Product details
Overview
The MAX4761ETX+T from Maxim Integrated is an octal SPDT 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-enabling high-fidelity USB 2.0 full-speed (12Mbps) signal routing in portable audio and data interfaces.
For engineers reviewing the MAX4761ETX+T datasheet, MAX4761ETX+T pinout, MAX4761ETX+T application, or MAX4761ETX+T equivalent, this device is selected for low-skew (≤0.2ns), rail-to-rail analog switching with minimal THD (0.03% typ) and precise channel matching (0.2Ω typ ΔRON) in space-constrained, battery-powered systems.
Technical Context
The MAX4761ETX+T implements eight independent SPDT switches controlled by a single logic input (INA) and an active-low enable (EN), supporting break-before-make operation (2ns typ) and bidirectional signal flow across 0V to V+ analog ranges. Its CMOS process ensures rail-to-rail signal handling and 1.8V–5.5V logic compatibility independent of supply voltage.
It delivers low dynamic distortion via 54pF COM-on capacitance and 25pF NO/NC-off capacitance, enabling clean 150MHz bandwidth performance with 95dB crosstalk rejection and 80dB off-isolation at 100kHz-critical for simultaneous audio/data multiplexing without coupling artifacts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4761EBX+T | Same electrical specs but in 36-bump UCSP (3mm × 3mm); no exposed pad; higher thermal resistance. | Better suited for ultra-thin handhelds where board height is constrained; less effective for high-duty-cycle thermal dissipation. | Select MAX4761EBX+T when footprint area is prioritized over thermal performance and solder-reflow compatibility with fine-pitch bump layout. |
| MAX4761AETX+T | Lower 1.8V logic threshold (VIH = 1.4V min); identical analog performance and pinout. | Enables direct interface with 1.8V GPIOs without level translation-ideal for modern low-voltage SoCs and PMIC-controlled systems. | Choose MAX4761AETX+T when host processor uses 1.8V logic and strict VIH/VIL margins are required for reliable control signaling. |
Compared with MAX4761EBX+T, the MAX4761ETX+T offers superior thermal management via its exposed pad and larger TQFN footprint, while MAX4761AETX+T adds 1.8V logic compatibility-making the original MAX4761ETX+T optimal for mixed-voltage designs needing robust thermal performance and USB 2.0 timing compliance.

FAQ
What is the maximum analog signal voltage range supported by the MAX4761ETX+T?
The MAX4761ETX+T supports rail-to-rail analog signals from 0V to V+, where V+ ranges from +1.8V to +5.5V. This allows full-swing operation without clipping when interfacing with ADCs, DACs, or audio codecs. Internal ESD protection diodes clamp signals exceeding V+ or GND, limiting forward current to ±100mA continuous-ensuring safe operation within specified absolute maximum ratings.
Does the MAX4761ETX+T require external level shifting for 1.8V logic control inputs?
No-the MAX4761ETX+T accepts logic inputs from 0V to +5.5V regardless of V+ supply voltage, eliminating need for external level shifters. However, the MAX4761AETX+T variant offers lower 1.8V-compatible logic thresholds (VIH = 1.4V min), making it preferable for strict 1.8V GPIO interfacing. The MAX4761ETX+T remains fully functional with 1.8V logic but operates with wider noise margins due to its higher VIH specification.
How does the EN pin function on the MAX4761ETX+T, and what is its pin location?
The EN pin on the MAX4761ETX+T is an active-low enable input that places all COM outputs in high-impedance state when driven high. It is located on pin 22 of the 36-pin TQFN-EP package. Driving EN low enables normal switching operation controlled by INA. This feature allows system-level power gating of analog paths without altering individual switch states-critical for low-power modes in battery-operated devices using the MAX4761ETX+T.
Can the MAX4761ETX+T be used for bidirectional analog signal routing?
Yes-the MAX4761ETX+T supports fully bidirectional signal flow: NO_, NC_, and COM_ terminals may serve as inputs or outputs interchangeably. This enables flexible use cases such as shared audio paths (e.g., microphone input and speaker output on same jack) or duplex data lines. The symmetric on-resistance (2.0Ω typ) and matched capacitance ensure consistent performance regardless of signal direction-verified across the full -40°C to +85°C operating range.
What is the thermal performance difference between the MAX4761ETX+T and MAX4761EBX+T packages?
The MAX4761ETX+T in 36-pin TQFN-EP features an exposed pad thermally connected to GND, delivering 2105mW continuous power dissipation at +70°C (derated 26.3mW/°C above). In contrast, the MAX4761EBX+T UCSP package has no exposed pad and dissipates only 1221mW at +70°C (derated 15.3mW/°C). This makes the MAX4761ETX+T better suited for sustained high-current switching or ambient temperatures exceeding +70°C-key for thermally demanding USB hub or audio amplifier applications.
