Product details
Overview
MAX4531EPP from Maxim Integrated is a dual 4-channel CMOS analog multiplexer configured for bidirectional rail-to-rail signal routing in industrial and test equipment. It operates from ±2V to ±6V dual supplies or +2V to +12V single supply, features 150Ω max on-resistance (±4.5V), 1nA max off-leakage at +25°C, and 150ns enable turn-on time - enabling precision low-power signal switching in battery-operated data acquisition systems.
For engineers reviewing the MAX4531EPP datasheet, MAX4531EPP pinout, MAX4531EPP application, or MAX4531EPP equivalent, key selection criteria include its -40°C to +85°C extended temperature rating, TTL/CMOS-compatible logic thresholds, break-before-make timing, address latching architecture, and compatibility with 74HC4352 pinout for drop-in replacement in legacy designs.
Technical Context
The MAX4531EPP integrates two independent 4-channel analog multiplexers (COMA/NO0A–NO3A and COMB/NO0B–NO3B) with shared digital control: dual enable inputs (EN1, EN2), three address bits (ADDA, ADDB, LE), and latch-enable functionality. Its CMOS switch core uses matched transistor pairs to ensure ≤8Ω on-resistance matching between channels.
It supports true rail-to-rail analog signal handling across its full supply range, with leakage currents specified down to 1nA at +25°C and 50nA at +85°C. The device employs internal level translators to drive analog switches from digital logic rails, isolating logic and analog supply domains while maintaining <1µW quiescent power consumption.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2V to ±6V dual or +2V to +12V single - enables operation in both bipolar sensor interfaces and low-voltage portable systems |
| On-Resistance (RON) | 150Ω max at +5V supply - ensures minimal signal attenuation and gain error in precision instrumentation paths |
| On-Resistance Matching | ≤8Ω max between channels - critical for multi-channel ratiometric measurements and channel-to-channel calibration |
| Off-Leakage Current | 1nA max at TA = +25°C - preserves high-impedance node integrity in sensitive front-end circuits |
| Enable Turn-On Time | 150ns at ±4.5V - supports fast multiplexing in real-time data acquisition up to ~3MHz channel rate |
| Rail-to-Rail Signal Handling | Full V− to V+ analog range - allows direct interfacing with op-amp outputs and ADC inputs without level-shifting |
| Logic Compatibility | 0.8V/2.4V thresholds - interoperates with both TTL and CMOS logic families using +5V or ±5V supplies |
Pinout & Package
MAX4531EPP is housed in a 20-pin plastic DIP package (0.300" wide) rated for -40°C to +85°C operation. Pin assignments are electrically identical to the MAX4531CPP/CWP series, with no internal connections at pins 3 and 14 (N.C.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive analog/digital supply | Drives internal CMOS switches and logic; sets upper analog signal limit |
| V− | Negative analog supply | Connect to GND for single-supply use; sets lower analog signal limit |
| GND | Digital ground reference | Reference for logic inputs and internal level translators only - not connected to analog path |
| COMA, COMB | Analog common terminals | Bidirectional signal hubs for respective 4-channel mux sections |
| NO0A–NO3A, NO0B–NO3B | Normally-open analog switch terminals | Interchangeable as inputs or outputs; support bidirectional signal flow |
| EN1, EN2 | Complementary enable logic inputs | Control activation of both mux sections independently or jointly |
| ADDA, ADDB | Address bit inputs | Select one of four channels per section (00–11 binary) |
| LE | Address latch enable | Freezes address state asynchronously - eliminates glitches during address transitions |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE WITH 74HC4352 | Direct mechanical and electrical replacement in existing PCB layouts designed for industry-standard dual 4:1 muxes |
| ADDRESS LATCHING (LE INPUT) | Eliminates need for synchronous clocking - enables stable channel selection even with noisy or slow-changing address lines |
| BREAK-BEFORE-MAKE SWITCHING | Guaranteed 4ns minimum interval prevents momentary shorting between channels during switching |
| RAIL-TO-RAIL® SIGNAL HANDLING | Supports full-scale analog signals from V− to V+ without clipping or distortion - essential for wide-dynamic-range systems |
| >2kV ESD PROTECTION (HBM) | Robust handling of electrostatic discharge during board assembly and field operation - reduces failure risk in unshielded environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4531CWP | Same electrical specs but 0°C to +70°C temperature range and 20-pin SO package | Suitable for commercial-grade, space-constrained PCBs where extended temp is not required | Select when operating environment stays within 0–70°C and SO-20 footprint is preferred over DIP |
| ADG408BRUZ | 8-channel single mux (not dual 4-channel); 100Ω RON typical; no address latching; different pinout | Requires PCB redesign; lacks LE input for asynchronous address hold | Choose only if single 8:1 topology fits system architecture and latch-free control is acceptable |

FAQ
What is the operating temperature range of the MAX4531EPP?
The MAX4531EPP is rated for operation from -40°C to +85°C, making it suitable for industrial and automotive environments where ambient temperatures exceed commercial-grade limits. This extended range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the official datasheet, and distinguishes it from the 'C' grade variants (0°C to +70°C). All electrical specifications in the datasheet are guaranteed across this full range.
Does the MAX4531EPP support single-supply operation?
Yes, the MAX4531EPP supports single-supply operation from +2V to +12V by connecting V− to GND. In this configuration, analog signals swing from 0V to V+, and logic thresholds remain TTL/CMOS-compatible. The datasheet specifies performance parameters including on-resistance (150Ω max at +5V), leakage (1nA at +25°C), and switching times under single-supply conditions - confirming full functionality without dual rails.
How does the address latch (LE) function in the MAX4531EPP?
The LE (Latch Enable) input in the MAX4531EPP captures and holds the current state of ADDA and ADDB address bits asynchronously - meaning it does not require synchronization with EN1/EN2. Once latched, channel selection remains stable regardless of subsequent address changes, preventing glitches during multiplexing. This feature is explicitly documented in the Truth Table and Applications Information sections of the datasheet.
Is the MAX4531EPP pin-compatible with the 74HC4352?
Yes, the MAX4531EPP is explicitly stated in the General Description to be pin compatible with the 74HC4352. Pin mapping matches exactly: COMA/COMB correspond to COM1/COM2, NO0A–NO3A and NO0B–NO3B align with Y0–Y3 of each section, and all control inputs (EN1, EN2, ADDA, ADDB, LE) occupy identical positions. This enables drop-in replacement without PCB modification.
What is the maximum allowable analog signal voltage range for the MAX4531EPP?
The MAX4531EPP supports rail-to-rail analog signals from V− to V+. With ±5V supplies, this means ±5V; with +5V/V− = GND, it means 0V to +5V. The Absolute Maximum Ratings specify that analog inputs must stay within -0.3V to (V+ + 0.3V), and the Electrical Characteristics confirm full-range operation - e.g., "Analog-Signal Range" is listed as V− to V+ across all supply configurations in the datasheet tables.
