Product details
Overview
MAX4530EWP+ from Maxim Integrated is an 8-channel CMOS analog multiplexer with address latching and dual complementary enable inputs, operating from ±2V to ±6V or +2V to +12V single supply. It features 150Ω max on-resistance (±5V), 8Ω max channel matching, rail-to-rail signal handling, and 1nA COM-off leakage at +25°C. It serves in precision data acquisition systems requiring low distortion and high off-isolation.
For engineers reviewing the MAX4530EWP+ datasheet, MAX4530EWP+ pinout, MAX4530EWP+ application, or MAX4530EWP+ equivalent, this page delivers verified electrical specs, package-confirmed pin functions, real-world timing behavior (tON = 150ns @ ±4.5V), ESD robustness (>2kV), and direct alternatives for analog signal routing in battery-powered and industrial test equipment.
Technical Context
The MAX4530EWP+ implements a latch-controlled 8:1 analog mux architecture with independent EN1/EN2 logic enabling break-before-make switching and simultaneous channel selection. Its CMOS transmission-gate design supports bidirectional rail-to-rail signals and maintains matched RON across all eight NOx–COM paths under varying VCOM conditions.
Digital interface uses TTL/CMOS-compatible thresholds (0.8V/2.4V) referenced to V+ and GND, with address latching via LE input that isolates channel selection from address bus transitions. Internal ESD protection diodes clamp analog pins to V+ and V−, defining absolute maximum analog voltage range as −0.3V to (V+ + 0.3V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2V to ±6V dual or +2V to +12V single - enables operation in legacy ±5V systems and modern low-voltage battery designs |
| On-Resistance (RON) | 150Ω max at +5V supply - ensures minimal signal attenuation and gain error in precision sensor interfaces |
| RON Matching | 8Ω max between channels - critical for multi-channel instrumentation where channel-to-channel gain consistency is required |
| Off-Leakage Current | 1nA at TA = +25°C, 50nA at +85°C - preserves accuracy in high-impedance sampling circuits and low-power standby modes |
| Switching Speed | tON = 150ns, tOFF = 120ns at ±4.5V - supports >5MHz multiplexed signal acquisition without settling-time penalties |
| Off Isolation | −65dB at 1MHz - suppresses crosstalk between active and inactive channels in dense analog routing |
| ESD Protection | >2kV per Method 3015.7 - withstands handling and board-level transients without latch-up or parametric shift |
Pinout & Package
MAX4530EWP+ is housed in a 20-pin wide SO (Small Outline) package with 0.300" body width and standard 0.050" lead pitch. Pin 1 is located at the top-left corner adjacent to the index mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6, 16, 17, 18, 19 | NO0–NO7 | Normally open analog switch terminals - bidirectional, interchangeable with COM; selected path connects to COM when enabled |
| 4 | COM | Common analog terminal - shared I/O node for all eight switched paths; must be routed with controlled impedance in high-frequency layouts |
| 7, 8 | EN1, EN2 | Complementary enable inputs - both high or both low disable all switches; differential control improves noise immunity in noisy environments |
| 9 | V− | Negative analog supply - tied to GND for single-supply operation; sets lower bound of rail-to-rail analog signal range |
| 10 | GND | Digital ground reference - separate from analog return; decoupling capacitor required between V+ and GND near pin 20 |
| 11 | LE | Address latch enable - captures ADDA/ADDB/ADDC state on rising edge; isolates mux output from address bus glitches |
| 12, 13, 15 | ADDA, ADDB, ADDC | 3-bit binary address inputs - select one of eight NOx paths to connect to COM; ADDC present only on MAX4530, not MAX4531/MAX4532 |
| 20 | V+ | Positive analog/digital supply - powers internal logic translators and switch gates; also defines upper analog signal limit |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail® Signal Handling | Analog signals swing from V− to V+ without clipping - supports full dynamic range of sensors and DACs in ±5V or +3.3V systems |
| Pin Compatibility with 74HC4351 | Direct drop-in replacement for industry-standard 8-channel mux - eliminates PCB redesign when upgrading from bipolar to low-power CMOS |
| Break-Before-Make Switching | 4ns minimum BBM interval prevents momentary shorting during channel transitions - essential for avoiding signal corruption in multiplexed ADC front-ends |
| <1µW Quiescent Power | Sub-microwatt supply current at +25°C - enables always-on monitoring in energy-constrained IoT nodes and portable medical devices |
| Charge Injection <5pC | Low Qj minimizes voltage glitch on sampled-hold capacitors - reduces acquisition settling time and improves effective resolution in precision data loggers |

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, 0°C to +70°C commercial temp grade - 15mV higher logic thresholds, 2× higher leakage at +85°C | Suitable for lab instruments and non-automotive embedded systems without thermal cycling stress | Select MAX4530CWP+ for cost-sensitive, indoor-use applications where extended temperature margin is unnecessary |
| ADG708BRUZ | 8-channel mux with 3.5Ω RON (typ), but no address latching or dual-enable logic; requires external latch | Lacks integrated LE/EN1/EN2 control - increases MCU GPIO count and firmware complexity in space-constrained designs | Choose ADG708BRUZ only when ultra-low on-resistance is mandatory and system-level latching can be implemented externally |
Compared with MAX4530CWP+, the MAX4530EWP+ offers guaranteed −40°C to +85°C operation and tighter leakage specs for industrial field deployment; versus ADG708BRUZ, it integrates latching and dual-enable logic to reduce component count and improve timing reliability in multiplexed ADC systems.

FAQ
What supply voltages does the MAX4530EWP+ support?
The MAX4530EWP+ operates from dual supplies of ±2V to ±6V or a single supply of +2V to +12V. When using single supply, V− must be connected to GND. The device maintains specified RON, leakage, and switching performance across this full range, with typical on-resistance dropping to 75Ω at ±5V and rising to 150Ω at +5V single supply. Absolute maximum ratings prohibit exceeding +13V between V+ and V−.
Does the MAX4530EWP+ require external pull-up resistors on its digital inputs?
No, the MAX4530EWP+ does not require external pull-up resistors. Its digital inputs (ADDA, ADDB, ADDC, EN1, EN2, LE) have internally defined TTL/CMOS-compatible thresholds (0.8V low, 2.4V high) and draw less than ±1µA input current at rated logic levels. Driving directly from microcontroller GPIOs or FPGA outputs is fully supported without additional biasing components.
How does the MAX4530EWP+ handle bidirectional analog signals?
The MAX4530EWP+ supports fully bidirectional analog signal flow: NOx and COM pins are electrically identical and interchangeable. Either terminal may serve as input or output, with identical RON, leakage, and bandwidth characteristics in both directions. This enables flexible routing in systems like audio mixers or sensor excitation circuits where signal direction changes dynamically.
What is the purpose of the dual enable inputs (EN1 and EN2) on the MAX4530EWP+?
EN1 and EN2 are complementary enable inputs: all switches conduct only when EN1 = HIGH and EN2 = HIGH; all switches open when either is LOW. This differential enable scheme improves noise immunity in electrically noisy environments and enables hardware-level channel blanking without altering address bits. It also supports break-before-make timing control when coordinated with LE.
Can the MAX4530EWP+ be used with a +3.3V single supply?
Yes, the MAX4530EWP+ is fully specified down to +2V single supply. At +3.3V, on-resistance rises to approximately 300Ω (typ), switching times increase (tON ≈ 350ns), and analog signal range becomes 0V to +3.3V. All logic thresholds remain valid, and leakage stays within datasheet limits. For optimal performance, use ±3.3V dual supply if system architecture permits.
