Product details
Overview
MAX4717EBC+T from Maxim Integrated is a dual SPDT analog switch optimized for USB 1.1 and low-voltage audio signal routing, featuring two 4.5Ω (max) RON switches, <80ns tON, >300MHz bandwidth, and rail-to-rail signal handling in a 2.0mm × 1.50mm UCSP package.
For engineers reviewing the MAX4717EBC+T datasheet, MAX4717EBC+T pinout, MAX4717EBC+T application, or MAX4717EBC+T equivalent, this page delivers verified electrical specs, UCSP bump mapping, USB-compliant timing performance, leakage and distortion data, and direct alternatives for signal-path design validation.
Technical Context
The MAX4717EBC+T implements break-before-make switching with 1ns guaranteed tBBM, enabling safe channel reconfiguration in bidirectional data paths. Its BiCMOS process delivers matched on-resistance (≤0.3Ω ΔRON) and flatness (≤1.2Ω) across the full analog range (0V to V+), critical for low-distortion audio and precise USB D+/D− switching.
It supports single-supply operation from +1.8V to +5.5V with +1.8V logic-compatible inputs, and achieves -55dB off-isolation and -80dB crosstalk at 10MHz-key for noise-sensitive mixed-signal systems requiring high channel separation and minimal signal degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RON (max) | 4.5Ω per SPDT switch at +3V supply - ensures minimal insertion loss in 50Ω/600Ω signal paths |
| ΔRON (max) | 0.3Ω matching between channels at +3V - preserves amplitude balance in differential pairs like USB D+/D− |
| tON/tOFF | <80ns / <40ns at +2.7V - enables reliable 12Mbps USB 1.1 data switching without timing violation |
| Bandwidth | >300MHz (-3dB) - supports high-fidelity audio and fast digital signal routing without roll-off |
| CON | 15pF - limits capacitive loading on source drivers and maintains signal integrity in high-speed traces |
| THD | 0.03% at 2VP-P - meets fidelity requirements for line-level audio and precision instrumentation |
| Off-isolation | -55dB at 10MHz - suppresses coupling between inactive channels in multi-source routing |
Pinout & Package
MAX4717EBC+T is housed in a 12-bump UCSP (4×3 array, 0.5mm pitch), occupying only 2.0mm × 1.50mm PCB area. The chip-scale package features solder bumps on the die side (bump-side-down mounting) and requires no leadframe or wire bonds.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | NC2 | Analog Switch 2 Normally Closed terminal - connects to COM2 when IN2 = LOW |
| A2 | IN2 | Digital control input for Switch 2 - TTL/CMOS compatible, accepts up to +5.5V regardless of V+ |
| A3 | COM2 | Common terminal for Switch 2 - bidirectional I/O node for signal path routing |
| A4 | NO2 | Analog Switch 2 Normally Open terminal - connects to COM2 when IN2 = HIGH |
| B1 | GND | Ground reference for analog and digital circuitry - must be low-impedance for THD and noise performance |
| B4 | V+ | Positive supply input (1.8V–5.5V) - powers internal logic and analog switch FETs |
| C1 | NC1 | Analog Switch 1 Normally Closed terminal - connects to COM1 when IN1 = LOW |
| C2 | IN1 | Digital control input for Switch 1 - independent logic control enables asynchronous channel selection |
| C3 | COM1 | Common terminal for Switch 1 - shared node for dual-path USB or stereo audio routing |
| C4 | NO1 | Analog Switch 1 Normally Open terminal - connects to COM1 when IN1 = HIGH |
Key Features
| Feature | Design Value |
|---|---|
| USB 1.1 compliance (TID = 4000231) | Guaranteed ≤2ns differential skew between D+/D− paths - satisfies USB 1.1 timing margin for host/peripheral interconnect |
| Rail-to-rail signal handling | Full 0V to V+ analog range support - eliminates clipping in battery-powered audio and sensor interfaces |
| Break-before-make switching | 1ns minimum tBBM - prevents momentary short-circuits during channel transitions in power-sensitive systems |
| Low 15pF on-channel capacitance | Minimizes high-frequency attenuation and phase shift - preserves signal integrity up to 300MHz |
| +1.8V logic compatibility | VIH = 1.4V (at +3V supply), VIL = 0.5V - enables direct interface with low-voltage microcontrollers and FPGAs |
Applications
| USB 1.1 Peripheral Multiplexing | Portable Audio Signal Routing |

Use Value: Preserves audio fidelity across sources while consuming <1µA quiescent current - extends battery life in always-on audio paths. |
| Low-Voltage Data Acquisition | Headphone Jack Detection & Routing |
Use Scenario: Multiplexing sensor inputs (e.g., thermistor, photodiode) into a single ADC channel in a wearable health monitor. IC Role / Device Role / Timing Role: Dual SPDT provides isolated analog front-end switching with <1nA leakage at +25°C to prevent measurement drift.

Use Scenario: Detecting 3.5mm jack insertion and routing microphone/ground/sleeve signals to appropriate codec pins in a tablet. IC Role / Device Role / Timing Role: One SPDT handles mic bias path; the other routes ground/sleeve detection - both operate from same 1.8V supply. Use Value: Eliminates need for discrete MOSFETs or mechanical switches, reducing BOM count and PCB footprint by >60% vs. discrete solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4718EBC+T | Features one 4.5Ω SPDT and one 20Ω SPDT (vs. two 4.5Ω in MAX4717EBC+T); 0.4Ω RON match on high-RON channel | Optimized for mixed-sensitivity routing (e.g., USB D+/D− + mic bias), not symmetric differential paths | Select MAX4718EBC+T when asymmetric on-resistance is acceptable for cost or thermal trade-offs |
| TMUX1574RSVR | Single 4.5Ω SPDT (not dual); 1.8V–5.5V supply; 0.25Ω RON match; 300MHz bandwidth; 10-pin WQFN | Lacks second independent SPDT - requires two units for dual-channel use, increasing layout area and BOM count | Choose TMUX1574RSVR only for single-channel upgrades where UCSP footprint is not required |
Compared with MAX4718EBC+T and TMUX1574RSVR, the MAX4717EBC+T uniquely delivers matched dual 4.5Ω SPDTs in a space-constrained UCSP, making it optimal for USB 1.1 and stereo audio where channel symmetry, skew control, and minimal board area are non-negotiable.

FAQ
What is the maximum supply voltage rating for MAX4717EBC+T?
The MAX4717EBC+T has an absolute maximum supply voltage (V+) of +6.0V, but its specified operational range is +1.8V to +5.5V. Operating above +5.5V risks permanent damage and violates the device's qualified electrical specifications. For robust design, maintain V+ within the 1.8V–5.5V range and observe proper power-supply sequencing (apply V+ before analog signals).
Does MAX4717EBC+T support true bidirectional signal flow?
Yes, the MAX4717EBC+T supports fully bidirectional analog signal routing on all COM_, NO_, and NC_ terminals. Its CMOS-based switch architecture imposes no directionality - signals can pass from COM1 to NO1 or from NO1 to COM1 with identical RON, capacitance, and distortion characteristics, enabling flexible PCB layout in audio and data paths.
What is the guaranteed on-resistance matching between the two SPDT switches in MAX4717EBC+T?
The MAX4717EBC+T guarantees ≤0.3Ω maximum on-resistance matching (∆RON) between its two SPDT switches at +3.0V supply and +25°C. This tight matching ensures amplitude consistency in differential applications such as USB 1.1 D+/D− switching, where imbalance directly impacts eye diagram quality and bit-error rate.
Can MAX4717EBC+T be used with a 1.8V logic supply while operating from a 3.3V analog rail?
Yes - the MAX4717EBC+T digital inputs (IN1, IN2) are overvoltage-tolerant and accept logic levels up to +5.5V independent of V+. With V+ = +3.3V, VIH is 1.4V and VIL is 0.5V, so a 1.8V logic source meets both thresholds with margin. This allows seamless interfacing with low-voltage MCUs without level-shifting circuitry.
Is the UCSP package of MAX4717EBC+T compatible with standard reflow profiles?
Yes, the MAX4717EBC+T UCSP package is qualified for standard lead-free reflow profiles, including vapor-phase (60s at +215°C) and infrared (15s at +220°C). Maxim specifies bump-temperature limits and recommends following the latest UCSP reflow profile published at maxim-ic.com/ucsp to ensure void-free solder joints and mechanical reliability.
