Product details
Overview
MAX4753EUD+ from Maxim Integrated is a low-voltage, quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, 0.9Ω max on-resistance at +3V supply, break-before-make switching action, and 1.8V CMOS logic compatibility. It operates from a single +1.6V to +3.6V supply and supports rail-to-rail analog signal routing in portable audio multiplexing and battery-powered data-acquisition systems.
For engineers reviewing the MAX4753EUD+ datasheet, MAX4753EUD+ pinout, MAX4753EUD+ application, or MAX4753EUD+ equivalent, key selection criteria include verified break-before-make timing (2ns), RON matching (0.12Ω max), off-isolation (–65dB at 1MHz), and TSSOP-14 package compatibility with space-constrained handheld designs.
Technical Context
The MAX4753EUD+ implements CMOS-based quad SPST switching with independent control of two NO and two NC paths. Its break-before-make architecture prevents momentary shorting during channel transitions, critical for power routing and signal integrity in mixed-signal systems.
It features rail-to-rail analog signal handling (0V to V+), 30ns turn-on/25ns turn-off times at +3V, and ultra-low quiescent current (<1µW), enabling use in always-on subsystems without compromising battery life.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 0.9Ω max at +3V - enables <100mV drop at 100mA load, preserving signal fidelity in low-voltage precision paths |
| RON Matching | 0.12Ω max at +3V - ensures consistent gain/attenuation across channels in multi-path audio or sensor routing |
| Break-Before-Make Time | 2ns guaranteed - eliminates cross-conduction risk when switching between power domains or signal sources |
| Turn-On / Turn-Off Time | 30ns / 25ns at +3V - supports >10MHz digital control rates and high-speed multiplexed sampling |
| Off-Isolation | –65dB at 1MHz - suppresses crosstalk between inactive channels in dense PCB layouts |
| Supply Range | +1.6V to +3.6V - compatible with Li-ion, Li-poly, and dual-cell alkaline battery systems without regulation |
| Logic Compatibility | 1.8V CMOS input threshold at +3V supply - interoperable with modern low-voltage microcontrollers and FPGAs |
Pinout & Package
MAX4753EUD+ is housed in a 14-pin TSSOP package (3.0mm × 4.4mm, 0.65mm pitch) with exposed pad not present - distinct from QFN variants. Pin 14 is V+, pins 7 and 13 are GND, and all IN_/COM_/NO_/NC_ terminals are assigned per functional diagram in datasheet Rev 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | CMOS-compatible logic signals enabling/disabling respective switches; no level-shifting required at +3V supply |
| COM1–COM4 | Common analog terminals | Bidirectional signal path nodes - may serve as input or output depending on system topology |
| NO1, NO3 | Normally open switch outputs | Connect to COMx only when corresponding INx = HIGH; default open state prevents leakage paths |
| NC2, NC4 | Normally closed switch outputs | Connect to COMx when corresponding INx = LOW; default closed state maintains continuity during standby |
| V+ | Positive supply | Single power rail for analog and digital sections; must be bypassed with 0.1µF capacitor to GND |
| GND (Pins 7, 13) | Analog/digital reference | Low-impedance return path shared by all channels; critical for minimizing RON variation and THD |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 2ns minimum dead time prevents simultaneous conduction in power routing or source selection |
| Rail-to-rail analog signal range | Supports full 0V to V+ swing - preserves dynamic range in unbuffered audio and sensor interfaces |
| Ultra-low leakage | ±5nA max off-leakage at TMAX - avoids DC error accumulation in high-impedance data-acquisition front-ends |
| High current capability | 100mA continuous per channel - sufficient for driving headphones, LEDs, or small solenoids directly |
| Low charge injection | 21pC typical - minimizes voltage glitch on sensitive nodes during switching, critical for precision ADC sample-hold |

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 |
|---|---|---|---|
| MAX4753EGE+T | 16-pin 3mm × 3mm QFN-EP package; identical electrical specs but different thermal performance (1349mW vs. 727mW dissipation) and layout footprint | Preferred for thermally constrained, high-density PCBs where exposed pad grounding improves thermal stability | Select MAX4753EGE+T when board area allows QFN and thermal management requires lower junction rise |
| TMUX1574PWR | TI part with 0.5Ω RON, no break-before-make, 1.08V–3.6V supply, and 1.2V logic compatibility - not functionally identical | Suitable for low-RON priority designs where break-before-make is unnecessary and logic voltage scaling is required | Choose TMUX1574PWR only if break-before-make is not needed and sub-1.8V logic interfacing is mandatory |
Compared with MAX4753EGE+T, MAX4753EUD+ offers proven TSSOP manufacturability and simpler thermal design; versus TMUX1574PWR, it delivers guaranteed break-before-make timing essential for power routing safety but requires 1.8V logic drive.

FAQ
What is the maximum continuous current rating per channel for MAX4753EUD+?
The MAX4753EUD+ supports 100mA continuous current per channel under specified thermal conditions. This rating applies to all COM_, NO_, and NC_ terminals and is validated across the full operating temperature range (–40°C to +85°C). Exceeding this current may increase RON drift or accelerate wear-out; peak pulsed current up to ±200mA is allowed at 10% duty cycle.
Does MAX4753EUD+ require external level-shifting when driven by a 1.8V microcontroller?
No, MAX4753EUD+ does not require external level-shifting when driven by a 1.8V microcontroller. Its digital inputs are 1.8V CMOS compatible at a +3V supply, with VIH_ = +1.4V min and VIL_ = +0.5V max. At lower supplies (e.g., +1.8V), VIH_ drops to +1.0V, still within standard 1.8V logic high margin. The MAX4753EUD+ accepts rail-to-rail input voltages up to +3.6V regardless of V+.
How is break-before-make timing verified for MAX4753EUD+?
Break-before-make timing for MAX4753EUD+ is guaranteed by design and characterized per Figure 1 in the datasheet, with tBBM = 2ns minimum at +3V, RL = 50Ω, CL = 35pF. It is not production-tested per unit but validated through process correlation and corner simulation across voltage/temperature extremes. The specification ensures no overlap between NO and NC conduction during IN_ transitions, critical for preventing supply shorts in power-routing applications.
Can MAX4753EUD+ switch signals beyond the V+ to GND range?
No, MAX4753EUD+ cannot reliably switch signals beyond the V+ to GND range. Its absolute maximum ratings limit COM_, NO_, and NC_ voltages to (V+ + 0.3V) and –0.3V, with internal clamping diodes conducting outside this window. Operation outside 0V to V+ increases leakage, degrades RON flatness, and risks permanent damage. For extended-range signals, external protection or alternative architectures (e.g., ±5V switches) are required.
What is the recommended power-supply bypassing for MAX4753EUD+?
A 0.1µF ceramic capacitor placed as close as possible between V+ (Pin 14) and GND (Pins 7 and 13) is the recommended bypass for MAX4753EUD+. This minimizes high-frequency supply noise coupling into analog paths and stabilizes switching transients. For systems with multiple MAX4753EUD+ devices or noisy environments, adding a 1µF bulk capacitor nearby further improves noise margin without affecting MAX4753EUD+ functionality.
