Product details
Overview
MAX4723EUA 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 delivers 4.5Ω max on-resistance at +3V, <40ns turn-off time, and break-before-make timing of 1ns - enabling precise signal path control in battery-powered portable systems.
For engineers reviewing the MAX4723EUA datasheet, MAX4723EUA pinout, MAX4723EUA application, or MAX4723EUA equivalent, this device is selected for high-fidelity analog routing where rail-to-rail signal handling, sub-2ns differential skew, and <0.5nA leakage at +25°C are critical in space-constrained designs.
Technical Context
The MAX4723EUA implements a BiCMOS-based dual SPST architecture with independent digital control inputs (IN1, IN2) driving complementary NO/NC switch pairs. Its break-before-make operation ensures no signal shorting during state transitions, validated at 1ns delay under +2.7V to +3.6V supply conditions with 300Ω load and 35pF capacitance.
Signal integrity is maintained via 15pF on-channel capacitance, -55dB off-isolation at 10MHz, and -80dB crosstalk - all specified across -40°C to +85°C with full characterization at both +3V and +5V supplies. Logic inputs accept +1.8V–+5.5V levels regardless of V+, supporting mixed-voltage system interfacing.
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-level analog paths |
| Break-Before-Make Delay | 1ns - prevents momentary short-circuit between NO and NC paths during switching |
| Turn-Off Time (tOFF) | <40ns at +2.7V - enables fast signal gating in high-speed data acquisition |
| Off-Isolation | -55dB at 10MHz - suppresses unwanted coupling between inactive channels |
| On-Channel Capacitance | 15pF - preserves bandwidth and minimizes loading on high-frequency sources like USB 1.1 |
| Leakage Current (max) | ±1.5nA at TA = -40°C to +85°C - maintains accuracy in precision sample-and-hold circuits |
| Rail-to-Rail Signal Range | 0V to V+ - supports full-supply-swing analog signals without clipping or distortion |
Pinout & Package
MAX4723EUA is housed in an 8-pin µMAX package (3.05mm × 3.05mm × 1.1mm), compatible with standard surface-mount assembly processes and offering improved thermal performance over UCSP variants.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (V+) | Positive analog supply | Single +1.8V to +5.5V rail powers both analog and logic sections; requires 0.1µF bypass capacitor to GND |
| 2 (IN1) | Digital control input for COM1/NO1/NC1 | CMOS-compatible; accepts 0V/+V+ logic levels independent of V+ value |
| 3 (COM2) | Common terminal of second switch | Bidirectional analog node - connects to signal source or load depending on switch state |
| 4 (NC2) | Normally closed terminal of second switch | Connected to COM2 when IN2 = LOW; provides default signal path in fail-safe configurations |
| 5 (GND) | Digital/analog ground reference | Shared return for supply and logic; must be low-impedance to minimize noise coupling |
| 6 (IN2) | Digital control input for COM2/NC2 | Independent of IN1 - enables asynchronous control of dual switch channels |
| 7 (COM1) | Common terminal of first switch | Primary analog I/O node for channel 1; routed to NO1 or NC1 based on IN1 state |
| 8 (NO1) | Normally open terminal of first switch | Connects to COM1 only when IN1 = HIGH; used for active signal selection in multiplexing |
Key Features
| Feature | Design Value |
|---|---|
| USB 1.1 compliance | Guaranteed <2ns differential skew and <40ns tOFF at 12Mbps data rate - meets full-speed USB timing budgets |
| Low on-resistance flatness | 1.2Ω max variation over full analog range at +3V - ensures consistent gain and linearity across signal swing |
| Channel matching | 0.3Ω max RON mismatch between channels at +3V - critical for balanced differential signal routing |
| Rail-to-rail signal handling | Supports analog inputs from GND to V+ - eliminates need for level-shifting in single-supply systems |
| +1.8V logic compatibility | VIH = 1.4V / VIL = 0.5V at +3V supply - interfaces directly with low-voltage microcontrollers and FPGAs |

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 |
|---|---|---|---|
| MAX4721EUA | Two NO switches (vs. MAX4723EUA's NO+NC configuration); identical RON, timing, and package | Suitable for applications requiring dual active-high signal paths, not fail-safe default routing | Select MAX4721EUA when both channels must be open only on command - no default connection needed |
| MAX4722EUA | Two NC switches (vs. MAX4723EUA's NO+NC); same electrical specs and pinout except NC1/NC2 placement | Used where continuous signal path is required unless actively interrupted (e.g., safety interlocks) | Choose MAX4722EUA for always-connected architectures needing interrupt-on-demand capability |
Compared with MAX4721EUA and MAX4722EUA, the MAX4723EUA uniquely combines NO and NC functionality in one IC - enabling hybrid signal routing topologies (e.g., primary path + redundant backup) without board-level redesign or additional components.

FAQ
What is the maximum supply voltage rating for MAX4723EUA?
The MAX4723EUA supports a single positive supply from +1.8V to +5.5V. Absolute maximum rating is +6.0V on V+, but operation above +5.5V is not guaranteed and may cause permanent damage. At +5V supply, on-resistance drops to 3Ω max, improving conduction efficiency in higher-voltage systems.
Does MAX4723EUA support rail-to-rail analog signal switching?
Yes, MAX4723EUA fully supports rail-to-rail analog signal handling: input signals can swing from GND to V+ without degradation in on-resistance or distortion. This is confirmed across -40°C to +85°C and applies to both NO1/NC2 and COM1/COM2 terminals, enabling direct interfacing with single-supply op-amps and ADCs.
How does the break-before-make feature work in MAX4723EUA?
The MAX4723EUA guarantees a 1ns break-before-make interval between NO1 and NC2 during IN1 transitions, verified under +2.7V to +3.6V supply with 300Ω load and 35pF capacitance. This prevents momentary shorting in applications like relay replacement or signal path redundancy switching where cross-conduction must be avoided.
Can MAX4723EUA be used in USB 2.0 applications?
No, MAX4723EUA is specified and characterized only for USB 1.1 (12Mbps) compliance. Its >300MHz -3dB bandwidth and <2ns skew meet USB 1.1 requirements, but it lacks the signal integrity margin, impedance control, and ESD robustness required for USB 2.0 (480Mbps). For USB 2.0, consider dedicated high-speed switches like MAX14723.
What is the thermal performance difference between µMAX and UCSP packages for MAX4723EUA?
The MAX4723EUA in 8-pin µMAX offers 362mW continuous power dissipation at +70°C (derated 4.5mW/°C above), while the UCSP variant provides 379mW (derated 4.7mW/°C). The µMAX package uses conventional leadframe construction, delivering more predictable thermal resistance and easier reworkability compared to UCSP's wafer-level solder bumps, which require JEDEC-compliant IR/vapor-phase profiles.
