Product details
Overview
MAX4723EUA+T from Maxim Integrated is a dual single-pole/single-throw (SPST) analog switch with one normally open (NO) and one normally closed (NC) channel, designed for USB 1.1 signal routing and low-voltage audio switching. It operates from a single +1.8V to +5.5V supply, delivers 4.5Ω max on-resistance at +3V, supports rail-to-rail analog signal handling, and features break-before-make timing of 1ns - enabling precise signal path control in portable instrumentation and interface circuits.
For engineers reviewing the MAX4723EUA+T datasheet, MAX4723EUA+T pinout, MAX4723EUA+T application, or MAX4723EUA+T equivalent, this page provides verified electrical parameters, µMAX package layout, USB-compliant timing behavior, leakage performance below ±0.5nA at +25°C, and validated alternative options for dual SPST switching with mixed NO/NC topology.
Technical Context
The MAX4723EUA+T implements a BiCMOS analog switch architecture optimized for low-voltage bidirectional signal routing. Its dual-channel configuration integrates independent logic-controlled NO and NC paths, each with guaranteed 1ns break-before-make timing and <2ns differential skew - critical for maintaining signal integrity in full-speed USB (12Mbps) data paths.
It supports rail-to-rail analog input/output swing (0V to V+), exhibits 15pF on-channel capacitance and <0.5nA leakage at +25°C, and maintains stable RON flatness (≤1.2Ω max) across the full analog range - enabling accurate sampling and minimal distortion in audio and data-acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V single supply - enables direct integration into 1.8V, 3.3V, and 5V systems without level-shifting. |
| Max On-Resistance (V+ = +3V) | 4.5Ω - ensures minimal voltage drop and power loss in low-level analog signal paths. |
| RON Matching (V+ = +3V) | 0.3Ω max - guarantees consistent gain and signal balance between NO and NC channels. |
| Break-Before-Make Delay | 1ns - prevents momentary short-circuit during channel switching in multiplexed signal routing. |
| Off-Isolation @ 10MHz | -55dB - suppresses crosstalk between active and inactive signal paths in high-frequency applications. |
| On-Channel Capacitance | 15pF - preserves bandwidth (>300MHz -3dB) and minimizes loading on high-speed sources. |
| Leakage Current (TA = +25°C) | <±0.5nA - avoids DC error accumulation in precision sample-and-hold or sensor front-end circuits. |
Pinout & Package
MAX4723EUA+T is housed in an 8-pin µMAX package (3.05mm × 3.05mm × 1.02mm), featuring exposed pad thermal enhancement and industry-standard pin spacing (0.65mm pitch). The package is RoHS-compliant and compatible with standard reflow soldering profiles.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive analog supply input - must be bypassed with 0.1µF capacitor to GND for noise immunity. |
| 2 | IN1 | Digital control input for COM1–NO1 switch - accepts +1.8V logic with VIH = 1.4V (at +3V supply). |
| 3 | COM2 | Common terminal for second switch - bidirectional analog node shared between NC2 and NO1 paths. |
| 4 | NC2 | Normally closed analog terminal for second switch - conducts when IN2 = LOW. |
| 5 | GND | Digital/analog ground reference - requires low-impedance connection to system ground plane. |
| 6 | IN2 | Digital control input for COM2–NC2 switch - logic-compatible with mixed-voltage systems up to +5.5V. |
| 7 | COM1 | Common terminal for first switch - bidirectional analog node shared between NO1 and NC1 paths. |
| 8 | NO1 | Normally open analog terminal for first switch - conducts only when IN1 = HIGH. |
Key Features
| Feature | Design Value |
|---|---|
| Mixed NO/NC dual-channel topology | Enables flexible signal routing - e.g., default-path continuity (NC) with override capability (NO) in fail-safe interfaces. |
| USB 1.1 compliance | Guaranteed <2ns skew and <80ns tON at +2.7V support reliable 12Mbps data switching without packet corruption. |
| Rail-to-rail analog operation | Supports full 0V to V+ signal swing - eliminates clipping in audio line drivers and battery-powered sensor interfaces. |
| Low 15pF on-capacitance | Maintains >300MHz bandwidth and reduces capacitive loading on high-Z sources like op-amp outputs or crystal filters. |
| +1.8V logic compatibility | Accepts 1.4V VIH at +3V supply - allows direct interfacing with low-voltage microcontrollers without external translators. |
Applications
| USB Peripheral Switching | Audio Signal Multiplexing |
|---|---|
|

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 |
|---|---|---|---|
| MAX4721EUA+T | Two NO switches (vs. MAX4723's NO+NC); identical RON, timing, and supply specs. | Suitable where both paths require active-enable behavior - not for default-on/fail-safe configurations. | Select when circuit requires dual normally-open routing without NC functionality. |
| MAX4722EUA+T | Two NC switches (vs. MAX4723's NO+NC); same electrical performance and package. | Used where continuous conduction is required unless actively interrupted - e.g., safety interlock paths. | Choose when default-closed operation is mandatory for system-level fault tolerance. |
Compared with MAX4721EUA+T and MAX4722EUA+T, the MAX4723EUA+T uniquely provides mixed NO/NC topology in the same footprint - enabling single-device implementation of redundant signal paths, hot-swap arbitration, or fail-safe bypass architectures without redesigning PCB layout.

FAQ
What is the maximum operating supply voltage for MAX4723EUA+T?
The MAX4723EUA+T supports a single-supply range from +1.8V to +5.5V. Absolute maximum rating for V+ is +6.0V, but functional operation is specified only up to +5.5V. Operation beyond this voltage risks permanent damage and violates the device's guaranteed specifications, including RON, leakage, and timing parameters.
Does MAX4723EUA+T support rail-to-rail analog signal switching?
Yes, the MAX4723EUA+T supports true rail-to-rail analog signal handling - signals from 0V to V+ pass through the switch with minimal distortion or gain error. This is enabled by its BiCMOS process and internal level-shifting design, making it suitable for audio line drivers and sensor interfaces where full dynamic range utilization is required.
What is the function of the NC2 pin on MAX4723EUA+T?
The NC2 pin on MAX4723EUA+T is the normally closed terminal for the second switch channel (COM2–NC2). It conducts to COM2 when IN2 is logic LOW and opens when IN2 is HIGH. This provides default-path continuity - useful in fail-safe designs, such as maintaining audio output during microcontroller reset or power-up sequencing.
Can MAX4723EUA+T be used in USB 2.0 applications?
No, the MAX4723EUA+T is specified and characterized for USB 1.1 (12Mbps) operation only. Its >300MHz bandwidth and <2ns skew meet USB 1.1 requirements, but it lacks the signal integrity margin, ESD robustness, and impedance control needed for USB 2.0 high-speed (480Mbps) signaling. For USB 2.0, dedicated high-speed switches like the MAX14512 should be considered instead of MAX4723EUA+T.
What is the thermal resistance (θJA) of the MAX4723EUA+T in the µMAX package?
The MAX4723EUA+T in the 8-pin µMAX package has a junction-to-ambient thermal resistance (θJA) of 220°C/W under standard JEDEC 51-7 conditions (single-layer 1-in² copper pad). Derating begins above +70°C ambient at 4.5mW/°C, limiting max continuous power dissipation to 362mW at +70°C - a key constraint in enclosed or high-temperature environments.
