Product details
Overview
MAX4051EPE 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 (A-suffix variant), and TTL/CMOS logic compatibility-used in battery-powered data-acquisition systems for sensor channel selection.
For engineers reviewing the MAX4051EPE datasheet, MAX4051EPE pinout, MAX4051EPE application, or MAX4051EPE equivalent, key selection criteria include guaranteed on-resistance match (6Ω), low charge injection (2pC), high off-isolation (<–90dB), and EPE-package thermal performance across –40°C to +85°C industrial temperature range.
Technical Context
The MAX4051EPE implements a single 8:1 analog multiplexer using complementary MOSFET switch pairs per channel, driven by decoded ADDA/ADDB/ADDC address inputs and controlled by INH. Its internal logic-level translators isolate digital control signals from analog supplies while enabling operation across wide voltage ranges.
It features break-before-make switching (30ns typical), low distortion (<0.04% at 600Ω), and symmetrical analog conduction-NO/COM pins are fully bidirectional with no intrinsic input/output designation, supporting flexible signal routing in both directions without performance penalty.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | Dual: ±2.7V to ±8V; Single: +2.7V to +16V - enables direct integration into mixed-voltage systems including battery-powered and industrial rails. |
| On-Resistance (RON) | 100Ω max at ±5V - ensures minimal signal attenuation and gain error in precision measurement paths. |
| On-Resistance Match | 6Ω max (MAX4051A series) - critical for ratiometric measurements and channel-to-channel calibration stability. |
| Off-Leakage Current | 0.1nA max at +25°C - preserves high-impedance sensor node integrity and reduces offset drift in µV-level front-ends. |
| Off-Isolation | <–90dB at 100kHz (50Ω) - prevents crosstalk between inactive channels in multi-signal routing applications. |
| Charge Injection | 2pC max - minimizes voltage glitch on sampled-hold capacitors, essential for ADC interface accuracy. |
| Logic Thresholds | VIL = 0.8V, VIH = 2.4V at +5V supply - guarantees reliable TTL/CMOS interfacing without level-shifting circuitry. |
Pinout & Package
MAX4051EPE is supplied in a 16-pin plastic DIP (Dual In-line Package) with 0.3-inch body width, through-hole mounting, and operating temperature range of –40°C to +85°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | NO0–NO7 | Eight normally-open analog terminals - interchangeable as inputs or outputs; each connects to COM when selected. |
| 3 | COM | Common analog terminal - bidirectional signal path shared across all eight channels; no ground reference required. |
| 6 | INH | Digital inhibit input - logic high disables all switches; active-low enable simplifies system-level power gating. |
| 7 | V− | Negative analog supply - tied to GND for single-supply use; sets lower rail for rail-to-rail analog swing. |
| 8 | GND | Digital ground reference - isolated from analog signal path; provides logic supply return only. |
| 9, 10, 11 | ADDA, ADDB, ADDC | 3-bit binary address inputs - decode one of eight channels; CMOS-compatible thresholds eliminate external biasing. |
| 16 | V+ | Positive analog/digital supply - powers internal logic translators and switch drivers; defines upper analog voltage limit. |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE WITH 74HC4051 | Direct drop-in replacement for legacy HC4051 designs-no PCB or firmware changes required for upgrade path. |
| RAIL-TO-RAIL ANALOG SIGNAL HANDLING | Supports full V− to V+ voltage range on all NO/COM pins-enables seamless integration with op-amps and ADCs operating at supply rails. |
| LOW ON-RESISTANCE FLATNESS | 10Ω max variation over full analog signal range-maintains consistent gain and linearity across input voltage span. |
| BREAK-BEFORE-MAKE SWITCHING | 30ns typical delay-prevents momentary shorting between channels during address transitions, critical for fault-tolerant routing. |
| GUARANTEED LEAKAGE PERFORMANCE | 0.1nA off-leakage tested at hot temperature and correlated at +25°C-ensures production yield and long-term reliability in low-current applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BNZ | 8-channel CMOS mux; 100Ω RON at ±5V; 0.5nA off-leakage at +25°C; SOIC-16 package. | Higher leakage limits suitability for sub-µV precision systems; lacks A-suffix matched RON spec. | Select when SOIC footprint is required and 0.5nA leakage is acceptable in target signal chain. |
| 74HC4051D | Pin-compatible 8:1 mux; 120Ω RON at +4.5V; 100nA off-leakage at +25°C; no guaranteed RON match or flatness. | Not suitable for precision ratiometric or low-leakage applications; intended for general-purpose digital control. | Select only for cost-sensitive non-precision digital routing where leakage and matching are not design-critical. |
Compared with ADG408BNZ and 74HC4051D, MAX4051EPE delivers superior leakage control (0.1nA vs. 0.5nA/100nA) and guaranteed 6Ω RON matching-making it the preferred choice for high-accuracy, low-drift instrumentation requiring channel consistency and long-term stability.

FAQ
What is the operating temperature range for MAX4051EPE?
The MAX4051EPE is rated for operation from –40°C to +85°C. This industrial-grade temperature range is confirmed in the Ordering Information table, where "MAX4051EPE" is explicitly listed under the "–40°C to +85°C" temperature column and 16-pin plastic DIP (EPE) package. It meets requirements for deployment in harsh environments such as factory automation and outdoor instrumentation.
Does MAX4051EPE support single-supply operation?
Yes, MAX4051EPE supports single-supply operation from +2.7V to +16V with V− tied to GND. Electrical characteristics tables explicitly include "Single +5V Supply" and "Single +3V Supply" test conditions, and the Applications Information section confirms functionality down to +1.7V (though with degraded RON and timing). The device maintains rail-to-rail analog signal handling across this range.
What is the maximum on-resistance specification for MAX4051EPE at ±5V?
The maximum on-resistance for MAX4051EPE at ±5V is 100Ω, as specified in the "ELECTRICAL CHARACTERISTICS-Dual Supplies" table under RON parameter (TYP = 125Ω, MAX = 100Ω at TA = +25°C, V+ = 5V, V− = –5V, INO = 1mA, VCOM = ±3V). This value applies to the A-suffix family (MAX4051A), and MAX4051EPE is an A-suffix part per ordering code mapping.
How does the INH pin function on MAX4051EPE?
The INH (Inhibit) pin on MAX4051EPE is an active-high digital control input that disables all eight analog switches when driven logic high. When INH = V+, all NO–COM paths are opened regardless of address inputs. When INH = GND or V−, normal address-decoded switching resumes. This allows global channel disable for power saving or safety interlocks without altering address lines.
Is MAX4051EPE pin-compatible with the 74HC4051?
Yes, MAX4051EPE is pin-compatible with the industry-standard 74HC4051, as confirmed in the Features section: "Pin Compatible with Industry-Standard 74HC4051/74HC4052/74HC4053". Pin assignments (NO0–NO7, COM, ADDA–ADDC, INH, V+, V−, GND) match exactly, enabling direct substitution in existing layouts-provided supply and leakage requirements are verified.
