Product details
Overview
MAX4611EPD from Maxim Integrated is a quad, low-voltage, single-pole/single-throw (SPST) CMOS analog switch with normally closed (NC) configuration, 100Ω max on-resistance at +5V supply, 4Ω max channel-to-channel on-resistance match, and rail-to-rail analog signal handling from V+ to GND. It operates from a single +2V to +12V supply and targets precision signal routing in battery-powered instrumentation.
For engineers reviewing the MAX4611EPD datasheet, MAX4611EPD pinout, MAX4611EPD application, or MAX4611EPD equivalent, key selection criteria include guaranteed on-resistance flatness (18Ω max), sub-2nA off-leakage at +85°C, TTL/CMOS logic compatibility at +5V, and 14-pin plastic DIP packaging for through-hole prototyping and industrial control interfaces.
Technical Context
The MAX4611EPD implements four independent NC switches using matched CMOS transmission-gate architecture, with all digital inputs referenced to a single V+ supply and grounded substrate. Its on-resistance remains flat across the full analog signal range (0V to V+), enabling low-distortion signal switching without level-shifting.
Each switch supports bidirectional analog signals up to ±0.3V beyond rails via internal clamping diodes, while leakage currents are specified and tested over temperature (–40°C to +85°C). Logic thresholds (VIN_H = 2.4V, VIN_L = 0.8V at +5V supply) ensure robust interfacing with standard microcontroller GPIOs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V single supply - enables direct integration into 3.3V, 5V, and 9V systems without level shifters |
| On-Resistance (max) | 100Ω at +5V - ensures minimal voltage drop and signal attenuation in low-current analog paths |
| On-Resistance Match | 4Ω max between channels - critical for matched gain/attenuation in multi-channel instrumentation front-ends |
| Off-Leakage Current | 2nA at +85°C - preserves accuracy in high-impedance sample-and-hold and sensor multiplexing |
| Analog Signal Range | V+ to GND - supports rail-to-rail input/output without external biasing in unipolar systems |
| Logic Compatibility | TTL/CMOS at +5V (VIN_H = 2.4V, VIN_L = 0.8V) - interoperable with legacy and modern digital controllers |
| Turn-On/Off Time | 65ns / 28ns typical - suitable for multiplexed data acquisition up to ~10MHz sampling rates |
Pinout & Package
MAX4611EPD is housed in a 14-pin plastic DIP (dual in-line package) with 0.3-inch body width and through-hole mounting. Pin 7 is GND; pins 1, 3, 8, and 11 are NC terminals; pins 2, 4, 9, and 10 are COM terminals; pins 13, 5, 6, and 12 are IN control inputs; pin 14 is V+; no exposed pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NC1–NC4 | Normally closed analog output terminals - conduct to COM when IN = LOW; open when IN = HIGH |
| 2, 4, 9, 10 | COM1–COM4 | Common analog node per switch - bidirectional path between NC and signal source/load |
| 13, 5, 6, 12 | IN1–IN4 | Digital control inputs - TTL/CMOS-compatible; active-low logic controls NC closure |
| 7 | GND | Digital and substrate ground reference - must be connected to system ground plane |
| 14 | V+ | Positive supply for analog and digital circuitry - bypass with 0.1µF ceramic capacitor near pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog voltages from GND to V+ without clipping or distortion in unipolar systems |
| Guaranteed on-resistance flatness | 18Ω max variation across full signal range - maintains consistent gain/attenuation in audio and sensor paths |
| Matched channel on-resistance | 4Ω max difference between any two switches - enables precise ratio-metric measurements in multi-channel muxes |
| Low off-leakage current | <2nA at +85°C - prevents charge injection errors in high-Z sample-and-hold and capacitive sensing circuits |
| ESD protection | >2kV per Method 3015.7 - improves robustness during board assembly and field operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4611EUD+ | Same electrical specs, 14-pin TSSOP package - 5mm × 4.4mm surface-mount footprint | Preferred for space-constrained PCBs; requires reflow assembly instead of through-hole | Select for automated SMT production; MAX4611EPD remains optimal for hand-soldered prototypes and legacy DIP layouts |
| ADG1411BRZ | Quad SPST NC switch with 1.8Ω on-resistance match but higher 1.5nA leakage at +85°C; requires dual ±15V or single +36V supply | Targeted at high-precision test equipment, not low-voltage battery systems | Choose only if ultra-low RON mismatch is critical and supply exceeds +12V; incompatible with 3.3V/5V-only designs |
Compared with MAX4611EUD+, MAX4611EPD offers identical analog performance in a serviceable through-hole package, while ADG1411BRZ trades lower on-resistance matching for higher supply voltage and leakage - making MAX4611EPD the optimal choice for cost-sensitive, low-voltage, manually assembled industrial and medical applications.

FAQ
What is the maximum supply voltage rating for MAX4611EPD?
The absolute maximum V+ rating for MAX4611EPD is +13V referenced to GND. Operation above +12V is not recommended due to increased on-resistance variation and potential reliability risk. The device is characterized and guaranteed from +2V to +12V, with on-resistance dropping to 45Ω typical at +12V. Always use a 0.1µF ceramic bypass capacitor close to the V+ pin when operating near the upper limit.
Does MAX4611EPD support bidirectional analog signal flow?
Yes, MAX4611EPD supports fully bidirectional analog signal flow between COM and NC terminals. Its CMOS transmission-gate structure has no inherent directionality, and the datasheet specifies symmetric analog signal range (0V to V+) and matched on-resistance in both directions. This enables use in AC-coupled audio paths and sensor excitation-return configurations without polarity constraints.
Can MAX4611EPD be used with a 3.3V logic supply?
Yes, MAX4611EPD accepts 3.3V logic inputs when operated from a +5V or higher V+ supply. Its input thresholds are fixed (VIN_H = 2.4V min, VIN_L = 0.8V max at +5V), so a 3.3V GPIO driving INx will reliably register as HIGH. However, do not power V+ from 3.3V if using 3.3V logic - on-resistance rises to 360Ω typical, degrading signal fidelity. Use V+ ≥ 4.5V for best performance.
What is the thermal resistance (θJA) of the MAX4611EPD package?
The MAX4611EPD in its 14-pin plastic DIP package has a junction-to-ambient thermal resistance (θJA) of 100°C/W, based on the datasheet's derating specification: 800mW continuous power dissipation at +70°C ambient, derating 10.00mW/°C above that. This value assumes standard JEDEC 2-layer board conditions and confirms suitability for non-forced-air industrial environments up to +85°C ambient.
Is MAX4611EPD RoHS-compliant and lead-free?
Yes, MAX4611EPD carries the "+" suffix per Maxim's ordering nomenclature, indicating it is lead(Pb)-free and RoHS-compliant. The plastic DIP package uses matte tin lead finish and complies with EU Directive 2011/65/EU. No exemptions apply, and the device meets JEDEC J-STD-609 Category 1 marking requirements for lead-free identification.
