Product details
Overview
MAX4530EWP 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 ±6V dual supplies or +2V to +12V single supply, features 150Ω max on-resistance (±5V), 8Ω max channel matching, and 1nA COM-off leakage at +25°C. It is used in battery-powered data acquisition systems requiring low-power, high-precision analog switching.
For engineers reviewing the MAX4530EWP datasheet, MAX4530EWP pinout, MAX4530EWP application, or MAX4530EWP equivalent, key selection criteria include its -40°C to +85°C extended temperature rating, 20-pin SO package, break-before-make timing (10ns typ), <1µW quiescent power, and compatibility with TTL/CMOS logic levels across supply ranges.
Technical Context
The MAX4530EWP implements a single 8:1 analog multiplexer architecture with three address bits (ADDA, ADDB, ADDC), two independent enable inputs (EN1, EN2), and a latch-enable (LE) for synchronous channel selection. Its CMOS switch core uses matched P/N transistor pairs to achieve low RON flatness (10Ω typ) and minimal charge injection (1.5pC).
All digital inputs feature fixed 0.8V/2.4V thresholds-ensuring reliable operation with both TTL and CMOS logic across ±5V and +5V supplies. The device includes internal ESD protection (>2kV per Method 3015.7) and supports bidirectional signal flow on all NO/COM pins without ground reference dependency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2V to ±6V dual or +2V to +12V single-supports wide-range battery and industrial rails without level-shifting. |
| On-Resistance (RON) | 150Ω max at +5V supply-enables ≤0.1% gain error in 10kΩ sensor interfaces. |
| RON Matching | 8Ω max between channels-critical for precision ratiometric measurements across multiple sensors. |
| Off-Leakage Current | 1nA at TA = +25°C, 50nA at +85°C-preserves accuracy in high-impedance pH or thermocouple front-ends. |
| Switching Speed | tON = 150ns, tOFF = 120ns at ±4.5V-supports >1MHz multiplexed sampling in portable test equipment. |
| Logic Compatibility | 0.8V/2.4V thresholds-interoperates directly with 3.3V/5V microcontrollers and FPGAs without glue logic. |
| ESD Protection | >2kV per Method 3015.7-meets IEC 61000-4-2 Level 2 for handheld instrumentation robustness. |
Pinout & Package
MAX4530EWP is housed in a 20-pin SO (Small Outline) package, 7.5mm × 12.8mm body, 1.27mm pitch, RoHS-compliant, with exposed pad not connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive analog/digital supply | Drives internal switch gates and logic; sets upper analog signal limit (up to V+). |
| V- | Negative analog supply | Drives switch gates; sets lower analog signal limit (down to V-); connect to GND for single-supply use. |
| GND | Digital ground reference | Reference for logic inputs only; isolated from analog signal path and supplies. |
| COM | Common analog terminal | Bidirectional node shared by all 8 switched paths; accepts rail-to-rail signals from V- to V+. |
| NO0–NO7 | Normally open analog inputs/outputs | Eight independent analog terminals; each connects to COM when selected; fully interchangeable as input or output. |
| ADDA, ADDB, ADDC | Binary address inputs | 3-bit code selects one of eight NOx channels; latched on LE rising edge. |
| EN1, EN2 | Complementary enable controls | Both must be asserted (EN1=LOW, EN2=HIGH) to activate switching; enables power-gating per section. |
| LE | Latch-enable input | Edge-triggered control that freezes address bits; decouples channel selection from address bus timing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog operation | Signals swing from V- to V+ without clipping-enables full dynamic range utilization in ±5V sensor interfaces. |
| Break-before-make switching | 10ns typical interval prevents momentary shorting between channels-essential for avoiding signal crosstalk in multi-sensor systems. |
| Low charge injection (1.5pC) | Minimizes voltage glitch on high-impedance nodes (e.g., sample-hold capacitors), preserving ADC accuracy. |
| Pin compatibility with 74HC4351 | Direct drop-in replacement for legacy TTL-compatible muxes-reduces redesign effort in avionics and ATE upgrades. |
| Ultra-low power (<1µW) | Enables always-on monitoring in battery-critical applications like portable gas analyzers or wearable biosensors. |

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 functionality but rated for 0°C to +70°C commercial temperature range; identical pinout and electrical specs. | Suitable for non-extended-temperature industrial or consumer applications where ambient stays within 0–70°C. | Select MAX4530CWP for cost-sensitive designs without extended temperature requirements. |
| ADG708BRUZ | 8-channel CMOS mux with 3.5Ω typical RON (at +5V), but no address latching or dual enable; operates only on +1.8V to +5.5V single supply. | Used in low-voltage portable electronics where latch-free asynchronous control suffices and tighter RON is prioritized. | Choose ADG708BRUZ when ultra-low on-resistance is critical and system-level latching is handled externally. |
Compared with MAX4530CWP, the MAX4530EWP adds guaranteed operation down to -40°C-making it suitable for outdoor or automotive-adjacent deployments. Against ADG708BRUZ, MAX4530EWP trades lower RON for integrated latching, dual enable, and wider supply flexibility-reducing external logic count in embedded control systems.

FAQ
What is the operating temperature range of the MAX4530EWP?
The MAX4530EWP is specified for continuous operation from -40°C to +85°C. This extended industrial temperature range is validated per Maxim's production testing and ensures reliable performance in automotive under-hood modules, outdoor instrumentation, and avionics subsystems where ambient extremes occur. The MAX4530EWP maintains all key parameters-including RON, leakage, and switching speed-within datasheet limits across this full range.
Does the MAX4530EWP support single-supply operation?
Yes, the MAX4530EWP supports single-supply operation from +2V to +12V. To configure for single supply, connect V- to GND. All analog signals remain rail-to-rail (0V to V+), and logic inputs retain TTL/CMOS compatibility. At +5V supply, RON is 150Ω max; at +12V, it drops to ~75Ω. The device draws <1µW quiescent power in this mode, making it ideal for battery-backed systems.
How does the address latching function work on the MAX4530EWP?
The MAX4530EWP uses a positive-edge-triggered latch-enable (LE) input to capture and hold the state of ADDA, ADDB, and ADDC address lines. When LE transitions from LOW to HIGH, the current 3-bit address is stored internally, allowing the selected channel (NO0–NO7) to remain active even if address lines change afterward. This eliminates bus contention and simplifies timing in microcontroller-driven systems where address and data share a common bus.
Can the MAX4530EWP handle bipolar analog signals?
Yes-the MAX4530EWP fully supports bipolar analog signals when operated from dual supplies (e.g., ±5V). With V+ = +5V and V- = -5V, analog signals can swing from -5V to +5V on all NO/COM pins. The device's CMOS switch architecture and symmetric threshold design ensure distortion-free passage of AC-coupled or DC-biased signals, including audio, sensor outputs, and control voltages in industrial PLC I/O modules.
Is the MAX4530EWP pin-compatible with the 74HC4351?
Yes, the MAX4530EWP is explicitly designed as a pin-compatible, functionally enhanced replacement for the 74HC4351. It shares identical 20-pin SO footprint, pin assignments (including V+, GND, COM, NO0–NO7, ADDA–ADDC, EN1/EN2, LE), and truth table behavior. Unlike the 74HC4351, the MAX4530EWP adds rail-to-rail operation, lower leakage, higher ESD tolerance, and extended temperature support-enabling direct upgrade without PCB modification.
