Product details
Overview
The MAX4760EBX+ from Maxim Integrated is a quad double-pole/double-throw (DPDT) analog switch IC operating from a single +1.8V to +5.5V supply, featuring 2.0Ω typical on-resistance, 54pF typical COM-on capacitance, and 150MHz typical -3dB bandwidth. It routes high-speed data and audio signals in USB 1.1/2.0 full-speed (12Mbps) signal-switching applications with rail-to-rail analog signal handling and 0.03% typical THD.
For engineers reviewing the MAX4760EBX+ datasheet, MAX4760EBX+ pinout, MAX4760EBX+ application, or MAX4760EBX+ equivalent, this device is selected for low-skew (≤0.2ns), low-capacitance signal routing where channel matching (0.2Ω typ ΔRON), on-resistance flatness (0.8Ω typ), and break-before-make timing (2ns) are critical in portable audio and high-bandwidth data path designs.
Technical Context
The MAX4760EBX+ implements four independent DPDT switches controlled by four logic inputs (INA–IND), each pair sharing one control line. Its CMOS architecture supports bidirectional signal flow across NO_, NC_, and COM_ terminals with guaranteed rail-to-rail analog voltage range (0V to V+) and minimal on-resistance variation over temperature and signal voltage.
It features integrated digital input tolerance up to +5.5V regardless of supply voltage, enabling mixed-voltage system interfacing. The device uses a break-before-make switching sequence (2ns min) to prevent momentary shorting, and its low charge injection (15pC typ) minimizes transient glitches during switching transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V - supports single-supply operation across battery-powered and 3.3V/5V systems without level-shifting. |
| On-Resistance (RON) | 2.0Ω typical - enables low insertion loss and minimal signal attenuation in audio/data paths. |
| -3dB Bandwidth | 150MHz typical - supports USB 2.0 full-speed (12Mbps) data rates and wideband audio frequencies. |
| COM On-Capacitance | 54pF typical - ensures minimal loading on high-frequency source drivers and preserves signal integrity. |
| Channel Matching (ΔRON) | 0.2Ω typical - maintains amplitude balance between parallel signal paths in stereo or differential routing. |
| Break-Before-Make Time | 2ns minimum - prevents signal shorting during state transitions in multiplexed analog buses. |
| THD | 0.03% typical - preserves fidelity in audio switching applications such as headphone routing. |
| Operating Temperature | -40°C to +85°C - qualified for industrial and portable consumer environments including cellular phones and notebooks. |
Pinout & Package
The MAX4760EBX+ is packaged in a 36-bump UCSP (3mm × 3mm) with bottom-side solder bumps; the exposed die pad is not electrically connected and requires no grounding per Maxim's package documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA–IND | Digital control inputs | Four independent logic inputs controlling switch pairs (INA→SW1/SW2, INB→SW3/SW4, etc.); accept 0V to +5.5V logic levels regardless of V+. |
| COM1–COM8 | Analog common terminals | Bidirectional signal ports - serve as inputs or outputs depending on switch state; support rail-to-rail analog signals (0V to V+). |
| NO1–NO8 / NC1–NC8 | Normally open / normally closed terminals | Two analog paths per switch; NO_ conducts when control input is HIGH (MAX4760), NC_ conducts when LOW - enables flexible signal path selection. |
| V+ | Positive supply | Single power rail for analog and digital sections; bypassing with 0.1µF capacitor to GND is required for noise immunity. |
| GND | Ground reference | Common return for supply and analog signals; all internal circuitry referenced to this node. |
| N.C. | No connection | 11 pins (TQFN) or 8 pins (UCSP) marked N.C. - must remain unconnected; no internal bonding or functionality. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports 0V to V+ input/output swing without clipping - essential for full-scale audio and data signals in portable devices. |
| 0.2ns typical skew between channels | Minimizes timing mismatch in differential or parallel signal paths - critical for USB D+/D− or stereo L/R routing. |
| 0.8Ω typical on-resistance flatness | Ensures consistent gain and impedance across full analog signal range - improves linearity in audio switching. |
| 15pC typical charge injection | Reduces output voltage glitch during switching - avoids audible pop/click in headphone applications. |
| 80dB typical off-isolation at 100kHz | Prevents crosstalk between inactive channels - maintains signal purity in multi-source routing (e.g., mic vs. line-in). |
| 5.5V-tolerant digital inputs | Enables direct interface with 5V microcontrollers or FPGAs without external level shifters - simplifies system design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4760ETX+ | Same electrical specs but in 36-pin TQFN-EP (6mm × 6mm) package with exposed thermal pad; higher thermal dissipation (2105mW vs. 1221mW). | Preferred for thermally constrained PCB layouts requiring enhanced heat sinking; not drop-in compatible due to different footprint and bump vs. leaded termination. | Select MAX4760ETX+ when board-level thermal management is critical and TQFN assembly infrastructure exists. |
| TS5A3159DGSR | Single SPDT switch (not DPDT), 0.75Ω RON, 125MHz bandwidth, 5-pin SC70 package; lacks quad-DPDT topology and USB-compliant skew performance. | Suitable only for simple single-path switching; cannot replace MAX4760EBX+ in stereo or differential routing without redesigning signal path count and control logic. | Choose TS5A3159DGSR only for cost-sensitive, low-channel-count applications where DPDT functionality and sub-0.2ns skew are unnecessary. |
Compared with MAX4760ETX+ and TS5A3159DGSR, the MAX4760EBX+ uniquely delivers quad-DPDT topology in a 3mm × 3mm UCSP with verified USB 2.0 signal-switching compliance, making it irreplaceable in space-constrained, high-integration portable audio and data routing designs.

FAQ
What is the maximum analog signal voltage range supported by the MAX4760EBX+?
The MAX4760EBX+ supports rail-to-rail analog signals from 0V to V+, where V+ ranges from +1.8V to +5.5V. This allows full-scale signal handling without clipping in both audio and data applications, and internal clamping diodes protect against overvoltage transients up to V+ + 0.3V on COM_, NO_, and NC_ terminals.
Does the MAX4760EBX+ require external level-shifting when driven by a 5V microcontroller?
No - the MAX4760EBX+ digital inputs (INA–IND) tolerate voltages up to +5.5V regardless of the V+ supply voltage. When V+ = 1.8V or 3.3V, these inputs still accept 0V/5V logic levels directly, eliminating the need for external level shifters in mixed-voltage systems.
How does the MAX4760EBX+ ensure signal integrity in USB 2.0 full-speed applications?
The MAX4760EBX+ meets USB 2.0 full-speed (12Mbps) signal-switching requirements via 150MHz -3dB bandwidth, ≤0.2ns channel skew, 54pF COM-on capacitance, and 80dB off-isolation at 100kHz. These parameters collectively preserve rise/fall times, minimize jitter, and suppress crosstalk in D+/D− differential pairs.
What is the thermal performance difference between the MAX4760EBX+ UCSP and MAX4760ETX+ TQFN packages?
The MAX4760EBX+ in 36-bump UCSP has a continuous power dissipation of 1221mW at +70°C (derated 15.3mW/°C above), while the MAX4760ETX+ in 36-pin TQFN offers 2105mW (derated 26.3mW/°C). The TQFN's exposed pad provides superior thermal conduction, making it preferable in high-power-density layouts.
Can the MAX4760EBX+ be used for RF antenna switching in cellular handsets?
Yes - the MAX4760EBX+ supports RF front-end switching up to 150MHz bandwidth with low on-resistance (2.0Ω typ), low charge injection (15pC typ), and 2ns break-before-make timing. Its performance is validated in LTE/WCDMA band switching applications where low insertion loss and fast TDD mode transitions are required.
