Product details
Overview
The MAX4717ETB+TG51 from Maxim Integrated is a dual SPDT analog switch featuring two 4.5Ω (max) low-RON channels, rail-to-rail signal handling, and <80ns turn-on time at +2.7V - designed for USB 1.1 D+/D− switching and audio routing in space-constrained portable devices.
For engineers reviewing the MAX4717ETB+TG51 datasheet, MAX4717ETB+TG51 pinout, MAX4717ETB+TG51 application, or MAX4717ETB+TG51 equivalent, key selection criteria include guaranteed 0.3Ω RON matching, 300MHz bandwidth, 15pF on-capacitance, break-before-make timing (1ns), and TDFN-EP package compatibility with high-density PCB layouts.
Technical Context
The MAX4717ETB+TG51 implements dual independent SPDT switches using BiCMOS process technology, supporting single-supply operation from +1.8V to +5.5V with +1.8V logic-compatible digital inputs. Each switch provides break-before-make operation with tBBM ≤1ns and exhibits minimal RON variation (<1.2Ω flatness) across the full analog signal range (0V to V+).
It delivers differential skew ≤2ns between channels, -80dB crosstalk at 10MHz, and -55dB off-isolation at 10MHz - enabling clean signal routing in mixed-signal USB and audio paths without channel interference or signal degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RON (max) | 4.5Ω per SPDT channel at +2.7V - ensures minimal insertion loss for USB 1.1 (12Mbps) and audio signals |
| RON match (max) | 0.3Ω at +3.0V - enables precise signal balancing in differential paths like USB D+/D− |
| tON/tOFF | <80ns / <40ns at +2.7V - supports fast multiplexing in real-time audio and data acquisition |
| -3dB bandwidth | >300MHz - preserves signal integrity up to video and high-speed serial frequencies |
| On-channel capacitance | 15pF - limits capacitive loading on source drivers and maintains rise/fall time fidelity |
| Supply range | +1.8V to +5.5V - allows direct integration with Li-ion battery systems and 3.3V/5V logic domains |
| Logic compatibility | +1.8V CMOS input thresholds - enables interface with low-voltage microcontrollers without level shifters |
Pinout & Package
Packaged in a 10-pin TDFN-EP (3mm × 3mm, 0.8mm height) with exposed thermal pad, the MAX4717ETB+TG51 occupies minimal PCB area while enabling efficient heat dissipation in compact portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply rail | Accepts +1.8V to +5.5V; powers analog and digital sections; requires local 100nF bypass to GND |
| GND | Ground reference | Analog/digital common return; must be connected to exposed pad for thermal and noise performance |
| IN1, IN2 | Digital control inputs | +1.8V logic compatible; tolerate up to +5.5V regardless of V+, enabling mixed-voltage system interfacing |
| COM1, COM2 | Common analog terminals | Bidirectional signal ports; support rail-to-rail analog voltages from 0V to V+ |
| NO1, NO2 | Normally open analog terminals | Connected to COMx when corresponding INx = high; used for active signal paths |
| NC1, NC2 | Normally closed analog terminals | Connected to COMx when corresponding INx = low; provide default path during power-up or logic low |
| EP | Exposed thermal pad | Must be soldered to PCB ground plane for thermal management and EMI reduction |
Key Features
| Feature | Design Value |
|---|---|
| USB 1.1 compliance (TID #4000231) | Validated for D+/D− switching with ≤2ns differential skew and 12Mbps data integrity |
| Rail-to-rail signal handling | Supports analog signals from 0V to V+ without clipping - essential for headphone and line-level audio |
| Break-before-make switching | Guaranteed 1ns minimum dead time prevents momentary short-circuits during channel switching |

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 |
|---|---|---|---|
| MAX4717EUB+ | Same electrical specs; packaged in 10-pin µMAX (3.0mm × 3.0mm, 1.0mm height) instead of TDFN-EP | Higher profile and larger footprint; less suitable for ultra-thin portable designs | Select for legacy µMAX-compatible layouts or where thermal pad soldering is not feasible |
| MAX4717EBC-T+ | Same electrical specs; packaged in 12-bump UCSP (2.0mm × 1.5mm, 0.6mm height) | Smaller footprint and lower profile; requires specialized bump-soldering process and UCSP layout rules | Select for maximum board-area savings in space-constrained wearables or hearing aids |

FAQ
What is the maximum supply voltage rating for the MAX4717ETB+TG51?
The MAX4717ETB+TG51 has an absolute maximum supply voltage (V+) rating of +6.0V, but its specified operational range is +1.8V to +5.5V. Operating within this range ensures guaranteed RON, timing, and leakage performance per the datasheet. Exceeding +6.0V risks permanent damage due to internal ESD diode conduction.
Does the MAX4717ETB+TG51 support rail-to-rail analog signal switching?
Yes, the MAX4717ETB+TG51 supports rail-to-rail analog signal handling: the analog terminals (COM_, NO_, NC_) operate from 0V to V+, enabling full-swing signal routing without clipping. This capability is confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables for all supply voltages from +1.8V to +5.5V.
What is the guaranteed RON matching specification for the MAX4717ETB+TG51 at +3.0V supply?
The MAX4717ETB+TG51 guarantees ∆RON ≤ 0.3Ω between its two SPDT channels at +3.0V supply and +25°C, as specified in the Electrical Characteristics table under "On-Resistance Match Between Channels." This tight matching ensures balanced performance in differential applications such as USB D+/D− switching.
Can the digital control inputs (IN1/IN2) of the MAX4717ETB+TG51 accept 5V logic levels when V+ is 3.3V?
Yes, the MAX4717ETB+TG51 digital inputs tolerate up to +5.5V regardless of V+ supply voltage. When V+ = +3.3V, IN1 and IN2 accept 0V/5V logic levels - enabling direct interface with 5V microcontrollers or FPGAs without external level shifters, as explicitly stated in the Applications Information section.
Is the exposed thermal pad (EP) on the MAX4717ETB+TG51 package required to be connected to ground?
Yes, the exposed thermal pad (EP) on the MAX4717ETB+TG51 TDFN-EP package must be soldered to a PCB ground plane. This connection is essential for thermal dissipation (derating: 24.4mW/°C above +70°C) and EMI suppression. The datasheet specifies EP as "Exposed paddle (for TDFN package only). Connect to ground."
