Product details
Overview
MAX4760ETX+T from Maxim Integrated is a quad double-pole/double-throw (DPDT) analog switch IC operating from +1.8V to +5.5V, 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 2.0 full-speed (12Mbps) switching applications with rail-to-rail signal handling and 0.03% typical THD.
For engineers reviewing the MAX4760ETX+T datasheet, MAX4760ETX+T pinout, MAX4760ETX+T application, or MAX4760ETX+T equivalent, key selection criteria include its quad DPDT topology, TQFN-EP package with exposed pad, low skew (<0.2ns), channel-to-channel on-resistance matching (0.2Ω typ), and compatibility with mixed-voltage logic control up to +5.5V.
Technical Context
The MAX4760ETX+T implements four independent DPDT switches-each with separate NO/NC/COM terminals-controlled by four dedicated logic inputs (INA–IND), enabling paired switching of differential or dual-path signals. Its CMOS process delivers rail-to-rail analog operation and bidirectional signal routing without polarity constraints.
It guarantees 2.0Ω typical on-resistance across the full 0V to V+ analog range, with flatness of ±0.8Ω and channel matching of ±0.2Ω, supporting precise signal integrity in audio and data paths. Break-before-make timing is 2ns, minimizing transient shorts during state transitions.

Pinout & Package
MAX4760ETX+T is housed in a 36-pin TQFN-EP (6mm × 6mm) package with exposed thermal pad (EP) connected to GND. Pin numbering follows standard top-view orientation; EP must be soldered to a GND plane for thermal and electrical performance.

| 2 (B2) | COM2 | Common terminal of Switch 2 - bidirectional I/O path routed to NO2 or NC2 based on INB |
| 3 (A2) | NC2 | Normally closed terminal of Switch 2 - provides alternate path when INB = LOW |
| 4 (A3) | INA | Digital control input for Switches 1 & 2 - active-HIGH logic enables NO1/NO2 conduction |
| 5 (C3,D4) | V+ | Positive supply rail - powers analog and digital sections; bypass with 0.1µF to GND |
| 6 (A4) | INB | Digital control input for Switches 3 & 4 - independent pairing enables simultaneous dual-path control |
| 36 (B1) | COM1 | Common terminal of Switch 1 - central node for signal routing between NO1 and NC1 |
| EP | Exposed Pad | Thermal and electrical ground connection - mandatory for thermal dissipation and noise reduction |

FAQ
What is the maximum analog signal voltage range supported by the MAX4760ETX+T?
The MAX4760ETX+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, 0V to 3.3V with a 3.3V supply or 0V to 5.0V with a 5V supply - enabling direct interfacing with unbuffered audio and data sources.
Does the MAX4760ETX+T require external level-shifting when controlled by a 1.8V logic microcontroller?
No, the MAX4760ETX+T does not require external level-shifting. Its digital inputs accept voltages up to +5.5V regardless of V+, so a 1.8V microcontroller can drive INA–IND directly. However, note that the MAX4760ETX+T uses standard TTL thresholds (VIH = 2.0V min at V+ ≥ 3.6V), so ensure the MCU's HIGH output exceeds 2.0V under load for reliable operation.
How is thermal management handled in the MAX4760ETX+T package?
The MAX4760ETX+T uses a 36-pin TQFN-EP package with an exposed thermal pad (EP) that must be soldered to a PCB GND plane. This pad provides the primary thermal path - derating is 26.3mW/°C above +70°C, with 2105mW max continuous power dissipation at TA = +70°C. Proper EP connection is mandatory to maintain junction temperature below +150°C under full load.
Can the MAX4760ETX+T be used in bidirectional signal paths such as USB D+ and D−?
Yes, the MAX4760ETX+T supports fully bidirectional analog signal routing. Its DPDT architecture allows NO_, NC_, and COM_ terminals to function interchangeably as inputs or outputs. This makes it suitable for USB 2.0 full-speed (12Mbps) differential pair switching, provided layout maintains controlled impedance and minimizes skew between paired channels.
What is the significance of the 0.2Ω typical on-resistance matching specification for the MAX4760ETX+T?
The 0.2Ω typical channel-to-channel on-resistance matching (ΔRON) ensures amplitude consistency across all four DPDT switches. In applications like stereo audio routing or differential data switching, this tight matching prevents gain imbalance, phase distortion, or common-mode error - directly contributing to the 0.03% THD and <0.2ns skew performance cited in the MAX4760ETX+T datasheet.
