Product details
Overview
MAX4530CWP from Maxim Integrated is an 8-channel CMOS analog multiplexer with dual enable inputs, address latching, and rail-to-rail signal handling. It operates from +2V to +12V single supply or ±2V to ±6V dual supplies, features 150Ω max on-resistance (±5V), 8Ω max channel matching, 1nA COM-off leakage at +25°C, and 150ns enable turn-on time - used in precision data acquisition and battery-powered test equipment.
For engineers reviewing the MAX4530CWP datasheet, MAX4530CWP pinout, MAX4530CWP application, or MAX4530CWP equivalent, key selection criteria include its 20-pin SO package, TTL/CMOS-compatible logic thresholds, break-before-make switching, ±5V supply performance, and compatibility with 74HC4351 pinout for drop-in replacement in legacy analog routing designs.
Technical Context
The MAX4530CWP implements a single 8:1 analog mux architecture with three address bits (ADDA, ADDB, ADDC), two independent enable inputs (EN1, EN2), and a latch-enable (LE) that freezes channel selection. Its CMOS transmission-gate design supports bidirectional rail-to-rail analog signals up to ±6V, with internal ESD protection (>2kV per Method 3015.7) and logic-level translators enabling operation across TTL- and CMOS-compatible voltage domains.
Switching behavior is governed by a break-before-make timing interval (4–10ns typ), minimizing transient shorts during channel transitions. Leakage currents are dominated by reverse-biased ESD diodes between NO/COM pins and V+/V−, resulting in temperature-dependent off-leakage (1nA @ +25°C, 50nA @ +85°C) and matched on-resistance flatness (13Ω typ over ±4.5V signal range).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 8-channel single-pole multiplexer (8:1) |
| Supply Range | +2V to +12V single supply or ±2V to ±6V dual supply - enables flexible power system integration |
| On-Resistance (RON) | 150Ω max at +5V supply - determines insertion loss and gain error in precision signal paths |
| On-Resistance Matching (∆RON) | 8Ω max between channels - critical for multi-channel instrumentation requiring consistent gain/attenuation |
| Off-Leakage Current | 1nA max at TA = +25°C - preserves accuracy in high-impedance sensor interfaces and sample-hold circuits |
| Enable Turn-On Time (tON) | 150ns max at ±4.5V - supports fast channel switching in automated test systems |
| Rail-to-Rail Signal Handling | Full analog swing from V− to V+ - allows direct interfacing with op-amps and ADCs without level-shifting |
Pinout & Package
MAX4530CWP is housed in a 20-pin SO (Small Outline) package, 7.5mm × 12.8mm body, 1.27mm pitch, with exposed pad not present. Pin functions are validated per Maxim's official pin description table and top-view schematic.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | Drives analog switches and internal logic; sets upper analog signal limit (V+) |
| V− | Negative supply input | Drives analog switches; sets lower analog signal limit (V−); connect to GND for single-supply use |
| GND | Digital ground reference | Reference for logic inputs and internal level translators; isolated from analog signal path |
| COM | Common analog terminal | Single bidirectional I/O node shared across all 8 channels; connects to selected NOx |
| NO0–NO7 | Normally open analog terminals | Eight independent bidirectional analog I/Os; only one connects to COM at a time under address control |
| EN1 / EN2 | Complementary enable inputs | Both must be asserted (EN1=low, EN2=high per truth table) to activate switching; provides redundancy and noise immunity |
| ADDA / ADDB / ADDC | 3-bit binary address inputs | Selects one of eight NOx channels (0–7); latched on rising edge of LE |
| LE | Latch-enable control | Freezes address bits at rising edge; decouples channel selection from address bus timing |
| N.C. | Not connected | Pins 3 and 14 - no internal connection; must remain unconnected on PCB |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE WITH 74HC4351 | Direct mechanical and functional replacement for industry-standard 8:1 mux - eliminates PCB redesign |
| Rail-to-Rail® Signal Handling | Supports analog signals spanning full V− to V+ range - enables seamless interface with ±5V op-amps and SAR ADCs |
| Break-Before-Make Switching | 4–10ns guaranteed interval prevents momentary shorting between channels - essential for fault-tolerant routing |
| TTL/CMOS-Compatible Logic Thresholds | 0.8V low / 2.4V high thresholds at +5V supply - ensures reliable digital control from microcontrollers and FPGAs |
| <1µW Quiescent Power | Sub-microwatt supply current at +25°C - extends battery life in portable DMMs and handheld analyzers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4530EWP | Same circuitry, -40°C to +85°C operating range vs. 0°C to +70°C for MAX4530CWP | Required for industrial or automotive environments with extended temperature exposure | Select MAX4530EWP when ambient operating temperature exceeds +70°C or falls below 0°C |
| ADG708BRUZ | 8:1 CMOS mux with 3.5Ω typical RON (vs. 150Ω), but only +1.8V to +5.5V supply range and no dual-enable architecture | Suitable for low-voltage, low-RON applications where ±5V operation and EN1/EN2 redundancy are unnecessary | Choose ADG708BRUZ for battery-powered IoT sensors needing ultra-low on-resistance, not legacy 74HC4351 pin compatibility |
Compared with MAX4530EWP, the MAX4530CWP offers identical functionality at lower cost for commercial-temperature applications; compared with ADG708BRUZ, it trades higher on-resistance for wider supply flexibility, robust dual-enable control, and direct 74HC4351 replacement capability.

FAQ
What is the maximum supply voltage rating for MAX4530CWP?
The MAX4530CWP has an absolute maximum rating of +13V on V+ relative to V−. It operates reliably across +2V to +12V single supply or ±2V to ±6V dual supplies. Exceeding ±6V on V− or applying more than +12V on V+ risks permanent damage due to internal ESD diode conduction and thermal overstress - always observe the Absolute Maximum Ratings table in the datasheet.
Does MAX4530CWP support true bidirectional analog signal flow?
Yes, the MAX4530CWP supports fully bidirectional analog signal routing. Its CMOS transmission-gate structure makes NOx and COM pins functionally identical and interchangeable - signals pass with equal integrity from NOx to COM or COM to NOx. This enables flexible use in both input multiplexing and output demultiplexing configurations without polarity constraints.
How does the latch-enable (LE) pin affect address timing in MAX4530CWP?
The LE pin captures and holds the ADDA/ADDB/ADDC address state on its rising edge, decoupling channel selection from address bus stability. Once latched, the selected channel remains active regardless of subsequent address changes - critical for noise-immune operation in electrically noisy environments like industrial PLCs or motor drives where address lines may glitch.
Can MAX4530CWP be used with a single +3.3V supply?
Yes, the MAX4530CWP operates down to +2V supply. At +3.3V, on-resistance increases to ~600Ω (typ), switching times lengthen (~350ns tTRANS), and logic thresholds shift slightly (VIL ≈ 0.8V, VIH ≈ 1.5V). It remains functional for low-speed, low-precision applications, but for optimal RON and speed, ±5V or +5V supply is recommended per the Electrical Characteristics tables.
What is the purpose of the dual enable inputs (EN1 and EN2) on MAX4530CWP?
EN1 and EN2 provide complementary enable control: the switch array activates only when EN1 is low and EN2 is high (per truth table). This dual-input scheme improves noise immunity, enables hardware interlock logic (e.g., safety-critical systems), and allows synchronous activation across multiple MAX4530CWP devices using a common clocked enable signal pair - reducing metastability risk versus single-enable architectures.
