Product details
Overview
MAX4753EGE+ from Maxim Integrated is a quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, operating from a single +1.6V to +3.6V supply. It delivers 0.9Ω max on-resistance at +3V, 30ns turn-on time, break-before-make switching, and 1.8V CMOS logic compatibility - enabling precise signal routing in low-voltage portable audio and data-acquisition systems.
For engineers reviewing the MAX4753EGE+ datasheet, MAX4753EGE+ pinout, MAX4753EGE+ application, or MAX4753EGE+ equivalent, this page provides verified electrical parameters, QFN-EP package details, truth table behavior for mixed NO/NC configuration, and real-world selection guidance against functionally comparable analog switches.
Technical Context
The MAX4753EGE+ implements CMOS-based transmission-gate architecture optimized for rail-to-rail analog signal handling across its full +1.6V to +3.6V supply range. Its break-before-make timing (2ns min) prevents momentary shorting between NO and NC paths during state transitions, critical for power routing and battery-switching applications.
Each of its four independent SPST switches supports bidirectional signal flow, ±100mA continuous current, and maintains <0.1Ω on-resistance flatness over the entire analog input range - ensuring minimal distortion in audio and sensor signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 0.9Ω max at +3V supply - enables low-loss switching of analog signals up to 100mA without significant voltage drop. |
| On-Resistance Flatness | 0.1Ω max at +3V - ensures consistent gain and linearity across full signal swing (GND to V+). |
| RON Matching | 0.12Ω max at +3V - guarantees matched channel performance for differential or multi-path signal routing. |
| Turn-On / Turn-Off Time | tON = 30ns, tOFF = 25ns (RL = 50Ω, CL = 35pF) - supports high-speed multiplexing in data-acquisition and communications circuits. |
| Break-Before-Make Delay | tBBM = 2ns min - eliminates transient conduction between NO and NC terminals during switching. |
| Supply Voltage Range | +1.6V to +3.6V single supply - compatible with Li-ion, coin-cell, and low-power MCU I/O domains. |
| Logic Compatibility | 1.8V CMOS inputs at +3V supply - interfaces directly with modern low-voltage microcontrollers without level shifters. |
Pinout & Package
MAX4753EGE+ is housed in a 3mm × 3mm, 16-pin QFN-EP package with exposed pad (EP) requiring connection to GND for thermal and electrical performance. Pin numbering follows standard QFN top-view orientation (pin 1 marked by dot or chamfer).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 11, 15 | NO1, NO3, COM1, COM3 | Pins 1 (NO1), 7 (COM1), 11 (NO3), 15 (COM3) form first NO/COM pair and third NO/COM pair - used for active-high signal path selection. |
| 3, 6, 10, 14 | NC2, NC4, COM2, COM4 | Pins 3 (NC2), 6 (COM2), 10 (NC4), 14 (COM4) form second NC/COM and fourth NC/COM pairs - provide default-closed paths activated by logic low. |
| 2, 4, 8, 9 | IN1, IN2, IN3, IN4 | Independent CMOS-compatible control inputs - drive respective switches; high = NO closed / NC open, low = NO open / NC closed. |
| 12, 13, 16 | GND, V+, EP | Pins 12 (GND), 13 (V+), 16 (EP) - EP must be soldered to PCB ground plane for thermal dissipation and noise immunity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4753EUD+ | Same die, 14-pin TSSOP package - no exposed pad, higher thermal resistance (9.1W/°C derating vs. 16.9W/°C for QFN). | Suitable for prototyping or lower-power applications where board space permits larger footprint and thermal performance is less critical. | Select MAX4753EUD+ when TSSOP assembly infrastructure exists and thermal load is <300mW. |
| TMUX1574RTER | TI part with 0.5Ω RON (typ), but no break-before-make; requires ≥1.08V logic high threshold at 1.8V supply vs. MAX4753EGE+'s 1.4V. | Offers lower RON but lacks guaranteed tBBM - unsuitable where power path shorting must be avoided. | Choose TMUX1574RTER only if break-before-make is not required and tighter RON tolerance is prioritized over safety-critical isolation. |
Compared with MAX4753EUD+, the MAX4753EGE+ delivers superior thermal management and smaller footprint; versus TMUX1574RTER, it provides deterministic break-before-make timing essential for power routing - making MAX4753EGE+ the preferred choice for battery-switching and fail-safe signal path control.

FAQ
What is the maximum continuous current rating for MAX4753EGE+?
The MAX4753EGE+ supports ±100mA continuous current per channel (COM_, NO_, or NC_ terminal). This rating applies across the full operating temperature range (–40°C to +85°C) and supply voltage range (+1.6V to +3.6V), enabling reliable use in power routing and sensor interface applications without derating under typical conditions.
Does MAX4753EGE+ support rail-to-rail analog signal switching?
Yes, MAX4753EGE+ supports rail-to-rail analog signal switching from GND to V+. When powered from a +3V supply, it passes signals across the full 0V to +3V range with minimal on-resistance variation (<0.1Ω flatness), preserving signal integrity in audio, sensor, and data-acquisition paths without external biasing.
Is break-before-make timing guaranteed for MAX4753EGE+?
Yes, break-before-make timing is a guaranteed feature of MAX4753EGE+: tBBM ≥ 2ns (minimum) is specified in the Electrical Characteristics table for the MAX4753 variant. This ensures no overlap between NO and NC conduction states during switching - a key requirement for safe power domain selection and fault-tolerant signal routing.
What is the recommended PCB layout practice for the exposed pad on MAX4753EGE+?
The exposed pad (EP) on MAX4753EGE+ must be soldered to a solid PCB ground plane. Use at least 4 thermal vias (0.3mm diameter) connecting EP to an internal or bottom-layer ground plane. This ensures optimal thermal dissipation (1349mW max power dissipation at TA = +70°C) and reduces ground bounce during fast switching transitions.
Can MAX4753EGE+ operate with a 1.8V supply, and what are the key trade-offs?
Yes, MAX4753EGE+ operates from +1.6V to +3.6V. At +1.8V supply, RON increases to 2.5Ω (max), tON/tOFF extend to 35ns/30ns, and VIH drops to +1.0V. These shifts are fully characterized in the +1.8V Electrical Characteristics table - enabling use in ultra-low-power modes while maintaining functional compatibility with 1.8V logic systems.
