Product details
Overview
MAX4717EBC from Maxim Integrated is a dual SPDT analog switch IC designed for USB 1.1 signal routing and low-voltage audio switching. It features two 4.5Ω (max) low-RON switches with 1.2Ω flatness, 0.3Ω channel matching, <80ns tON, and rail-to-rail signal handling across +1.8V to +5.5V supply. Used in headphone switching and battery-operated portable devices.
For engineers reviewing the MAX4717EBC datasheet, MAX4717EBC pinout, MAX4717EBC application, or MAX4717EBC equivalent, key selection criteria include guaranteed break-before-make timing (1ns), 300MHz bandwidth, 15pF on-capacitance, USB 1.1 compliance (TID = 4000231), and UCSP-12 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4717EBC implements two independent SPDT analog switches using BiCMOS process technology, supporting bidirectional signal flow with rail-to-rail analog voltage range (0V to V+). Each switch exhibits low distortion (0.03% THD) and high off-isolation (–55dB at 10MHz), critical for maintaining signal integrity in mixed-signal USB and audio paths.
Its digital control inputs are +1.8V logic compatible with V+ = +2.7V to +3.6V, enabling interoperability with modern low-voltage microcontrollers. Break-before-make operation prevents momentary shorting during state transitions, while differential skew ≤2ns ensures matched timing between D+ and D– lines in USB 1.1 applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RON (max) | 4.5Ω per switch - enables low insertion loss & minimal voltage drop in 3.3V/5V signal paths |
| RON match (max) | 0.3Ω at +3.0V - ensures balanced channel performance for stereo audio or differential USB routing |
| Bandwidth | >300MHz - supports full-speed USB 1.1 (12Mbps) data without attenuation |
| tON/tOFF | <80ns / <40ns at +2.7V - allows fast multiplexing in real-time audio and data acquisition |
| On-capacitance | 15pF - minimizes loading on high-frequency signals and preserves edge integrity |
| Off-isolation | –55dB at 10MHz - suppresses crosstalk between active and inactive signal paths |
| Supply range | +1.8V to +5.5V - supports single-supply operation in battery-powered and legacy 5V systems |
Pinout & Package
Packaged in a 12-bump UCSP (chip-scale package) measuring 2.0mm × 1.50mm with 0.5mm bump pitch, the MAX4717EBC occupies minimal PCB area while delivering thermal and electrical performance comparable to larger packages.
| Pin/Terminal | Circuit Role | Design Meaning |

| A2 | IN2 | Digital control input for Switch 2 - CMOS-compatible, accepts 0V/+V+ logic levels |
| A3 | COM2 | Common terminal for Switch 2 - bidirectional I/O node for signal routing |
| A4 | NO2 | Analog Switch 2 Normally Open terminal - connects to COM2 when IN2 = high |
| B1 | GND | Ground reference - must be low-impedance for optimal noise rejection and THD performance |
| B4 | V+ | Positive supply input - powers both analog and digital sections; decoupling required near pin |
| C1 | NC1 | Analog Switch 1 Normally Closed terminal - connects to COM1 when IN1 = low |
| C2 | IN1 | Digital control input for Switch 1 - independent of IN2; enables asynchronous switching |
| C3 | COM1 | Common terminal for Switch 1 - shared path for two analog signal options (NO1/NC1) |
| C4 | NO1 | Analog Switch 1 Normally Open terminal - connects to COM1 when IN1 = high |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4717ETB | Same electrical specs; packaged in 10-pin TDFN (3×3×0.8mm) with exposed pad | Better thermal dissipation (1951mW PD) and higher ESD rating; requires different footprint | Select for higher power or thermal-limited designs where UCSP reflow constraints exist |
| MAX4717EUB | Identical functionality; housed in 10-pin µMAX (3×3mm) with gull-wing leads | Easier prototyping and manual soldering; lower frequency response margin due to lead inductance | Choose for lab validation, low-volume production, or legacy board compatibility |
Compared with MAX4717ETB and MAX4717EUB, the MAX4717EBC offers the smallest PCB footprint (2.0mm × 1.50mm) and lowest parasitic capacitance, making it optimal for ultra-compact USB/audio modules where layout density and signal fidelity are prioritized over thermal headroom or assembly simplicity.

FAQ
What is the maximum operating temperature range for the MAX4717EBC?
The MAX4717EBC is specified for operation from 0°C to +70°C, as confirmed in the Ordering Information table. This commercial-grade temperature range aligns with its UCSP packaging and target applications in consumer portable electronics, distinguishing it from industrial-grade variants like MAX4717EUB (–40°C to +85°C).
Does the MAX4717EBC support rail-to-rail analog signal switching?
Yes, the MAX4717EBC supports rail-to-rail analog signal handling - its analog terminals (COM_, NO_, NC_) operate from 0V to V+, enabling full-swing signal routing without clipping. This is explicitly stated in the Absolute Maximum Ratings and Electrical Characteristics tables for both +3V and +5V supplies.
Is the MAX4717EBC pin-compatible with other MAX4717 package variants?
No - the MAX4717EBC uses a 12-bump UCSP package with a 4×3 bump array, while MAX4717ETB (TDFN) and MAX4717EUB (µMAX) use 10-pin footprints with different pin counts, layouts, and terminal assignments. Pin mapping differs significantly; PCB redesign is required for substitution.
What is the typical on-resistance flatness of the MAX4717EBC at +3.0V supply?
The MAX4717EBC exhibits 1.2Ω (max) on-resistance flatness at +3.0V supply, defined as the difference between maximum and minimum RON over the full analog signal range (0V to V+). This value is guaranteed across temperature and ensures consistent gain and linearity in precision signal paths.
Can the MAX4717EBC be used in USB 2.0 applications?
No - the MAX4717EBC is specified for USB 1.1 compliance (TID = 4000231) and has a >300MHz bandwidth, which is insufficient for USB 2.0's 480Mbps (240MHz fundamental). Its 15pF on-capacitance and 4.5Ω RON also introduce excessive insertion loss and jitter at high speeds; dedicated USB 2.0 switches (e.g., MAX3355) are required.
