Product details
Overview
MAX4051ACPE from Maxim Integrated is an 8-channel CMOS analog multiplexer with rail-to-rail signal handling, ±2.7V to ±8V dual-supply or +2.7V to +16V single-supply operation, 100Ω typical on-resistance at ±5V, 0.1nA max off-leakage at +25°C, and TTL/CMOS logic compatibility-used in battery-powered data-acquisition systems for channel selection.
For engineers reviewing the MAX4051ACPE datasheet, MAX4051ACPE pinout, MAX4051ACPE application, or MAX4051ACPE equivalent, this page delivers verified electrical specs, package-validated pin functions, real-world use cases in low-voltage routing, and two confirmed alternative parts with documented differences in on-resistance matching and leakage performance.
Technical Context
The MAX4051ACPE implements a single 8:1 analog multiplexer using CMOS transmission-gate architecture with independent digital address decoding (ADDA/ADDB/ADDC) and global inhibit (INH). Its internal logic-level translators isolate digital control signals from analog supply rails (V+, V−), enabling robust operation across wide supply ranges.
All NOx and COM pins are bidirectional and electrically symmetric; no dedicated input/output assignment exists. The A-suffix guarantees matched on-resistance (≤6Ω), flat on-resistance (≤10Ω), and ultra-low leakage (0.1nA off / 0.1nA on at +25°C), distinguishing it from non-A variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 8-channel analog multiplexer (1-of-8 selector) |
| Supply Range | Dual: ±2.7V to ±8V; Single: +2.7V to +16V - supports portable and industrial rails |
| On-Resistance (RON) | 100Ω max at ±5V - ensures minimal signal attenuation in precision sensor interfaces |
| On-Resistance Match | 6Ω max between channels (A-suffix) - critical for gain-matching in multi-channel ADC front-ends |
| Off-Leakage Current | 0.1nA max at +25°C - preserves accuracy in high-impedance pH or thermocouple circuits |
| Logic Thresholds | VIL = 0.8V, VIH = 2.4V at +5V supply - ensures reliable TTL/CMOS interfacing without level shifters |
| Off-Isolation | <−90dB at 100kHz (50Ω) - prevents crosstalk between inactive channels in audio routing |
Pinout & Package
MAX4051ACPE is supplied in a 16-pin plastic DIP (Dual In-line Package) with 0.3-inch body width and through-hole mounting. Pin spacing is 0.1 inch; lead finish is matte tin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | NO0–NO7 | Normally open analog switch terminals - interchangeable as inputs or outputs; all support rail-to-rail voltage swing |
| 3 | COM | Common analog terminal - connects to selected NOx channel; bidirectional signal path |
| 6 | INH | Digital inhibit input - logic high disables all switches; tied to GND for normal operation |
| 7 | V− | Negative analog supply - grounded for single-supply use; sets lower analog signal limit |
| 8 | GND | Digital ground reference - separate from analog signal return; no current path to analog channels |
| 9, 10, 11 | ADDA, ADDB, ADDC | 3-bit binary address inputs - select one of eight NOx channels (000–111); CMOS/TTL compatible |
| 16 | V+ | Positive analog/digital supply - powers internal logic and switch gates; sets upper analog signal limit |
Key Features
| Feature | Design Value |
|---|---|
| Precision on-resistance matching | ≤6Ω channel-to-channel variation (A-suffix) - enables calibrated multi-channel sensor arrays without per-channel trimming |
| Rail-to-rail analog signal range | VCOM and VNO swing from V− to V+ - eliminates external biasing in ±5V or +3.3V systems |
| Ultra-low off-leakage | 0.1nA max at +25°C - maintains DC accuracy in >100MΩ source-impedance applications (e.g., piezoelectric sensors) |
| Break-before-make switching | 30ns min tOPEN at +5V - prevents momentary shorting during channel transitions in power-sensitive circuits |
| Low charge injection | 2pC max - minimizes voltage glitch on high-capacitance nodes (e.g., sample-and-hold capacitors) |
Applications
| Battery-Powered Data Acquisition | Audio Signal Routing |
|---|---|
Use Scenario: Multiplexing 8 thermistor or RTD inputs into a single ADC in handheld test equipment. IC Role / Device Role / Timing Role: Analog multiplexer selecting one sensor channel per conversion cycle; address lines driven by microcontroller GPIO.

IC Role / Device Role / Timing Role: Bidirectional analog switch matrix controlled by system MCU; INH used for mute function. Use Value: <−90dB off-isolation eliminates audible crosstalk; rail-to-rail swing preserves full dynamic range. |
| Low-Voltage Industrial Sensing | Communications Circuit Protection |
Use Scenario: Selecting between 8 pressure transducer outputs in a 3.3V IoT node with Li-ion battery supply. IC Role / Device Role / Timing Role: Low-voltage multiplexer operating from single +3.3V supply; ADDx lines driven by 3.3V logic. Use Value: Guaranteed operation down to +2.7V allows extended runtime near battery EOD; 6Ω RON match ensures consistent channel gain. | Use Scenario: Isolating RS-232 or CAN transceiver analog I/O paths during hot-plug events or fault conditions. IC Role / Device Role / Timing Role: Fail-safe analog switch activated by system supervisor to disconnect sensitive PHY pins. Use Value: 0.1nA leakage prevents false triggering of receiver thresholds; ±8V rating withstands transient surges up to ±7V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4051CPE | Non-A variant: 12Ω max on-resistance match, 1nA max off-leakage at +25°C | Lower precision; suitable for non-critical signal routing where cost is prioritized over matching | Select when leakage <1nA and RON match <12Ω meet system requirements |
| ADG1408BRUZ | 16V max supply, 4.7Ω typical RON, 1pA typical off-leakage, but requires external VDD/VSS decoupling | Higher precision and lower leakage, but not pin-compatible; needs PCB redesign | Choose for ultra-low-leakage designs where layout change is acceptable |
Compared with MAX4051CPE, the MAX4051ACPE delivers 2× tighter on-resistance matching and 10× lower off-leakage - critical for calibrated multi-sensor systems. Versus ADG1408BRUZ, it offers drop-in replacement capability in legacy DIP layouts but trades off ultimate leakage performance for mechanical compatibility.

FAQ
What is the maximum supply voltage rating for MAX4051ACPE?
The MAX4051ACPE supports dual supplies from ±2.7V to ±8V (V+ to V− ≤ 17V) or single supply from +2.7V to +16V. Absolute maximum ratings specify V+ to GND ≤ +17V and V− to GND ≥ −17V. Exceeding these may cause permanent damage. Operation at +16V single supply is validated per datasheet Electrical Characteristics tables.
Does MAX4051ACPE support rail-to-rail analog signal operation?
Yes, the MAX4051ACPE supports rail-to-rail analog signal operation: input and output voltages on COM and NOx pins can swing from V− to V+ under all valid supply conditions. This is confirmed in the General Description and Analog Signal Range specifications across dual and single-supply configurations.
What is the guaranteed on-resistance match specification for MAX4051ACPE?
The MAX4051ACPE guarantees a maximum on-resistance match (∆RON) of 6Ω between any two channels at TA = +25°C with ±5V supplies. This is explicitly stated in the Features section and Electrical Characteristics table under "COM–NO On-Resistance Match Between Channels" for A-suffix parts.
Can MAX4051ACPE be used with a +3.3V single supply?
Yes, the MAX4051ACPE operates with a +3.3V single supply (V− = GND). Datasheet Electrical Characteristics for Single +3V Supply confirm functionality at V+ = +3.0V to +3.6V, with RON = 250Ω to 700Ω and leakage currents within spec. Logic thresholds remain compatible with 3.3V CMOS levels.
Is MAX4051ACPE pin-compatible with industry-standard 74HC4051?
Yes, the MAX4051ACPE is pin-compatible with the 74HC4051 in 16-pin DIP, SO, and QSOP packages. This is explicitly stated in the Features section ("Pin Compatible with Industry-Standard 74HC4051/74HC4052/74HC4053") and confirmed by identical pin numbering and functions in the Pin Configurations diagram.
