Product details
Overview
MAX4530CWP+ from Maxim Integrated is an 8-channel CMOS analog multiplexer with address latching and dual enable inputs, configured for rail-to-rail signal routing in ±2V to ±6V or +2V to +12V supplies. It delivers 150Ω max on-resistance, 8Ω max channel matching, 1nA COM-off leakage at +25°C, and 150ns enable turn-on time - enabling precise signal selection in battery-powered data acquisition and test equipment.
For engineers reviewing the MAX4530CWP+ datasheet, MAX4530CWP+ pinout, MAX4530CWP+ application, or MAX4530CWP+ equivalent, key selection criteria include its 20-pin SO package, TTL/CMOS-compatible logic thresholds (0.8V/2.4V), break-before-make switching, charge injection of 1.5pC, and guaranteed operation across 0°C to +70°C.
Technical Context
The MAX4530CWP+ implements a single 8:1 analog mux architecture with three address bits (ADDA, ADDB, ADDC), latch-enable (LE), and two independent enable inputs (EN1, EN2) that support hierarchical channel control. Its CMOS switch array uses matched transistor pairs to achieve ≤8Ω on-resistance matching and <1µW quiescent power consumption.
Internal ESD protection (>2kV per Method 3015.7) and rail-to-rail analog signal handling (VCOM/VNO = V− to V+) are maintained across dual-supply (±2V to ±6V) and single-supply (+2V to +12V) configurations. Logic inputs tolerate TTL- and CMOS-level signals without level-shifting when operated at ±5V or +5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single or ±2V to ±6V dual - supports wide input voltage flexibility without external regulators |
| On-Resistance (RON) | 150Ω max at +5V supply - ensures minimal signal attenuation in precision analog paths |
| RON Matching | 8Ω max between channels - critical for gain-matched multi-channel instrumentation |
| Off-Leakage Current | 1nA at TA = +25°C - preserves signal integrity in high-impedance sensor interfaces |
| Enable Turn-On Time | 150ns at ±4.5V - enables fast channel switching in automated test systems |
| Charge Injection | 1.5pC - limits voltage glitch on sampled-hold nodes in data acquisition front-ends |
| Logic Thresholds | 0.8V low / 2.4V high - ensures reliable interface with both TTL and CMOS controllers |
Pinout & Package
MAX4530CWP+ is housed in a 20-pin SO (Small Outline) package with 0.300" body width and standard JEDEC MS-013AC footprint. Pin 1 is located at the top-left corner adjacent to the index mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive analog/digital supply | Drives internal switch gates and logic; sets upper analog signal limit (V+) |
| NO0–NO7 | Analog switch outputs/inputs | Eight bidirectional, interchangeable normally-open terminals; routed to COM when selected |
| COM | Common analog terminal | Bidirectional common node; connects to one NOx channel per address state |
| N.C. | Not connected | Pins 3 and 14 are unconnected - no internal bond wire or circuit connection |
| ADDA, ADDB, ADDC | Address inputs | 3-bit binary select lines determining which NOx connects to COM (000–111) |
| EN1, EN2 | Complementary enable inputs | Both must be asserted (EN1=low, EN2=high) to activate switching; supports gating |
| LE | Latch-enable input | Edge-triggered latch captures address bits; decouples address stability from switching timing |
| V− | Negative analog supply | Connect to GND for single-supply use; sets lower analog signal limit (V−) |
| GND | Digital ground reference | Reference for logic inputs only; isolated from analog signal path and V− |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - eliminates level-shifting in ±5V or +12V systems |
| Break-before-make switching | 4ns min interval prevents momentary shorting during channel transitions - essential for fault-tolerant routing |
| Address latching | LE input captures address bits asynchronously - allows stable switching even with noisy or slow address buses |
| TTL/CMOS logic compatibility | 0.8V/2.4V thresholds work directly with microcontrollers and FPGAs at +5V or ±5V supplies |
| Low power consumption | <1µW quiescent supply current - extends battery life in portable instrumentation |
| ESD robustness | >2kV HBM per Method 3015.7 - reduces field failure risk in handling and assembly |
Applications

Use Value: 0.025% THD preserves audio fidelity; 75Ω on-resistance at ±5V minimizes insertion loss in 600Ω audio paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG708BRUZ | 8-channel mux, 4.5Ω RON, +1.8V to +5.5V supply, no address latching or dual enable | Lower voltage operation but lacks LE/EN1/EN2 control architecture - requires external logic for gated addressing | Choose for ultra-low RON and sub-2V systems where latch/enable features are unnecessary |
| TS5A3159DCKR | Single SPDT, 0.75Ω RON, +1.65V to +5.5V, no address decoding - discrete switch per channel | Requires 8 separate control lines vs. 3 address + 2 enable lines; better for distributed switching, not centralized muxing | Choose when minimizing on-resistance is critical and board space permits discrete layout |
Compared with ADG708BRUZ and TS5A3159DCKR, the MAX4530CWP+ uniquely integrates address latching and dual enable logic in a single 8:1 configuration - reducing control-line count and eliminating external decode logic required by alternatives.

FAQ
What is the operating temperature range for the MAX4530CWP+?
The MAX4530CWP+ is specified for commercial-grade operation from 0°C to +70°C. This range is validated per the device's ordering information and electrical characteristics tables, and applies to all performance parameters including on-resistance, leakage, and switching times under both single- and dual-supply conditions.
Does the MAX4530CWP+ support single-supply operation?
Yes, the MAX4530CWP+ operates from a single +2V to +12V supply when V− is tied to GND. In this mode, analog signals swing from 0V to V+, and logic thresholds remain compatible with TTL/CMOS drivers - confirmed in the "ELECTRICAL CHARACTERISTICS-Single +5V Supply" section of the datasheet.
How does the latch-enable (LE) function improve system design with the MAX4530CWP+?
The LE input on the MAX4530CWP+ captures and holds address bits (ADDA/ADDB/ADDC) on its rising edge, decoupling address bus timing from switching action. This allows microcontrollers with slow or shared address buses to set addresses asynchronously, then trigger clean channel changes - eliminating glitches caused by address skew during transitions.
What is the maximum allowable analog signal range for the MAX4530CWP+?
The MAX4530CWP+ supports rail-to-rail analog signals from V− to V+. With ±5V supplies, this means −5V to +5V; with +12V/V− = GND, it is 0V to +12V. This range is guaranteed across the full temperature range and is limited only by the absolute maximum ratings (V− −0.3V to V+ +0.3V).
Is the MAX4530CWP+ pin-compatible with industry-standard logic devices?
Yes, the MAX4530CWP+ is explicitly designed to be pin-compatible with the 74HC4351 multiplexer. This compatibility enables drop-in replacement in legacy designs using that logic-family mux, preserving PCB layout while upgrading to superior analog performance including lower leakage, rail-to-rail operation, and integrated enable logic.
