Product details
Overview
MAX4761EBX from Maxim Integrated is an octal single-pole/double-throw (SPDT) analog switch optimized for high-speed USB 1.1/2.0 full-speed signal routing and audio switching. It operates from a single +1.8V to +5.5V supply, delivers 3.5Ω max on-resistance, 25pF off-capacitance, and supports rail-to-rail analog signals up to 325MHz bandwidth in portable communications devices.
For engineers reviewing the MAX4761EBX datasheet, MAX4761EBX pinout, MAX4761EBX application, or MAX4761EBX equivalent, this page provides verified technical context, package-specific pin mapping, real-world use scenarios in USB/audio routing, and two confirmed alternative parts with documented functional and layout trade-offs.
Technical Context
The MAX4761EBX implements eight independent SPDT switches with break-before-make timing (2ns typical), sub-0.2ns skew, and 0.03% THD at 20Hz–20kHz - enabling precise, low-distortion signal path selection. Its logic interface accepts rail-to-rail inputs up to +5.5V regardless of V+ level, supporting mixed-voltage system control.
All switches feature matched on-resistance (0.2Ω channel-to-channel), flat on-resistance (±0.8Ω over full signal range), and bidirectional signal handling. The device guarantees 100dB off-isolation and 95dB crosstalk at 100kHz, critical for noise-sensitive data and audio paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Octal SPDT analog switch - routes one common terminal between two alternate paths per channel |
| On-Resistance (max) | 3.5Ω at V+ = 2.7V - ensures minimal insertion loss and voltage drop in signal chains |
| Off-Capacitance | 25pF per NO/NC terminal - preserves high-frequency integrity for USB 2.0 full-speed (480Mbps) signals |
| -3dB Bandwidth | 325MHz - supports clean pass-through of harmonics up to 5th order for 65MHz digital clocks |
| Supply Range | +1.8V to +5.5V - enables direct interfacing with 1.8V, 3.3V, and 5V logic and analog domains |
| THD | 0.03% at 1VP-P, 20Hz–20kHz - meets high-fidelity audio routing requirements without audible distortion |
| Break-Before-Make | 2ns typical - prevents momentary shorting during channel transitions in sensitive analog paths |
Pinout & Package
MAX4761EBX is packaged in a 32-bump UCSP (3mm × 3mm), distinct from the 36-bump variant used in other MAX4761 versions. This compact chip-scale package features an exposed thermal pad connected to GND and requires specific PCB bump-pad layout per Maxim Application Note UCSP.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA | Digital control input | Single logic input controlling all eight SPDT switches; active-high enable when EN is asserted |
| EN | Enable input (active-low) | Disables all switches simultaneously; places COM terminals in high-impedance state when high |
| COM1–COM8 | Analog common terminals | Bidirectional signal ports - serve as inputs or outputs depending on routing configuration |
| NO1–NO8 | Normally open terminals | Connected to corresponding COMx when INA = high and EN = low; isolated otherwise |
| NC1–NC8 | Normally closed terminals | Connected to corresponding COMx when INA = low and EN = low; isolated otherwise |
| V+ | Positive supply | Single power rail for analog and digital sections; bypassing with 0.1µF to GND required for noise immunity |
| GND | Ground reference | Reference for all analog signals and digital logic; must connect exposed pad to GND plane |
Key Features
| Feature | Design Value |
|---|---|
| USB 2.0 Full-Speed Compliance | Validated 25pF off-capacitance and 325MHz bandwidth meet eye-diagram and jitter specs for 480Mbps signaling |
| Rail-to-Rail Signal Handling | Supports analog inputs from 0V to V+ without clipping - essential for unbuffered audio and data lines |
| Low THD (0.03%) | Enables transparent audio path switching in headset and speaker routing without perceptible degradation |
| Mixed-Voltage Logic Interface | IN/EN accept 0V to +5.5V logic levels independent of V+, simplifying integration with 5V microcontrollers driving 3.3V switches |
| Channel Matching (0.2Ω ΔRON) | Ensures consistent gain/attenuation across parallel signal paths - critical for stereo audio balance and differential data pairs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4761ETX | Same electrical specs but in 36-pin thin QFN (6mm × 6mm); includes 4 no-connect pins not present in EBX UCSP | Requires larger PCB footprint and different thermal pad layout; better suited for prototyping or higher-power dissipation scenarios | Select ETX for manual assembly, thermal testing, or when board space permits larger package |
| TS5A3159DBVR | Single SPDT, 0.75Ω RON, 9pF COFF, 200MHz BW; 6-pin SOT-23 - not pin-compatible, lower channel count | Requires eight discrete units to match MAX4761EBX functionality; increases layout complexity and total capacitance | Choose only for ultra-low RON or space-constrained single-channel needs - not a functional replacement |
Compared with MAX4761ETX, the MAX4761EBX saves 33% board area and improves thermal coupling via its 32-bump UCSP layout; versus TS5A3159DBVR, it delivers integrated octal control with guaranteed skew matching and USB-compliant bandwidth - eliminating inter-device timing variation.

FAQ
What is the maximum operating frequency supported by MAX4761EBX?
The MAX4761EBX has a specified -3dB bandwidth of 325MHz, validated under 5pF load and 50Ω termination. This enables reliable operation with USB 2.0 full-speed (480Mbps) signals and clock harmonics up to the 5th order. Performance remains stable across the full -40°C to +85°C temperature range per datasheet Figure 15.
Does MAX4761EBX support rail-to-rail analog signal switching?
Yes, MAX4761EBX supports rail-to-rail analog signal handling from 0V to V+. Its analog switches maintain low on-resistance flatness (±0.8Ω) and minimal THD (0.03%) across the entire signal range, as confirmed in the Electrical Characteristics table and Typical Operating Characteristics plots (toc02–toc03).
How does the enable (EN) pin function on MAX4761EBX?
The EN pin on MAX4761EBX is an active-low enable that disables all eight SPDT switches when driven high. When EN = high, all COM terminals enter high-impedance state, isolating signal paths. When EN = low, switching is controlled solely by the INA logic input, as detailed in the Truth Table on page 12 of the datasheet.
What is the on-resistance matching specification for MAX4761EBX?
MAX4761EBX guarantees 0.2Ω channel-to-channel on-resistance matching (ΔRON) at V+ = 2.7V and ICOM = 10mA. This tight matching ensures uniform gain/attenuation across all eight channels, critical for stereo audio balance and differential signal integrity in data routing applications.
Is MAX4761EBX compatible with 1.8V logic control signals?
Yes, MAX4761EBX accepts logic inputs down to 0.5V (VIL) at V+ = 2.7V–3.6V, making it fully compatible with 1.8V CMOS logic. Its VIH threshold is 1.4V under those conditions, ensuring robust recognition of 1.8V high-level signals without level translation circuitry.
