+T, the MAX4761EWX+T offers identical switching performance in a 3× smaller footprint ideal for ultra-portables; compared with TMUX1574RTER, it delivers double channel count, lower RON, higher bandwidth, and dedicated enable control - making it superior for USB/audio multiplexing where space and signal fidelity are critical.

FAQ
What is the maximum analog signal voltage range supported by the MAX4761EWX+T?
The MAX4761EWX+T supports rail-to-rail analog signals from 0V to V+, where V+ ranges from +1.8V to +5.5V. This means the device passes signals across the full supply range without clipping - for example, with V+ = 3.3V, analog inputs can swing from 0V to 3.3V. Internal ESD clamps limit absolute maximum analog voltage to V+ + 0.3V, so exceeding this risks damage.
Does the MAX4761EWX+T require external pull-up or pull-down resistors on its digital control pins?
No, the MAX4761EWX+T does not require external biasing on INA or EN. Its digital inputs have CMOS-compatible thresholds (VIH min = 1.4V at V+ = 2.7V; VIL max = 0.6V at V+ = 5.25V) and ≤1µA leakage current. Driving these pins directly from MCU GPIOs - even at different logic voltages up to +5.5V - is fully supported without external resistors.
How does the enable (EN) pin function in the MAX4761EWX+T?
The EN pin on the MAX4761EWX+T is an active-low global enable. When EN is low, the eight SPDT switches operate normally under INA control. When EN is high, all COM terminals enter high-impedance state - disconnecting both NO and NC paths regardless of INA logic level. This provides hardware-level isolation for power sequencing or fault containment.
Can the MAX4761EWX+T be used for bidirectional USB 2.0 data switching?
Yes, the MAX4761EWX+T is explicitly designed and tested for USB 1.1 and USB 2.0 full-speed (12Mbps) signal switching. Its 150MHz bandwidth, <0.2ns channel-to-channel skew, >80dB off-isolation, and <25pF NO/NC off-capacitance meet USB electrical compliance requirements for bidirectional D+/D− path selection in host-peripheral reconfiguration.
What is the thermal performance difference between the UCSP and TQFN packages of the MAX4761EWX+T?
The MAX4761EWX+T in 36-bump UCSP has a thermal resistance (θJA) of ~120°C/W (estimated), while the TQFN variant (MAX4761ETX+T) achieves ~55°C/W due to its exposed thermal pad. Under 100mA per channel (worst-case), the UCSP may rise ~12°C above ambient, whereas the TQFN stays within ~5°C - making the TQFN preferable for sustained high-current operation, though the UCSP remains suitable for typical portable duty cycles.
