Product details
Overview
MAX4530EWP+T 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 (±4.5V), <1nA COM-off leakage at +25°C, and 150ns enable turn-on time - enabling precise signal routing in battery-powered test equipment and avionics data acquisition systems.
For engineers reviewing the MAX4530EWP+T datasheet, MAX4530EWP+T pinout, MAX4530EWP+T application, or MAX4530EWP+T equivalent, key selection criteria include its -40°C to +85°C extended temperature rating, 20-pin wide SO package, TTL/CMOS-compatible logic thresholds, break-before-make switching, and verified pin compatibility with 74HC4351.
Technical Context
The MAX4530EWP+T 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) for asynchronous channel selection. Its internal CMOS switch array uses matched transistor pairs to achieve ≤8Ω on-resistance matching and ≤150Ω max RON across the full analog signal range (rail-to-rail).
Switch control logic supports both latched and transparent modes: when LE is high, address inputs directly select channels; when LE is low, the last valid address is held. Dual-supply operation enables true bipolar signal switching (±6V), while ESD protection (>2kV per Method 3015.7) and <1µW quiescent power support rugged, low-power embedded designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2V to ±6V dual or +2V to +12V single - supports rail-to-rail analog signals without level-shifting circuitry |
| On-Resistance (RON) | 150Ω max at +5V supply - ensures minimal signal attenuation and gain error in precision measurement paths |
| On-Resistance Matching | 8Ω max between channels - critical for multi-channel instrumentation requiring consistent channel-to-channel gain |
| COM-Off Leakage | 1nA max at +25°C - preserves signal integrity in high-impedance sensor interfaces and sample-hold circuits |
| Enable Turn-On Time | 150ns at ±4.5V - enables fast channel switching in real-time data acquisition and ATE applications |
| Logic Thresholds | 0.8V low / 2.4V high - guarantees interoperability with both TTL and CMOS logic families across supply voltages |
| ESD Protection | >2kV per Method 3015.7 - provides robust handling during board assembly and field deployment |
Pinout & Package
MAX4530EWP+T is housed in a 20-pin wide SO (Small Outline) package, 7.5mm body width, 1.27mm pitch, RoHS-compliant, with exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive analog/digital supply | Drives internal CMOS switches and logic; sets upper analog signal limit (+12V max) |
| V- | Negative analog supply | Drives analog switches; connects to GND for single-supply operation (±2V to ±6V range) |
| GND | Digital ground reference | Reference for logic inputs and internal level translators; isolated from analog signal paths |
| COM | Common analog terminal | Shared connection point for all 8 switched channels; bidirectional, rail-to-rail capable |
| NO0–NO7 | Normally-open analog terminals | Eight independent analog inputs/outputs; interchangeable with COM; no polarity constraints |
| EN1 / EN2 | Complementary enable inputs | Both must be asserted for channel conduction; enables independent section control or global disable |
| ADDA / ADDB / ADDC | 3-bit binary address inputs | Select one of eight NOx channels to connect to COM; latched via LE signal |
| LE | Latch-enable control | When high: addresses update in real time; when low: holds last selected channel address |
| N.C. | No-connect pins | Pins 3 and 14 are unconnected internally - must remain floating or grounded per layout best practices |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail® Signal Handling | Analog signals swing from V− to V+ without clipping - eliminates need for external biasing in ±5V or +5V systems |
| Break-Before-Make Switching | 4ns min break interval prevents momentary shorting during channel transitions - essential for fault-tolerant routing |
| Address Latching | LE input freezes channel selection independently of address changes - enables glitch-free reconfiguration under noise |
| Pin Compatibility | Direct replacement for 74HC4351 - allows drop-in upgrade of legacy TTL-based mux designs with improved analog performance |
| Low Charge Injection | 1.5pC typical - minimizes voltage disturbance in sample-and-hold and switched-capacitor circuits |
| Wide Temperature Range | -40°C to +85°C operation - qualified for industrial and avionics environments without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4530CWP+ | 0°C to +70°C temperature range; otherwise identical electrical specs and pinout | Not suitable for extended-temperature industrial or avionics use | Select MAX4530CWP+ only for commercial-grade applications where ambient temperature stays within 0–70°C |
| ADG708BRUZ | 8-channel CMOS mux, but 3.3V/5V single-supply only; no dual-supply capability; 4Ω RON matching | Lacks ±6V bipolar signal support and extended temperature grade | Choose ADG708BRUZ for cost-sensitive, single-supply 3.3V/5V systems where bipolar operation is unnecessary |
Compared with MAX4530CWP+, the MAX4530EWP+T adds guaranteed -40°C to +85°C operation and enhanced reliability screening; versus ADG708BRUZ, it delivers dual-supply flexibility and higher voltage tolerance at the expense of slightly higher on-resistance - making it the preferred choice for ruggedized, wide-swing analog routing.

FAQ
What is the operating temperature range of the MAX4530EWP+T?
The MAX4530EWP+T is rated for operation from -40°C to +85°C. This extended temperature range is validated per Maxim's E-grade qualification standard and makes the device suitable for industrial control, avionics, and outdoor instrumentation applications where ambient conditions exceed commercial-grade limits. The MAX4530EWP+T maintains specified on-resistance, leakage, and switching timing across this full range.
Is the MAX4530EWP+T pin-compatible with the 74HC4351?
Yes, the MAX4530EWP+T is explicitly designed as a pin-compatible upgrade to the industry-standard 74HC4351. Pin assignments for V+, V-, GND, COM, NO0–NO7, EN1, EN2, ADDA, ADDB, ADDC, LE, and N.C. match identically. This allows direct PCB replacement without layout modification, delivering superior analog performance - including rail-to-rail operation, lower leakage, and enhanced ESD protection - over the legacy TTL device.
Can the MAX4530EWP+T operate from a single +3.3V supply?
Yes, the MAX4530EWP+T supports single-supply operation down to +2V, including +3.3V. At +3.3V, on-resistance increases to approximately 600Ω (typical), and switching times lengthen - but all logic thresholds remain compatible with standard 3.3V CMOS levels. For optimal analog performance, use ±3V or +5V supplies; +3.3V is viable for low-speed, low-precision routing where RON variation is acceptable.
What does "Rail-to-Rail®" mean for the MAX4530EWP+T?
"Rail-to-Rail®" means the MAX4530EWP+T can pass analog signals from the negative supply rail (V−) to the positive supply rail (V+) without clipping or distortion. When operated on ±5V supplies, it handles ±5V input signals fully; on +5V/0V supplies, it passes 0V to +5V signals. This eliminates external biasing networks and simplifies interface design with op-amps, ADCs, and sensors that output full-supply-range signals.
How is channel selection latched in the MAX4530EWP+T?
Channel selection in the MAX4530EWP+T is controlled by the LE (Latch Enable) pin. When LE is high, the ADDA/ADDB/ADDC inputs directly determine the active channel in real time. When LE is pulled low, the internal address register holds the last valid combination, maintaining the selected channel regardless of subsequent address changes - preventing glitches during dynamic reconfiguration. This latching behavior is independent of EN1/EN2 states.
