Product details
Overview
MAX4531EWP+T from Maxim Integrated is a dual 4-channel CMOS analog multiplexer with address latching and dual enable inputs, configured as two independent 4:1 muxes (COMA/NO0A–NO3A and COMB/NO0B–NO3B). It operates from ±2V to ±6V dual supplies or +2V to +12V single supply, delivers 150Ω max on-resistance at +5V, matches channels within 8Ω, and supports rail-to-rail analog signals up to ±4.5V. It is used in precision data acquisition systems requiring low leakage and fast switching.
For engineers reviewing the MAX4531EWP+T datasheet, MAX4531EWP+T pinout, MAX4531EWP+T application, or MAX4531EWP+T equivalent, this page provides verified specifications, package mapping, functional alternatives, and design-critical timing and leakage data - all confirmed for the -40°C to +85°C industrial-grade SO-20 variant.
Technical Context
The MAX4531EWP+T implements two independent 4:1 analog multiplexers with shared address lines (ADDA, ADDB), separate enable inputs (EN1, EN2), and a latch-enable (LE) that freezes channel selection. Each mux features complementary switch-enable logic and TTL/CMOS-compatible digital inputs with 0.8V/2.4V thresholds.
Its internal architecture uses matched CMOS transmission gates driven by level-translated logic, enabling rail-to-rail signal handling across V+ to V−. On-resistance flatness is ≤100Ω over the full analog range, and break-before-make timing ensures no signal shorting during channel transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2V to ±6V dual or +2V to +12V single - supports battery-powered and industrial rails without level shifters |
| On-Resistance (RON) | 150Ω max at +5V supply - ensures minimal signal attenuation in sensor and audio paths |
| RON Matching | 8Ω max between channels - critical for gain-matched multi-channel instrumentation |
| Off-Leakage Current | 50nA max at +85°C - preserves accuracy in high-impedance measurement front-ends |
| Switching Speed | tON = 150ns, tOFF = 120ns at ±4.5V - enables sub-microsecond channel switching in ATE |
| Rail-to-Rail Support | VCOM/VNO = V− to V+ - allows full-swing AC/DC signals without clipping or biasing |
| ESD Protection | >2kV per Method 3015.7 - enhances robustness in handling-sensitive test and avionics environments |
Pinout & Package
MAX4531EWP+T is housed in a 20-pin wide SOIC (SO-20) package, 7.5mm body width, 1.27mm pitch, RoHS-compliant, with exposed pad not present.
| 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 | Drives analog switches; connect to GND for single-supply operation |
| GND | Digital ground reference | Reference for logic inputs only; isolated from analog signal path |
| LE | Latch-enable input | Freezes ADDA/ADDB state to select channel; independent of EN1/EN2 |
| EN1, EN2 | Enable inputs for MUX A and MUX B | Active-high control: both must be high to enable respective 4:1 path |
| ADDA, ADDB | Binary address inputs | Selects one of four NOx inputs per mux (00→NO0, 11→NO3) |
| COMA, COMB | Common outputs for MUX A and MUX B | Output node shared across four analog inputs; bidirectional signal path |
| NO0A–NO3A, NO0B–NO3B | Analog inputs for MUX A and MUX B | Eight total switch terminals; each pair shares common COM and enable |
| N.C. | Not connected | Pins 3 and 14 are unconnected - no internal bond wire or circuitry |
Key Features
| Feature | Design Value |
|---|---|
| PIN-Compatible with 74HC4352 | Direct drop-in replacement for legacy logic-controlled analog muxes without PCB redesign |
| Rail-to-Rail® Signal Handling | Supports analog signals from V− to V+ - eliminates need for external biasing in ±5V or +5V systems |
| Address Latching (LE) | Decouples channel selection from address bus timing - simplifies microcontroller interface and reduces noise coupling |
| Break-Before-Make Switching | 4ns min tBBM interval prevents momentary shorting between channels - essential for fault-tolerant routing |
| TTL/CMOS-Compatible Inputs | 0.8V/2.4V thresholds work with +5V microcontrollers and FPGAs without level-shifting circuitry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-channel analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRUZ | Single 8:1 mux (not dual 4:1); 70Ω RON at +5V; no address latch; SPI-compatible control | Requires external decoding logic for dual-path operation; better for space-constrained single-path designs | Select when needing lower on-resistance and serial control, but accept added logic overhead and loss of independent enable per mux |
| TS3A4751PWR | Single-supply only (+1.65V to +3.6V); 0.9Ω RON at +3.3V; no dual enable; no latch; 1.5pC charge injection | Optimized for portable audio and USB-C analog switches; incompatible with ±5V or industrial rails | Select for ultra-low-voltage battery-powered audio routing, but not for dual-supply or industrial temperature operation |
Compared with ADG408BRUZ and TS3A4751PWR, the MAX4531EWP+T uniquely provides dual independent 4:1 muxes with latched addressing, ±6V capability, and industrial temperature range - making it irreplaceable in ATE and avionics where channel isolation, supply flexibility, and timing determinism are mandatory.

FAQ
What is the operating temperature range for MAX4531EWP+T?
The MAX4531EWP+T is rated for -40°C to +85°C, qualifying it for industrial and avionics environments. This extended range is confirmed in the Ordering Information table and validated across all electrical parameters including leakage current, on-resistance, and switching speed - unlike the commercial-grade C-suffix variants limited to 0°C to +70°C.
Does MAX4531EWP+T support single-supply operation?
Yes, MAX4531EWP+T operates from a single +2V to +12V supply when V− is tied to GND. Electrical characteristics including 150Ω max on-resistance and 50nA max off-leakage at +85°C are fully specified under +5V single-supply conditions, and rail-to-rail signal handling remains intact from 0V to V+.
How does the latch-enable (LE) pin function in MAX4531EWP+T?
The LE pin latches the state of ADDA and ADDB inputs to freeze channel selection independently of EN1/EN2. When LE is high, address changes immediately affect routing; when LE is low, the last valid address is held. This decouples timing-critical address updates from enable control - a key feature for deterministic switching in microcontroller-based systems using MAX4531EWP+T.
Is MAX4531EWP+T pin-compatible with 74HC4352?
Yes, MAX4531EWP+T is explicitly designed as a pin-compatible upgrade to the 74HC4352 dual 4:1 analog multiplexer. Pin functions, numbering, and SO-20 footprint match exactly - enabling direct replacement without layout changes while adding rail-to-rail operation, lower leakage, and latch-enable functionality not present in the HC device.
What is the maximum allowable supply voltage for MAX4531EWP+T?
The absolute maximum rating for V+ is +13V referenced to V−, and for any analog terminal it is (V+ + 0.3V) or −0.3V - whichever occurs first. Operation beyond ±6V dual or +12V single supply risks permanent damage. These limits are defined in the Absolute Maximum Ratings table and apply regardless of temperature or duration.
