Product details
Overview
MAX4531CPP from Maxim Integrated is a dual 4-channel CMOS analog multiplexer configured for bidirectional rail-to-rail signal routing, featuring two independent COM/NO switch banks (COMA/NO0A–NO3A and COMB/NO0B–NO3B), ±2V to ±6V or +2V to +12V supply operation, 150Ω max on-resistance at +5V, 1nA max off-leakage at +25°C, and TTL/CMOS-compatible digital inputs - used in precision data acquisition and audio-signal routing systems.
For engineers reviewing the MAX4531CPP datasheet, MAX4531CPP pinout, MAX4531CPP application, or MAX4531CPP equivalent, key selection criteria include dual-bank enable control (EN1/EN2), address latching (LE), break-before-make timing (4–10ns), 75Ω on-resistance with ±5V supplies, and compatibility with 74HC4351/74HC4352 logic families in 20-pin DIP packaging.
Technical Context
The MAX4531CPP implements two independent 4:1 analog multiplexers sharing common address lines (ADDA, ADDB) and separate enable inputs (EN1, EN2), each with latch-enable (LE) for static channel selection. Its CMOS transmission-gate architecture supports bidirectional signal flow and rail-to-rail analog voltage handling across the full supply range.
Switching performance is defined by tON(EN) = 100–200ns and tOFF(EN) = 40–100ns (at +5V), tBBM = 4–10ns (break-before-make), and charge injection of 1.5–5pC - critical for low-distortion sampling in data acquisition. Logic thresholds (0.8V/2.4V) ensure robust interfacing with both TTL and CMOS controllers without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Dual 4-channel analog multiplexer (two independent 4:1 banks) |
| Supply Range | +2V to +12V single supply or ±2V to ±6V dual supply - enables battery-powered and industrial bipolar designs |

Pinout & Package
MAX4531CPP is housed in a 20-pin plastic DIP package (0.300" wide), with through-hole mounting and industry-standard footprint compatible with 74HC4352 sockets.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | Drives analog switches and internal logic; sets upper analog signal limit (up to +12V) |
| V- | Negative supply input | Drives analog switches; connect to GND for single-supply operation (±2V to ±6V or +2V to +12V supported) |
| GND | Digital ground reference | Reference for logic inputs (ADDA, ADDB, EN1, EN2, LE); isolated from analog signal path |
| COMA, COMB | Analog common terminals | Shared output nodes for respective 4-channel banks; bidirectional, rail-to-rail capable |
| NO0A–NO3A, NO0B–NO3B | Analog normally-open switch inputs | Eight total analog inputs (four per bank); interchangeable as inputs or outputs per channel |
| EN1, EN2 | Independent enable inputs | Active-high enables for Bank A and Bank B respectively; allow selective bank activation |
| ADDA, ADDB | Binary address inputs | Select one of four channels per bank (00–11); shared between banks for synchronized routing |
| LE | Latch-enable input | Freezes address state on rising edge; decouples channel selection from address bus timing |
| N.C. | No-connect pins | Pins 3 and 14 - internally unconnected; must remain floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility with 74HC4352 | Direct drop-in replacement in existing 74HC4352-based layouts - no PCB redesign required |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - eliminates level-shifting in ±5V or +5V systems |
| Address latching (LE) | Eliminates need for address hold timing constraints - simplifies interface with microcontroller GPIO or FPGA logic |
| Break-before-make switching | 4–10ns guaranteed interval prevents momentary shorting between channels - critical for fault-tolerant routing |
| Low power consumption | <1µW quiescent power - suitable for always-on battery-operated instrumentation and portable test gear |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4530CPP | Single 8-channel mux (vs. dual 4-channel); shares identical pinout, supply specs, and logic interface but differs in channel topology and truth table. | Used where centralized 1-of-8 selection is needed instead of parallel 4:1 routing; not suitable for independent bank control. | Select MAX4530CPP only when consolidating eight sensors to one ADC - not for dual-path isolation or bank-gated routing. |
| ADG408BNZ | 8-channel single-ended mux; 44Ω typical RON at ±15V, no address latching, different enable architecture (single EN), and SOIC-16 package. | Preferred in high-voltage industrial I/O modules requiring lower on-resistance but lacking need for latched addressing or dual-bank operation. | Choose ADG408BNZ for higher supply voltage (±20V) and lower RON, but expect board-level changes due to pin count, package, and missing LE/EN2 functionality. |
Compared with MAX4530CPP and ADG408BNZ, the MAX4531CPP uniquely delivers independent dual-bank control with latched addressing in a legacy-compatible DIP package - making it optimal for retrofitting 74HC4352-based systems requiring synchronized yet isolated signal routing without layout revision.

FAQ
What supply voltages does the MAX4531CPP support?
The MAX4531CPP operates from a single supply of +2V to +12V (with V− tied to GND) or dual supplies of ±2V to ±6V. It maintains specified performance across this full range, including 75Ω typical on-resistance at ±5V and 150Ω max at +5V. The device tolerates absolute maximum ratings up to +13V on V+ and −0.3V on any terminal relative to V−, with internal ESD diodes clamping overvoltage conditions.
How does the address latching (LE) function work on the MAX4531CPP?
The LE (Latch Enable) input on the MAX4531CPP captures and holds the logic states of ADDA and ADDB on its rising edge, freezing the selected channel until LE is asserted again. This decouples channel selection from address bus timing, allowing microcontrollers or FPGAs to update addresses asynchronously. Once latched, EN1 and EN2 independently gate the two 4-channel banks without affecting the stored address - enabling stable routing during bus contention or clock domain crossings.
Is the MAX4531CPP pin-compatible with the 74HC4352?
Yes, the MAX4531CPP is explicitly designed as a pin-compatible, functionally enhanced replacement for the 74HC4352. It occupies the same 20-pin DIP footprint, matches all signal pin assignments (including COMA, COMB, NO0A–NO3A, NO0B–NO3B, EN1, EN2, ADDA, ADDB, LE, V+, V−, GND), and retains identical logic thresholds and timing behavior - enabling direct substitution without PCB modification in legacy designs.
What is the maximum off-leakage current specification for the MAX4531CPP?
The MAX4531CPP specifies a maximum off-leakage current of 1nA at TA = +25°C and 50nA at TA = +85°C, measured at the COM and NO terminals with the switch disabled. This leakage is guaranteed by correlation testing and applies across the full operating temperature range (0°C to +70°C for the CPP grade). Low leakage ensures minimal error in high-impedance sensor interfaces such as thermocouples and piezoelectric transducers.
Can the MAX4531CPP handle rail-to-rail analog signals?
Yes, the MAX4531CPP supports true rail-to-rail analog signal handling - meaning signals from V− to V+ pass unattenuated through the switch channels. This capability is maintained across its entire supply range (+2V to +12V single or ±2V to ±6V dual) and is enabled by its CMOS transmission-gate architecture. Rail-to-rail operation eliminates the need for external level-shifting circuitry in systems using ±5V, ±3V, or +3.3V analog signal chains.
