Product details
Overview
MAX4717ETB+TG47 from Maxim Integrated is a dual SPDT analog switch optimized for USB 1.1 and low-voltage audio signal routing. It features two 4.5Ω (max) RON switches with 1.2Ω flatness, 0.3Ω channel matching, <80ns tON, and rail-to-rail signal handling up to +5.5V - deployed in portable audio switching and battery-powered USB interface circuits.
For engineers reviewing the MAX4717ETB+TG47 datasheet, MAX4717ETB+TG47 pinout, MAX4717ETB+TG47 application, or MAX4717ETB+TG47 equivalent, key selection criteria include guaranteed break-before-make timing (1ns), 300MHz bandwidth, low 15pF on-capacitance, ±100mA continuous current rating, and UCSP-10/TDFN-10 package compatibility for space-constrained designs.
Technical Context
The MAX4717ETB+TG47 implements two independent SPDT analog switches using BiCMOS process technology, each with complementary control logic (IN1/IN2) enabling break-before-make operation. Its low RON and flatness are maintained across +1.8V to +5.5V supply range, supporting bidirectional signal flow without polarity constraints.
It delivers <2ns differential skew between channels and supports rail-to-rail analog signals from GND to V+, while digital inputs tolerate up to +5.5V regardless of V+ level - enabling mixed-voltage system interfacing. Charge injection is limited to 5pC, critical for precision sample-and-hold and low-distortion audio paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RON (max) | 4.5Ω per SPDT channel at +2.7V - ensures minimal voltage drop and signal attenuation in USB D+/D− and headphone paths. |
| RON flatness (max) | 1.2Ω over full analog range - preserves linearity and THD <0.03% in audio routing applications. |
| tON/tOFF | <80ns / <40ns at +2.7V - enables clean 12Mbps USB 1.1 data switching with minimal intersymbol interference. |
| Bandwidth | >300MHz - supports high-fidelity analog video and wideband RF signal routing without roll-off. |
| On-capacitance | 15pF - minimizes loading on high-impedance sources and maintains signal integrity in fast-switching nodes. |
| Off-isolation | –55dB at 10MHz - suppresses crosstalk between active and inactive channels in multi-source A/V systems. |
| Supply range | +1.8V to +5.5V single supply - simplifies power architecture in mixed-voltage portable electronics. |
Pinout & Package
MAX4717ETB+TG47 is packaged in a 10-pin TDFN-EP (3mm × 3mm, 0.8mm height) with exposed thermal pad. Pinout follows standard analog switch topology with dual independent SPDT sections, each featuring COM/NO/NC terminals and dedicated digital control inputs.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply input - must be applied before analog signals to prevent latch-up; supports 1.8V–5.5V operation. |
| 2 | NO1 | Analog Switch 1 Normally Open terminal - connects to COM1 when IN1 = high; used for primary signal path selection. |
| 3 | COM1 | Analog Switch 1 Common terminal - bidirectional I/O node; routes signal between NO1 and NC1 based on IN1 state. |
| 4 | IN1 | Digital control input for Switch 1 - CMOS-compatible; VIH = 1.4V (at +2.7V), tolerates up to +5.5V logic levels. |
| 5 | NC1 | Analog Switch 1 Normally Closed terminal - connects to COM1 when IN1 = low; provides alternate signal path. |
| 6 | GND | Ground reference - must be low-impedance; exposed paddle (Pin EP) requires solder connection to PCB ground plane. |
| 7 | NC2 | Analog Switch 2 Normally Closed terminal - independent of Switch 1; enables dual-path routing without shared logic. |
| 8 | IN2 | Digital control input for Switch 2 - asynchronous with IN1; allows independent control of second SPDT section. |
| 9 | COM2 | Analog Switch 2 Common terminal - bidirectional node; supports stereo headphone switching or dual USB lanes. |
| 10 | NO2 | Analog Switch 2 Normally Open terminal - completes second SPDT path; enables simultaneous dual-channel routing. |
Key Features
| Feature | Design Value |
|---|---|
| USB 1.1 compliance (TID #4000231) | Guaranteed ≤2ns differential skew and 12Mbps data rate support - meets USB-IF electrical requirements for host/peripheral switching. |
| Rail-to-rail analog signal handling | Full GND-to-V+ range supported - eliminates level-shifting circuitry in battery-powered audio and sensor interfaces. |
| Break-before-make switching | 1ns minimum delay prevents momentary short-circuit between NO and NC paths - critical for avoiding signal glitches in audio/video routing. |
| Low 15pF on-channel capacitance | Minimizes capacitive loading on high-impedance sources (e.g., MEMS microphones, op-amp outputs) and preserves bandwidth. |
| 0.3Ω RON match between channels | Ensures balanced signal transfer in stereo or differential applications - reduces channel imbalance in headphone amplifiers. |
| +1.8V logic compatibility | Accepts 1.4V VIH at +2.7V supply - interoperable with modern low-voltage microcontrollers and baseband processors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4718ETB+ | Features one 4.5Ω SPDT and one 20Ω SPDT - higher RON on second channel limits current handling to ±50mA. | Better suited for mixed-signal routing where one path carries high-precision analog and the other handles lower-bandwidth control signals. | Select MAX4718ETB+ only when asymmetric RON is required; MAX4717ETB+TG47 provides matched performance for dual-channel symmetry. |
| ADG774AACPZ-REEL7 | Quad SPST, 2.6Ω RON, but no break-before-make guarantee and 150MHz bandwidth - lacks USB 1.1 skew certification. | Applicable in general-purpose low-voltage multiplexing, but not validated for USB data integrity or high-fidelity audio. | Use ADG774A only in non-USB, non-audio contexts where ultra-low RON outweighs timing and isolation requirements. |
Compared with MAX4718ETB+, MAX4717ETB+TG47 delivers symmetric dual 4.5Ω SPDT performance ideal for stereo or differential routing; versus ADG774AACPZ-REEL7, it provides certified USB timing, higher bandwidth, and guaranteed break-before-make - essential for robust data and audio switching.

FAQ
What is the maximum supply voltage rating for MAX4717ETB+TG47?
The MAX4717ETB+TG47 has an absolute maximum supply voltage (V+) rating of +6.0V, but its specified operational range is +1.8V to +5.5V. Operating beyond +5.5V risks permanent damage and invalidates parametric guarantees. For reliable long-term use, maintain V+ within the 1.8V–5.5V range as defined in the electrical characteristics tables.
Does MAX4717ETB+TG47 support break-before-make switching, and what is the guaranteed delay?
Yes, MAX4717ETB+TG47 guarantees break-before-make operation with a minimum time delay of 1ns between opening one path and closing the other. This is measured under standard test conditions (VNO/VNC = 1.5V, RL = 300Ω, CL = 35pF) and ensures no signal shorting during state transitions - critical for glitch-free USB and audio switching.
Can MAX4717ETB+TG47 handle analog signals beyond the supply rails?
No, MAX4717ETB+TG47 does not support overvoltage analog signals. The absolute maximum rating for COM_, NO_, and NC_ pins is (V+ + 0.3V) and –0.3V. Exceeding these clamps internal diodes and may cause excessive current flow. Analog signals must remain strictly within 0V to V+ to ensure proper operation and reliability.
What is the thermal pad (EP) connection requirement for MAX4717ETB+TG47?
The exposed thermal pad (EP) on the MAX4717ETB+TG47 TDFN package must be soldered directly to a PCB ground plane. It is electrically connected to GND internally and serves both thermal dissipation and EMI reduction functions. Failure to connect EP results in elevated junction temperature and potential parametric shift or reliability degradation.
Is MAX4717ETB+TG47 compatible with +1.8V logic-level microcontrollers?
Yes, MAX4717ETB+TG47 accepts +1.8V logic inputs: at +2.7V supply, VIH is specified at +1.4V (min) and VIL at +0.5V (max), making it fully compatible with 1.8V CMOS outputs. Input leakage remains below ±100nA, ensuring minimal loading on low-power GPIOs in battery-operated systems.
