Product details
Overview
The MAX4760ETX+ 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 signal handling and 0.03% typical THD.
For engineers reviewing the MAX4760ETX+ datasheet, MAX4760ETX+ pinout, MAX4760ETX+ application, or MAX4760ETX+ equivalent, this device supports low-skew (<0.2ns), high-bandwidth signal routing in space-constrained portable electronics where precise channel matching (0.2Ω typ ΔRON), flat on-resistance (0.8Ω typ flatness), and minimal charge injection (15pC) are critical.
Technical Context
The MAX4760ETX+ implements four independent DPDT switches-each with separate normally open (NO), normally closed (NC), and common (COM) terminals-controlled by four dedicated logic inputs (INA–IND). Its CMOS architecture enables bidirectional signal flow across the full 0V to V+ analog range without degradation in on-resistance flatness or channel matching.
Designed for mixed-voltage systems, its digital inputs accept logic levels up to +5.5V regardless of supply voltage, supporting rail-to-rail control with low 1µA input leakage and 1.4V–2.0V VIH thresholds depending on V+. The device guarantees break-before-make timing of 2ns and operates across –40°C to +85°C in a thermally enhanced 36-pin TQFN-EP package.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4760AEWX+T | Same quad DPDT function but in 36-bump UCSP (3mm × 3mm); lower profile, higher thermal resistance; identical electrical specs except VIH/VIL thresholds optimized for 1.8V logic | Better suited for ultra-thin mobile designs where board area and height are constrained; less suitable for high-power dissipation scenarios | Select MAX4760AEWX+T when footprint and thickness are prioritized over thermal performance and hand-solderability |
| MAX4761ETX+T | Octal SPDT configuration (8 single-pole switches) vs. quad DPDT; same package, supply range, and bandwidth; shares 2.0Ω RON and 54pF CCOM(ON) but lacks paired switching control | Preferred for discrete signal routing (e.g., 8-channel sensor mux) rather than differential or dual-path applications requiring coordinated NO/NC action | Choose MAX4761ETX+T when independent channel control is needed across more endpoints, not paired pole operation |
Compared with MAX4760AEWX+T, the MAX4760ETX+ offers superior thermal dissipation (2105mW vs. 1221mW) and easier assembly in TQFN format; versus MAX4761ETX+T, it provides deterministic DPDT behavior essential for USB differential pair and stereo audio switching where polarity coordination matters.

FAQ
What is the maximum analog signal voltage range supported by the MAX4760ETX+?
The MAX4760ETX+ supports rail-to-rail analog signals from 0V to V+, where V+ ranges from +1.8V to +5.5V. Signals exceeding these limits are clamped by internal diodes; forward diode current must be limited to the rated ±100mA continuous current. This allows direct interfacing with 3.3V and 5V logic domains without level-shifting circuitry.
Does the MAX4760ETX+ support USB 2.0 full-speed operation?
Yes, the MAX4760ETX+ is explicitly USB 1.1 and USB 2.0 full-speed (12Mbps) signal-switching compliant. Its 150MHz -3dB bandwidth, 54pF COM-on capacitance, and <0.2ns channel-to-channel skew ensure signal integrity meets USB eye diagram requirements without added jitter or attenuation.
How does the MAX4760ETX+ handle power-supply sequencing?
The MAX4760ETX+ requires V+ to be applied before analog signals to prevent latch-up. If sequencing cannot be guaranteed and analog inputs exceed current limits, an external blocking diode (as shown in Figure 1 of the datasheet) must be added. The MAX4760ETX+ itself does not include integrated overvoltage protection beyond internal clamp diodes.
What is the purpose of the exposed pad (EP) on the MAX4760ETX+ TQFN package?
The exposed pad (EP) on the MAX4760ETX+ TQFN package must be soldered to a GND plane for optimal thermal dissipation and electrical performance. It reduces junction-to-board thermal resistance, enabling the device to sustain 2105mW continuous power dissipation at +70°C ambient, and improves noise immunity by lowering ground impedance.
Can the MAX4760ETX+ be used in audio applications requiring low total harmonic distortion?
Yes, the MAX4760ETX+ delivers 0.03% typical THD at 20Hz–20kHz with 1VP-P signal and 600Ω load, making it suitable for high-fidelity headphone switching and line-level audio routing. Its low on-resistance flatness (0.8Ω typ) and rail-to-rail capability preserve dynamic range and minimize crossover distortion in AC-coupled paths.
