Product details
Overview
The MAX4618CUE+ from Analog Devices is a high-speed, low-voltage CMOS dual 4-channel analog multiplexer configured for bidirectional signal routing in compact TSSOP-16 packaging. It operates from a single +2V to +5.5V supply, delivers 15ns turn-on time and 10ns turn-off time at +5V, maintains ≤10Ω on-resistance (max) and <0.017% THD at 600Ω - enabling precision audio and low-voltage data-acquisition applications.
For engineers reviewing the MAX4618CUE+ datasheet, MAX4618CUE+ pinout, MAX4618CUE+ application, or MAX4618CUE+ equivalent, this device serves as a pin-compatible upgrade to 74HC4052 and MAX4582 with verified rail-to-rail analog handling, guaranteed channel matching, and sub-1nA leakage at +25°C - critical for battery-powered instrumentation and signal-path switching where power efficiency and signal integrity are non-negotiable.
Technical Context
The MAX4618CUE+ integrates two independent 4-channel analog multiplexers sharing common digital control lines (A, B, ENABLE) and a single VCC/GND supply. Each 4:1 section routes one of four bidirectional analog inputs (X0–X3 or Y0–Y3) to its respective output (X or Y), with break-before-make switching and guaranteed 1Ω on-resistance match between channels at +5V.
Its BiCMOS process enables fast switching (tON/tOFF ≤15ns/10ns), low distortion (<0.017% THD), and high off-isolation (−93dB) and crosstalk rejection (−96dB) at 100kHz - all while supporting TTL/CMOS logic thresholds that scale with supply voltage (e.g., 2.4V high threshold at +5V, 2.0V at +3V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V single supply - supports direct integration into 3.3V and 5V systems without level-shifting. |
| On-Resistance (max) | 10Ω at +5V - ensures minimal signal attenuation and gain error in precision sensor or DAC/ADC interface paths. |
| On-Resistance Match | ≤1Ω between channels at +5V - preserves amplitude consistency across multiplexed channels in measurement systems. |
| Switching Speed | tON = 15ns, tOFF = 10ns (VCC = +5V) - enables reliable operation in high-sample-rate data acquisition and video routing. |
| Off-Leakage Current | 1nA at TA = +25°C - reduces DC offset drift in high-impedance sensor front-ends and battery-monitoring circuits. |
| Analog Signal Range | Rail-to-rail (0V to VCC) - allows full utilization of supply headroom for unipolar signal chains without clipping. |
| THD | <0.017% at 600Ω load - meets fidelity requirements for professional audio switching and low-distortion test equipment. |
Pinout & Package
MAX4618CUE+ uses a 16-pin TSSOP package (U16+2 outline, 90-0117 land pattern) with exposed pad not internally connected. Pin functions are defined per truth table and functional diagram in datasheet Rev 4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5 | X0–X3 analog inputs | Four bidirectional analog terminals for first 4:1 mux section; interchangeable as input or output. |
| 3 | X analog output | Common terminal for X-section; connects to selected X0–X3 channel when ENABLE = L and AB = valid code. |
| 10, 11, 13, 14 | Y0–Y3 analog inputs | Four bidirectional analog terminals for second 4:1 mux section; electrically isolated from X-section. |
| 15 | Y analog output | Common terminal for Y-section; independently controlled via same A/B/ENABLE logic. |
| 6 | ENABLE | Active-low global enable; drives all switches open (high-impedance) when logic high. |
| 7 | N.C. | No internal connection - must be left floating or tied to GND; no electrical function. |
| 8 | GND | Ground reference for analog and digital circuitry; return path for all leakage and switching currents. |
| 9, 12 | A, B address inputs | Binary select lines determining which of four inputs connects to X or Y output (C input absent on MAX4618). |
| 16 | VCC | Positive supply for CMOS switch core and logic; sets analog signal range limits and defines logic thresholds. |
Key Features
| Feature | Design Value |
|---|---|
| PIN-Compatible Upgrade Path | Direct drop-in replacement for 74HC4052 and MAX4582 - eliminates PCB redesign in legacy systems requiring improved speed or leakage. |
| Rail-to-Rail Analog Handling | Supports signals from 0V to VCC without distortion or clipping - essential for single-supply sensor interfaces and audio line-level routing. |
| Guaranteed Channel Matching | ≤1Ω on-resistance variation between channels at +5V - enables accurate ratiometric measurements and matched gain paths. |
| Low Distortion & High Isolation | <0.017% THD and −93dB off-isolation - preserves signal fidelity in professional audio, medical imaging, and test instrumentation. |
| Scalable Logic Thresholds | VIL = 0.8V / VIH = 2.4V at +5V; scales down to VIL = 0.5V / VIH = 2.0V at +3V - ensures robust digital control across mixed-voltage systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC4052D,653 | Slower switching (tON ≈ 75ns), higher RON (120Ω typ at +4.5V), no guaranteed RON match or THD spec. | Suitable for non-critical digital I/O or low-frequency analog routing; not recommended for audio or precision measurement. | Select MAX4618CUE+ when signal integrity, speed, or channel matching is required; choose 74HC4052 only for cost-sensitive, low-performance use cases. |
| MAX4582ESE+ | Same pinout and function but rated for −40°C to +85°C industrial temp range; otherwise identical electrical specs. | Preferred for extended-temperature deployments (e.g., automotive body control, outdoor telecom); MAX4618CUE+ limited to 0°C to +70°C. | Choose MAX4618CUE+ for commercial-grade applications with tight cost targets; select MAX4582ESE+ when extended temperature operation is mandatory. |
Compared with 74HC4052D and MAX4582ESE+, the MAX4618CUE+ delivers superior speed, lower on-resistance, guaranteed matching, and verified THD - making it optimal for high-fidelity, high-throughput analog routing where performance outweighs marginal cost differences.

FAQ
What is the operating temperature range for the MAX4618CUE+?
The MAX4618CUE+ is specified for commercial temperature operation from 0°C to +70°C. This range is confirmed in the Ordering Information table (Rev 4, page 14) and applies to all electrical characteristics unless otherwise noted. It is not rated for extended industrial temperatures (−40°C to +85°C); for that range, consider the MAX4618EUE+ variant. The MAX4618CUE+ uses a lead(Pb)-free TSSOP-16 package compliant with RoHS directives.
Does the MAX4618CUE+ support rail-to-rail analog signal switching?
Yes, the MAX4618CUE+ supports rail-to-rail analog signal switching - meaning it can pass signals from 0V up to VCC without clipping or distortion. This capability is explicitly stated in the General Description and Electrical Characteristics sections (page 2, "Analog-Signal Range" parameter). It enables full utilization of supply headroom in single-supply systems such as portable sensors and audio line drivers, and is intrinsic to its CMOS switch architecture.
Is the MAX4618CUE+ pin-compatible with standard logic multiplexers?
Yes, the MAX4618CUE+ is pin-compatible with the industry-standard 74HC4052 and the earlier MAX4582. This compatibility is confirmed in the Features section (page 1) and Applications Information (page 9), which state explicit pin-for-pin equivalence in TSSOP-16 packaging. Functionally, it replicates the dual 4:1 configuration with shared A/B/ENABLE controls, allowing direct substitution without layout changes - provided temperature and performance requirements align.
What is the maximum on-resistance of the MAX4618CUE+ and under what conditions is it specified?
The maximum on-resistance of the MAX4618CUE+ is 10Ω, specified at VCC = +4.5V to +5.5V, with IX/IY = 10mA and VX/VY = 3V, at TA = +25°C (Electrical Characteristics table, page 2). At +3V supply, RON increases to 20Ω max. This parameter is production-tested and guaranteed - critical for minimizing gain error in precision amplifier or ADC front-end designs where channel resistance directly impacts accuracy.
Can the MAX4618CUE+ be used with a 2.5V supply?
Yes, the MAX4618CUE+ can operate with a +2.5V supply, though performance degrades: on-resistance rises to 30–60Ω (typ/max), switching times increase to ~12ns, and logic thresholds scale downward (VIH ≈ 1.7V). While functional per Absolute Maximum Ratings and Typical Operating Characteristics (pages 5–6), Analog Devices does not guarantee full specification compliance below +2.7V. For robust 2.5V operation, verify timing and RON in-system; the +2V minimum is an absolute limit, not a recommended operating point.
