Product details
Overview
MAX4722EBL+T from Maxim Integrated is a dual single-pole/single-throw (SPST) analog switch with two normally closed (NC) channels, operating from +1.8V to +5.5V supply. It delivers 4.5Ω max on-resistance at +3V, <0.5nA leakage at +25°C, and 300MHz -3dB bandwidth-designed specifically for USB 1.1 signal routing and low-voltage audio switching in space-constrained portable systems.
For engineers reviewing the MAX4722EBL+T datasheet, MAX4722EBL+T pinout, MAX4722EBL+T application, or MAX4722EBL+T equivalent, this page provides verified electrical specs, UCSP-9 package layout, real-world USB/audio use cases, and validated alternative parts for signal integrity–critical analog switching designs.
Technical Context
The MAX4722EBL+T implements a BiCMOS-based dual NC-switch architecture with break-before-make timing (1ns), rail-to-rail analog signal handling (0V to V+), and +1.8V logic-compatible digital inputs-even when powered from +2.7V to +3.6V. Its 15pF on-channel capacitance and <2ns differential skew preserve high-speed USB 1.1 (12Mbps) signal fidelity.
It guarantees operation across –40°C to +85°C, supports bidirectional analog paths, and features matched RON (≤0.3Ω) and flatness (≤1.2Ω) at +3V-enabling precise channel-to-channel signal consistency in audio multiplexing and data-acquisition front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 4.5Ω at +3V supply - ensures minimal voltage drop and power loss in low-voltage signal paths |
| RON Matching (max) | 0.3Ω between channels at +3V - enables accurate differential or stereo signal routing without gain mismatch |
| -3dB Bandwidth | >300MHz - supports full-speed USB 1.1 (12Mbps) and wideband audio without attenuation |
| Off-Isolation | -55dB at 10MHz - suppresses crosstalk between active and inactive signal paths in dense PCB layouts |
| Leakage Current (max) | ±1.5nA at +85°C - maintains signal integrity in battery-powered sample-and-hold or sensor interfaces |
| Turn-On/Off Time | <80ns / <40ns at +2.7V - enables fast channel switching in time-multiplexed data acquisition |
| Analog Signal Range | 0V to V+ - allows rail-to-rail input/output swing without clipping in single-supply systems |
Pinout & Package
MAX4722EBL+T uses a 9-bump wafer-level chip-scale package (UCSP™), measuring 1.52mm × 1.52mm with 0.5mm bump pitch. The package requires JEDEC J-STD-020A-compliant reflow profiles and prohibits hand/wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4722EUA+ | Same electrical specs but in 8-pin µMAX package (3.05mm × 3.05mm); no bump-solder constraints | Better suited for prototyping or legacy PCBs not designed for UCSP reflow profiles | Select MAX4722EUA+ when board assembly lacks JEDEC J-STD-020A-compliant reflow capability |
| TMUX1574RSVR | 4.8Ω RON (max), 1.8V–5.5V supply, but only 100MHz bandwidth and no guaranteed USB 1.1 skew spec | Limited to lower-speed audio or general-purpose muxing-not validated for USB full-speed signaling | Choose TMUX1574RSVR only if bandwidth demand is <100MHz and USB compliance is not required |
Compared with MAX4722EUA+ and TMUX1574RSVR, the MAX4722EBL+T uniquely combines UCSP-9 footprint efficiency, USB 1.1–guaranteed skew performance, and production-ready reliability for high-density portable electronics-making it irreplaceable where space, speed, and standard compliance intersect.

FAQ
What is the maximum supply voltage rating for MAX4722EBL+T?
The MAX4722EBL+T supports a continuous supply voltage range of +1.8V to +5.5V, with absolute maximum rating of +6.0V on V+. Operation beyond +5.5V risks permanent damage per the Absolute Maximum Ratings table, and all electrical specifications are guaranteed only within the +1.8V to +5.5V operating range. The MAX4722EBL+T must not be operated at 6.0V in functional designs.
Does MAX4722EBL+T support bidirectional analog signal flow?
Yes, the MAX4722EBL+T supports fully bidirectional analog signal routing on all NC and COM pins-meaning either NC1/NC2 or COM1/COM2 can serve as input or output depending on system topology. This is explicitly confirmed in the Applications Information section and enabled by its CMOS transmission-gate architecture. Signal direction has no impact on RON, bandwidth, or leakage performance in the MAX4722EBL+T.
What is the logic polarity of the control inputs on MAX4722EBL+T?
The MAX4722EBL+T uses active-low logic: IN1 and IN2 must be driven LOW (≤0.5V at +3V supply) to close the respective NC switches (connecting NC1↔COM1 or NC2↔COM2), and HIGH (≥1.4V at +3V supply) to open them. This is defined in the Truth Tables and Pin Configurations section and applies identically across all temperature and supply conditions for the MAX4722EBL+T.
Can MAX4722EBL+T be used in USB 2.0 applications?
No, the MAX4722EBL+T is specified and tested only for USB 1.1 (12Mbps) compliance. Its >300MHz bandwidth and <2ns skew meet USB 1.1 requirements but do not guarantee signal integrity at USB 2.0's 480Mbps data rate, which demands significantly higher bandwidth, lower capacitance, and tighter impedance control. The MAX4722EBL+T datasheet makes no claims regarding USB 2.0 functionality.
What is the thermal profile requirement for soldering MAX4722EBL+T?
The MAX4722EBL+T UCSP-9 package requires strict adherence to JEDEC J-STD-020A, paragraph 7.6, Table 3 for infrared/vapor-phase reflow-specifically peak bump temperature ≤220°C (IR) or ≤215°C (vapor phase), with preheating mandatory. Hand soldering and wave soldering are explicitly prohibited per the UCSP Reliability notice, and deviation risks die attach failure or interconnect fracture in the MAX4722EBL+T.
