Product details
Overview
The MAX4722EBL+ 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, <40ns turn-off time at +2.7V, and 15pF on-channel capacitance - optimized for USB 1.1 signal routing and low-voltage audio switching in portable equipment.
For engineers reviewing the MAX4722EBL+ datasheet, MAX4722EBL+ pinout, MAX4722EBL+ application, or MAX4722EBL+ equivalent, this page provides verified electrical specs, UCSP-9 package layout, rail-to-rail signal handling capability, and direct alternatives for USB/audio analog switching designs.
Technical Context
The MAX4722EBL+ implements BiCMOS-switch architecture enabling break-before-make operation (1ns), <2ns differential skew, and guaranteed performance across -40°C to +85°C. Its dual NC configuration ensures default-closed signal paths when control inputs are inactive.
It supports rail-to-rail analog signals (0V to V+), features +1.8V logic-compatible digital inputs (VIH = 1.4V at +3V supply), and maintains <0.5nA leakage at +25°C - critical for battery-operated systems requiring ultra-low standby current.
Key Specifications

| On-Resistance Matching | 0.3Ω max between channels - preserves signal balance in dual-path applications |
| Turn-Off Time | <40ns at +2.7V - enables fast channel isolation for high-speed USB 1.1 (12Mbps) data |
| On-Channel Capacitance | 15pF - minimizes loading and preserves bandwidth in audio and RF-sensitive circuits |
| Off-Isolation | -55dB at 10MHz - suppresses crosstalk between active and inactive signal paths |
| Supply Range | +1.8V to +5.5V - supports direct integration with Li-ion, 3.3V, and 5V system rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4722EUA+ | Same electrical specs but in 8-pin µMAX package (3.05mm × 3.05mm); no UCSP thermal/space advantages | Suitable for prototyping or legacy layouts where UCSP assembly is unavailable | Select when board-level reflow capability for chip-scale packages is limited |
| TMUX1574RTER | 4.2Ω RON (typ), 12pF CON, but requires ≥2.5V supply; not rated for 1.8V operation | Optimized for industrial 3.3V/5V systems; lacks USB 1.1 timing validation | Choose for higher bandwidth (>500MHz) needs where 1.8V operation is unnecessary |
Compared with MAX4722EBL+, the MAX4722EUA+ offers identical functionality in a larger package ideal for hand-soldered prototypes, while TMUX1574RTER trades 1.8V compatibility for marginally lower capacitance - making MAX4722EBL+ the only option meeting USB 1.1 timing and ultra-low-voltage requirements in space-constrained designs.

FAQ
What is the maximum supply voltage rating for the MAX4722EBL+?
The MAX4722EBL+ has an absolute maximum supply voltage (V+) of +6.0V, but its specified operational range is +1.8V to +5.5V. Operation beyond +5.5V risks permanent damage per Absolute Maximum Ratings. The device is fully characterized at +3V and +5V, delivering 4.5Ω and 3Ω max RON respectively - confirming robust performance across its entire rated supply range. Always observe the 0.3V clamp limit on analog pins relative to GND and V+.
Does the MAX4722EBL+ support rail-to-rail analog signal operation?
Yes, the MAX4722EBL+ supports true rail-to-rail analog signal handling: analog voltages from 0V to V+ pass through the NC switches with minimal RON variation (<1.2Ω flatness at +3V). This is confirmed in the Typical Operating Characteristics plots showing RON vs. VCOM across the full supply range. The feature enables direct interfacing with op-amps, ADCs, and sensors operating at supply rails without signal clipping or distortion.
What is the function of the NC1 and NC2 pins on the MAX4722EBL+?
The NC1 and NC2 pins on the MAX4722EBL+ are the normally closed analog terminals of its two independent SPST switches. When the corresponding digital control inputs (IN1 and IN2) are logic low, NC1 connects to COM1 and NC2 connects to COM2. When IN1 or IN2 goes high, that switch opens. This NC configuration provides fail-safe connectivity - critical in applications like USB port selection where default connection prevents floating signal lines during boot or fault conditions.
Can the MAX4722EBL+ be used in USB 2.0 applications?
No, the MAX4722EBL+ is specified and validated only for USB 1.1 (12Mbps) operation. Its >300MHz -3dB bandwidth and <2ns skew meet USB 1.1 signal integrity requirements, but it lacks the >480Mbps timing margins, lower RON (<2Ω), and enhanced ESD protection required for USB 2.0 High-Speed mode. Using MAX4722EBL+ in USB 2.0 designs may result in signal degradation, packet errors, or non-compliance - select USB 2.0–rated switches like MAX14533 for such applications.
What is the recommended power-supply bypassing for the MAX4722EBL+?
A 0.1µF ceramic capacitor placed as close as possible between the V+ (C2) and GND (A2) pins is the recommended bypass for the MAX4722EBL+. This minimizes high-frequency switching noise coupling into the analog signal path and improves noise margin for digital control inputs. The datasheet confirms this value is adequate for most applications; for high-density layouts or noisy environments, adding a 1µF bulk capacitor nearby further stabilizes the supply rail without degrading transient response.
