Product details
Overview
MAX4782EUE+ from Maxim Integrated is a high-speed, low-voltage dual 4-channel CMOS analog multiplexer configured for bidirectional rail-to-rail signal routing. It operates from +1.6V to +3.6V, delivers 0.7Ω on-resistance at +3V, 11ns turn-on time, and supports ±150mA continuous channel current. It is used in battery-powered audio routing and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4782EUE+ datasheet, MAX4782EUE+ pinout, MAX4782EUE+ application, or MAX4782EUE+ equivalent, key selection criteria include on-resistance flatness (0.1Ω), break-before-make timing (18ns max), logic-level compatibility (+1.8V CMOS), and TSSOP-16 package compatibility with 74HC4052 and MAX4618.
Technical Context
The MAX4782EUE+ implements two independent 4:1 analog multiplexers sharing address inputs A and B, with separate X and Y output terminals. Each mux channel uses low-threshold CMOS transmission gates optimized for minimal RON variation across signal range (0–VCC) and temperature (−40°C to +85°C).
It features integrated digital enable control (active-high ENABLE pin), no internal pull-ups/pull-downs on address lines, and ESD-protected analog I/O capable of handling signals beyond supply rails via clamping diodes - enabling robust operation in mixed-signal systems with varying ground references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 0.7Ω at VCC = +3V - ensures <10mV drop at 14mA, critical for precision sensor multiplexing |
| On-Resistance Match | 0.3Ω max between channels - enables accurate ratiometric measurements across multiple sensor inputs |
| Turn-On Time (tON) | 11ns typical - supports >30MHz analog switching without signal distortion in high-speed DAQ |
| Analog Signal Range | Rail-to-rail (0V to VCC) - allows full utilization of ADC input range without level-shifting circuitry |
| Supply Voltage Range | +1.6V to +3.6V - compatible with Li-ion, coin-cell, and regulated 1.8V/3.3V system rails |
| Digital Input Threshold | VIL = 0.5V, VIH = 1.4V at +3V - ensures reliable interface with 1.8V CMOS microcontrollers |
| Off-Leakage Current | ±25nA max at +3.6V - preserves signal integrity in high-impedance sensor paths (e.g., thermocouples) |
Pinout & Package
MAX4782EUE+ is housed in a 16-pin TSSOP package (4.4mm × 5.0mm, 0.65mm pitch) with exposed pad not connected internally. Pin 1 is marked by a dot or notch; pin numbering follows JEDEC MS-013 standard, counterclockwise from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 2, 4 | Y0–Y3 | Analog inputs to second 4:1 mux - connect to four independent signal sources (e.g., sensors, DAC outputs) |
| 3 | Y | Common output for Y-mux - routed to ADC input, amplifier, or signal processor |
| 6 | ENABLE | Active-high global disable - pulls all switches open when high; tie to GND for always-enabled operation |
| 7 | N.C. | No internal connection - must be left floating or grounded; no routing required |
| 8 | GND | Analog/digital reference ground - requires low-impedance connection to system ground plane |
| 9, 10 | B, A | Binary address inputs (LSB first) - select Y0–Y3 and X0–X3 simultaneously; no internal termination |
| 12, 14, 15, 11 | X0–X3 | Analog inputs to first 4:1 mux - functionally identical to Y0–Y3 but electrically isolated |
| 13 | X | Common output for X-mux - provides second independent signal path, e.g., for differential pair or backup channel |
| 16 | VCC | Single positive supply - powers analog switches and digital logic; bypass with 100nF ceramic near pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports 0V to VCC signals without clipping - eliminates need for external biasing in single-supply systems |
| Low on-resistance flatness | 0.1Ω over full signal range - maintains gain accuracy in programmable-gain amplifier (PGA) front-ends |
| Break-before-make timing | 18ns maximum - prevents momentary shorting between channels during address transitions |
| Ultra-low quiescent power | 1µA ICC at VCC = 3.6V - extends battery life in portable medical and IoT edge devices |
| Pin-compatible replacement | Direct drop-in for 74HC4052 and MAX4618 - enables upgrade to lower RON and faster switching without PCB change |
Applications
| Audio Signal Routing | Low-Voltage Data-Acquisition Systems |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4618EUE+ | Higher RON (1.5Ω @ 3V), slower tON (25ns), same TSSOP-16 pinout | Lower bandwidth requirement (<10MHz), less sensitive to on-resistance mismatch | Select MAX4618EUE+ only if cost sensitivity outweighs performance needs; MAX4782EUE+ offers 53% lower RON and 56% faster switching. |
| 74HC4052D,653 | CMOS logic family; RON = 120Ω @ 4.5V, no guaranteed spec below 2V, no rail-to-rail support | Legacy industrial designs with 5V supplies and relaxed accuracy requirements | 74HC4052D,653 is viable only in 4.5–5.5V systems where 120Ω RON causes acceptable error; MAX4782EUE+ enables true 1.8V operation with 170× lower RON. |
Compared with MAX4618EUE+ and 74HC4052D,653, the MAX4782EUE+ uniquely combines sub-1Ω on-resistance, 11ns switching, and guaranteed 1.6V operation - making it the only option for precision, low-voltage, high-speed multiplexing in space-constrained portable electronics.

FAQ
What is the maximum analog signal voltage supported by MAX4782EUE+?
The MAX4782EUE+ supports rail-to-rail analog signals from 0V to VCC. When VCC = +3.6V, the absolute maximum analog input is +3.6V; signals exceeding VCC or going below GND are clamped by internal ESD diodes. Operation outside this range risks damage or increased leakage, so MAX4782EUE+ must be used within its specified supply and signal bounds.
Can MAX4782EUE+ operate from a 1.8V supply?
Yes, MAX4782EUE+ is fully specified down to +1.6V. At +1.8V supply, it delivers 1.6Ω typical on-resistance, 30ns turn-on time, and maintains +1.0V logic-high threshold - ensuring interoperability with 1.8V microcontrollers. All electrical characteristics in the datasheet include +1.8V test conditions, confirming robust functionality in ultra-low-power designs using MAX4782EUE+.
Is the ENABLE pin active-high or active-low for MAX4782EUE+?
The ENABLE pin of MAX4782EUE+ is active-high: driving it logic high disables both multiplexers (all channels open), while logic low enables normal address-controlled switching. The pin has no internal pull-up or pull-down, so external biasing is required if unused - typically tied to GND for default-enabled operation. This behavior is explicitly defined in the MAX4782EUE+ truth table and pin description.
Does MAX4782EUE+ support bidirectional signal flow?
Yes, MAX4782EUE+ supports fully bidirectional analog signal flow. Its CMOS transmission-gate architecture imposes no directionality - X0–X3 and Y0–Y3 can serve as inputs or outputs interchangeably, and X/Y terminals function identically as common ports. This is confirmed in the datasheet's "Pin Nomenclature" section, which states "Input and output pins are identical and interchangeable" for MAX4782EUE+.
What is the thermal performance of MAX4782EUE+ in TSSOP package?
The MAX4782EUE+ in TSSOP-16 has a thermal resistance θJA of 220°C/W and a maximum continuous power dissipation of 457mW at +70°C ambient. Derating is 5.7mW/°C above +70°C. With typical ICC < 1µA and RON < 1Ω, self-heating is negligible under normal operation - junction temperature rise remains <0.1°C at 100mA channel current, ensuring stable MAX4782EUE+ performance in sealed enclosures.
