Product details
Overview
MAX4530EAP 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 single +2V to +12V or dual ±2V to ±6V supplies, delivers ≤150Ω on-resistance (max), ≤8Ω channel matching, and 1nA off-leakage at +25°C - enabling precision signal routing in battery-powered data acquisition systems.
For engineers reviewing the MAX4530EAP datasheet, MAX4530EAP pinout, MAX4530EAP application, or MAX4530EAP equivalent, key selection criteria include its -40°C to +85°C industrial temperature range, 20-pin SSOP package, TTL/CMOS-compatible logic thresholds, break-before-make switching, and compatibility with 74HC4351 pinout for drop-in replacement in legacy analog routing designs.
Technical Context
The MAX4530EAP 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 asynchronously. Its CMOS switch core uses matched P/N transistor pairs to achieve low on-resistance flatness (≤13Ω) and rail-to-rail analog conduction across the full supply range.
Switching performance is defined by 120ns tOFF and 150ns tON at ±4.5V, 1.5pC charge injection, and <2000V HBM ESD protection. Digital inputs meet both TTL and CMOS thresholds (0.8V/2.4V) across supply voltages, ensuring interoperability with mixed-logic systems without level translation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 8-channel single-pole multiplexer (8:1) |
| Supply Range | +2V to +12V (single) or ±2V to ±6V (dual) - supports portable and bipolar-signal systems |
| On-Resistance (RON) | 150Ω max at +5V supply - ensures minimal signal attenuation in sensor and audio paths |
| On-Resistance Matching | 8Ω max between channels - critical for gain-matched multi-channel instrumentation |
| Off-Leakage Current | 1nA at +25°C, 50nA at +85°C - preserves accuracy in high-impedance measurement front-ends |
| Switching Speed | tON = 150ns, tOFF = 120ns at ±4.5V - enables sub-microsecond channel settling in ATE |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V) - eliminates external level shifters in +5V microcontroller interfaces |
Pinout & Package
MAX4530EAP is housed in a 20-pin SSOP (Shrink Small Outline Package) with 0.65mm pitch, footprint-compatible with industry-standard 20-pin SO and DIP variants. The package supports reflow soldering and offers improved thermal resistance over DIP for high-density PCB layouts.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6, 16, 17, 18, 19 | NO0–NO7 | Normally open analog switch terminals - bidirectional, interchangeable with COM |
| 4 | COM | Common analog terminal - connects to selected NOx channel when enabled |
| 7, 8 | EN1, EN2 | Complementary enable inputs - both must be asserted for channel activation (active-high logic) |
| 10 | GND | Digital ground reference - isolated from analog V− but tied internally to substrate |
| 11 | LE | Latch-enable input - captures ADDA/ADDB/ADDC state asynchronously to freeze channel selection |
| 12, 13, 15 | ADDA, ADDB, ADDC | 3-bit binary address inputs - select one of eight NOx channels (0–7) |
| 9 | V− | Negative analog supply - connect to GND for single-supply operation |
| 20 | V+ | Positive analog/digital supply - powers both switch core and logic circuitry |
| 3, 14 | N.C. | No internal connection - must remain unconnected per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4351 | Direct mechanical and functional replacement for legacy HC-series muxes without PCB redesign |
| Rail-to-rail signal handling | Analog signals swing from V− to V+ - supports full-scale sensor outputs and audio waveforms |
| Break-before-make switching | Guaranteed 4ns minimum interval prevents momentary shorting during channel transitions |
| Low power consumption | <1µW quiescent power - extends battery life in portable medical and test equipment |
| High ESD robustness | >2kV HBM per Method 3015.7 - reduces field failure risk in handling and assembly |
| Temperature-rated operation | -40°C to +85°C range - qualified for industrial control and avionics environments |

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 electrical specs, 20-pin SO package (1.27mm pitch) - larger footprint, higher thermal resistance | Suitable for through-hole prototyping or legacy SO-based designs where SSOP reflow is unavailable | Select when board assembly process lacks SSOP capability or requires manual soldering access |
| ADG708BRUZ | 8:1 mux with 3.5Ω typical RON, +1.8V to +5.5V supply only, no dual-enable or latch-enable inputs | Optimized for low-voltage portable systems; lacks address latching and complementary enable logic | Choose for ultra-low RON in 3.3V-only systems where static channel selection suffices |
Compared with MAX4530EWP, the MAX4530EAP offers superior board density and thermal performance in SSOP; versus ADG708BRUZ, it provides industrial temperature support, latch functionality, and wider supply flexibility at the cost of higher RON.

FAQ
What is the operating temperature range of the MAX4530EAP?
The MAX4530EAP is rated for operation from -40°C to +85°C, making it suitable for industrial and automotive-adjacent applications where ambient conditions exceed commercial-grade limits. This extended range is confirmed in the Ordering Information table and validated across all electrical parameters in the datasheet's "E" grade specifications.
Does the MAX4530EAP support single-supply operation?
Yes, the MAX4530EAP supports single-supply operation from +2V to +12V with V− connected to GND. At +5V, it achieves 150Ω max on-resistance and maintains TTL/CMOS logic compatibility - enabling direct interface with microcontrollers and ADCs without dual-rail supplies.
Is the MAX4530EAP pin-compatible with the 74HC4351?
Yes, the MAX4530EAP is explicitly designed as a pin-compatible upgrade to the 74HC4351. Pin functions, layout, and signal routing match identically - allowing drop-in replacement in existing designs while adding rail-to-rail operation, lower leakage, and extended temperature support.
What is the purpose of the LE (Latch Enable) pin on the MAX4530EAP?
The LE pin on the MAX4530EAP asynchronously latches the ADDA/ADDB/ADDC address inputs, freezing the selected channel independently of EN1/EN2 state. This allows stable channel selection even when address lines are shared or toggling - essential for glitch-free operation in noisy digital environments.
How does the MAX4530EAP handle analog signal directionality?
The MAX4530EAP supports bidirectional analog signal flow: NOx and COM pins are functionally identical and interchangeable. Signals pass equally well from NOx to COM or COM to NOx, enabling flexible use as either a multiplexer or demultiplexer without redesigning the analog path.
