Product details
Overview
MAX4530CPP 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 (8Ω matching), 1nA off-leakage at +25°C, and 150ns turn-on time - enabling precise signal routing in battery-powered data acquisition systems.
For engineers reviewing the MAX4530CPP datasheet, MAX4530CPP pinout, MAX4530CPP application, or MAX4530CPP equivalent, key selection criteria include its 20-pin DIP package, TTL/CMOS-compatible logic thresholds, break-before-make switching, ±5V supply performance (75Ω RON), and ESD robustness (>2kV per Method 3015.7).
Technical Context
The MAX4530CPP implements a single 8:1 analog multiplexer with three address bits (ADDA, ADDB, ADDC), two independent enable inputs (EN1, EN2), and a latch-enable (LE) for asynchronous channel selection. Its CMOS switch architecture uses complementary transistor pairs driven by level-translated logic to support rail-to-rail analog signals across the full supply range.
Switching behavior is governed by a break-before-make timing interval (4–10ns typ), minimizing transient shorts during channel transitions. Internal ESD protection diodes connect each NO/COM pin to V+ and V−, defining absolute maximum analog voltage limits and contributing to leakage current that varies with signal voltage and temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply or ±2V to ±6V dual supply - supports portable and industrial rails without level shifters |
| On-Resistance (RON) | 75Ω typ at ±5V, 150Ω max at +5V - ensures minimal signal attenuation and gain error in precision measurement paths |
| RON Matching | 8Ω max between channels - critical for matched gain/attenuation in multi-channel instrumentation |
| Off-Leakage Current | 1nA at +25°C, 50nA at +85°C - preserves accuracy in high-impedance sensor interfaces and sample-hold circuits |
| Switching Speed | tON = 150ns, tOFF = 120ns at ±4.5V - enables sub-microsecond channel scanning in automated test equipment |
| Logic Compatibility | 0.8V/2.4V thresholds - interoperates directly with TTL and CMOS logic at +5V or ±5V supplies |
| ESD Protection | >2kV per Method 3015.7 - withstands handling and board-level transients without external protection |
Pinout & Package
MAX4530CPP is housed in a 20-pin plastic DIP package (0.300" wide), compatible with through-hole prototyping and legacy industrial PCBs. Pin assignments follow standard analog mux layout with dedicated COM, NO0–NO7, address, enable, and supply terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive analog/digital supply | Drives internal switch gates and logic; sets upper analog signal limit (V+) |
| V− | Negative analog supply | Drives switch gates; sets lower analog signal limit (V−); tie to GND for single-supply operation |
| GND | Digital ground reference | Reference for logic inputs and internal level translators; isolated from analog signal path |
| COM | Common analog terminal | Single-pole connection point shared across all 8 channels; bidirectional signal path |
| NO0–NO7 | Normally open analog inputs | Eight independent analog inputs; only one connects to COM at a time per address decode |
| ADDA, ADDB, ADDC | Address select inputs | 3-bit binary code selects active channel (0–7); latched on LE rising edge |
| EN1, EN2 | Complementary enable inputs | Both must be asserted (EN1=low, EN2=high) to activate switching; enables power-gating |
| LE | Latch-enable control | Edge-triggered input captures address bits; decouples channel selection from address bus timing |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE WITH 74HC4351 | Direct drop-in replacement for industry-standard 8:1 mux, enabling legacy design upgrades without PCB change |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4530CWP | Same die, 20-pin SO package - 7.5mm × 12.8mm footprint vs. DIP's 6.35mm pitch | Preferred for space-constrained PCBs; requires reflow soldering instead of through-hole assembly | Select when board density or automated assembly outweighs prototyping convenience of DIP. |
| ADG708BRUZ | 8:1 CMOS mux with 3.5Ω RON, 1.8–5.5V supply, no dual enable or latch - SPI interface instead of parallel address | Suited for low-voltage, low-RON apps but lacks LE/EN2 for synchronous control in legacy MCU designs | Choose for ultra-low on-resistance or digital-control systems; not pin-compatible with MAX4530CPP. |
Compared with MAX4530CWP, the MAX4530CPP offers identical electrical performance in a through-hole package ideal for lab validation and low-volume production; versus ADG708BRUZ, it provides parallel-address latching and dual enable for deterministic timing in real-time embedded systems, albeit with higher RON.

FAQ
What supply voltages does the MAX4530CPP support?
The MAX4530CPP operates from a single +2V to +12V supply (with V− tied to GND) or dual ±2V to ±6V supplies. At ±5V, it achieves 75Ω typical on-resistance and full rail-to-rail analog signal handling. The device tolerates absolute maximum ratings up to +13V on V+ and −0.3V on any terminal relative to V−, making it suitable for both portable and industrial power domains. MAX4530CPP maintains specified performance across its entire operating temperature range of 0°C to +70°C.
How does the latch-enable (LE) function work on the MAX4530CPP?
The LE input on the MAX4530CPP is an edge-triggered control that captures the state of ADDA, ADDB, and ADDC address lines on its rising edge. Once latched, the selected channel remains active regardless of subsequent address changes - decoupling channel selection timing from address bus stability. This allows microcontrollers to update address lines asynchronously and assert LE only when valid data is present, simplifying timing-critical interfaces. MAX4530CPP retains the latched state until LE is pulsed again or power is cycled.
Is the MAX4530CPP pin-compatible with the 74HC4351?
Yes, the MAX4530CPP is explicitly designed as a pin-compatible and functionally equivalent replacement for the 74HC4351 8:1 analog multiplexer. Both share identical 20-pin DIP pinouts, address decoding (ADDA/ADDB/ADDC), enable logic (EN1/EN2), and COM/NO0–NO7 terminal assignments. MAX4530CPP improves upon the 74HC4351 with lower on-resistance (75Ω vs. ~100Ω), rail-to-rail signal capability, and integrated ESD protection - enabling direct substitution in existing designs without layout modification.
What is the maximum analog signal range supported by the MAX4530CPP?
The MAX4530CPP supports true rail-to-rail analog signals from V− to V+, meaning its input/output voltage range spans the full supply differential. With ±5V supplies, this delivers a ±5V (10Vpp) analog range; with +5V/V−=GND, it supports 0V to +5V signals. Internal ESD diodes clamp signals exceeding V+ or falling below V−, so the absolute analog range is bounded by the supply rails. MAX4530CPP maintains specified leakage and on-resistance across this full range, ensuring consistent performance in sensor front-ends and DAC output stages.
Does the MAX4530CPP require external components for basic operation?
No, the MAX4530CPP requires no external passive components for fundamental operation. Its internal level translators, latch circuitry, and ESD protection eliminate the need for pull-up resistors, series termination, or external clamps in most applications. Only bypass capacitors (e.g., 0.1µF ceramic near V+/V− pins) are recommended for noise suppression. MAX4530CPP's TTL/CMOS-compatible logic thresholds (0.8V/2.4V) allow direct interfacing with microcontrollers and FPGAs without level-shifting circuitry - simplifying system integration and reducing bill-of-materials count.
