Product details
Overview
MAX4753EGE+T 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 supports rail-to-rail analog signals up to ±100mA continuous current - ideal for precision signal routing in battery-powered audio/video systems.
For engineers reviewing the MAX4753EGE+T datasheet, MAX4753EGE+T pinout, MAX4753EGE+T application, or MAX4753EGE+T equivalent, key selection criteria include verified break-before-make timing (2ns min), RON matching (0.12Ω max), low charge injection (21pC), 1.8V CMOS logic compatibility, and QFN-EP package thermal performance for high-density portable designs.
Technical Context
The MAX4753EGE+T implements CMOS-based quad SPST switching with independent NO/NC topology per channel pair, enabling simultaneous bidirectional signal routing and isolation. Its break-before-make architecture ensures no transient shorting between COM and NO/NC paths during state transitions, critical for power sequencing and analog multiplexing.
It operates across the full +1.6V to +3.6V supply range while maintaining guaranteed RON flatness (0.1Ω max) and matching (0.12Ω max) at +3V, with input logic thresholds (VIH = 1.4V, VIL = 0.5V) fully compatible with 1.8V CMOS drivers - eliminating level-shifting requirements in mixed-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 0.9Ω max at +3V supply - enables <10mV drop at 100mA, preserving signal integrity in low-voltage data acquisition. |
| Break-Before-Make Time (tBBM) | 2ns min - prevents momentary short-circuit during channel switching in power routing or sensor multiplexing. |
| Turn-On / Turn-Off Time | tON = 30ns, tOFF = 25ns - supports >10MHz digital control rates and fast analog signal switching. |
| RON Matching | 0.12Ω max between channels at +3V - ensures consistent gain/attenuation across multi-channel audio or sensor paths. |
| Charge Injection | 21pC max - minimizes voltage glitch on high-impedance nodes (e.g., ADC inputs or sample-hold circuits). |
| Supply Voltage Range | +1.6V to +3.6V - supports direct integration with Li-ion (3.0–3.6V) and coin-cell (1.8–2.2V) powered systems. |
| Logic Compatibility | 1.8V CMOS inputs at +3V supply - interfaces directly with modern low-voltage microcontrollers without translation. |
Pinout & Package
MAX4753EGE+T 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 1 is marked by a dot; EP must be soldered to a thermal pad on PCB for optimal power dissipation (1349mW max at TA = +70°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 11, 15 | NO1, NO3, COM1, COM3 | Pin 1 = NO1 (normally open), Pin 7 = COM1, Pin 11 = NO3, Pin 15 = COM3 - defines first NO/COM pair and third NO/COM pair. |
| 2, 8, 9, 16 | IN1, IN2, IN3, IN4 | Logic control inputs: HIGH enables NO path, LOW enables NC path per channel - direct 1.8V CMOS compatible. |
| 3, 10 | NC2, NC4 | Pin 3 = NC2, Pin 10 = NC4 - second and fourth normally closed terminals, active when corresponding INx = LOW. |
| 4, 5, 6, 12 | COM2, COM4, GND, V+ | Pin 4 = COM2, Pin 5 = COM4, Pin 6 = GND, Pin 12 = V+ - dual common paths, dedicated ground and supply pins for noise isolation. |
| 13, 14 | N.C., EP | Pin 13 = no connection; Pin 14 = exposed pad (EP) - must be connected to GND plane for thermal management and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 2ns minimum tBBM prevents cross-conduction during channel transition - essential for safe power domain isolation. |
| Rail-to-rail analog signal handling | Supports VCOM/VNO/VNC from GND to V+ - preserves full dynamic range of baseband audio and sensor outputs without clipping. |
| Ultra-low quiescent power | <1µW supply current - extends battery life in always-on monitoring systems and wearable devices. |
| Low off-capacitance | 31pF (NO/NC), 30pF (COM off) - minimizes crosstalk and bandwidth degradation in high-frequency video or RF sampling paths. |
| High off-isolation | -65dB at 1MHz - suppresses leakage between inactive channels in multi-source audio mixing or test equipment multiplexers. |
Applications

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+T | Same die, 14-pin TSSOP package - larger footprint, no exposed pad, lower thermal dissipation (727mW vs. 1349mW). | Suitable for prototyping or lower-power applications where PCB area and thermal budget allow TSSOP. | Select MAX4753EUD+T when board layout prioritizes hand-solderability or avoids QFN reflow complexity. |
| TMUX1574RSVR | TI part: 0.5Ω RON, but no break-before-make; 1.2V to 3.6V supply; 16-pin QFN same footprint. | Lacks guaranteed tBBM - unsuitable for power-path switching where short-through is unacceptable. | Choose TMUX1574RSVR only if lowest RON is primary requirement and break-before-make is not needed. |
Compared with MAX4753EGE+T, the MAX4753EUD+T offers identical electrical performance in a through-hole-friendly package but sacrifices thermal headroom, while the TMUX1574RSVR trades guaranteed break-before-make for lower on-resistance - making MAX4753EGE+T uniquely suited for safety-critical power and signal routing where transient isolation is mandatory.

FAQ
What is the maximum continuous current rating for MAX4753EGE+T?
The MAX4753EGE+T 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+T require external level shifters when driven by 1.8V logic?
No. The MAX4753EGE+T features 1.8V CMOS-compatible logic inputs when operated from a +3V supply - VIH is guaranteed ≥1.4V and VIL ≤0.5V, allowing direct connection to 1.8V microcontrollers or FPGAs without level-shifting circuitry. Input leakage remains below ±1µA across temperature.
How is break-before-make timing verified for MAX4753EGE+T?
Break-before-make timing (tBBM) for MAX4753EGE+T is guaranteed by design and characterized per Figure 1 in the datasheet, with a minimum value of 2ns at V+ = +3V, RL = 50Ω, CL = 35pF. It is not 100% production tested but validated through process correlation and simulation across voltage and temperature extremes.
Can MAX4753EGE+T handle analog signals beyond the supply rails?
No. The MAX4753EGE+T supports rail-to-rail analog signals only - VCOM, VNO, and VNC must remain within GND to V+. Signals exceeding V+ or GND are clamped by internal diodes; forward diode current must be limited to avoid damage. Absolute maximum ratings specify -0.3V to (V+ + 0.3V) for these pins.
What is the role of the exposed pad (EP) on the MAX4753EGE+T QFN package?
The exposed pad (EP) on the MAX4753EGE+T is electrically and thermally connected to GND. It must be soldered to a PCB ground plane to achieve specified thermal performance (1349mW max power dissipation at +70°C ambient) and reduce EMI. Leaving EP unconnected degrades both thermal resistance and high-frequency signal integrity.
