Product details
Overview
MAX4051ACEE+TG05 from Maxim Integrated is an 8-channel CMOS analog multiplexer configured as a single-pole, eight-throw (SP8T) switch with rail-to-rail signal handling, ±5V dual-supply or +5V single-supply operation, 100Ω typical on-resistance, 0.1nA max off-leakage at +25°C, and TTL/CMOS logic compatibility - used in low-voltage data-acquisition systems for channel selection.
For engineers reviewing the MAX4051ACEE+TG05 datasheet, MAX4051ACEE+TG05 pinout, MAX4051ACEE+TG05 application, or MAX4051ACEE+TG05 equivalent, key selection criteria include guaranteed on-resistance match (≤6Ω), low charge injection (≤10pC), high off-isolation (<–90dB), and QSOP-16 package compatibility with space-constrained portable instrumentation designs.
Technical Context
The MAX4051ACEE+TG05 implements a CMOS transmission-gate architecture with independent digital address decoding (ADDA/ADDB/ADDC) and global inhibit (INH) control, enabling precise selection of one of eight analog inputs (NO0–NO7) to the common terminal (COM). Its internal logic-level translators isolate digital control signals from analog supply domains (V+, V−, GND).
It supports bipolar supplies from ±2.7V to ±8V or single supplies from +2.7V to +16V, with analog signal range spanning rail-to-rail (V− to V+). All NO/COM terminals are bidirectional and electrically interchangeable, with no intrinsic input/output assignment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V supplies - ensures minimal signal attenuation and voltage drop in precision analog paths |
| On-resistance match (∆RON) | 6Ω max (A-suffix) - enables accurate gain/offset matching across channels in multi-channel measurement systems |
| Off-leakage current | 0.1nA max at +25°C - preserves signal integrity in high-impedance sensor interfaces and battery-powered standby modes |
| Off-isolation | <–90dB at 100kHz (50Ω) - suppresses crosstalk between inactive channels in dense multiplexed signal routing |
| Supply range | ±2.7V to ±8V dual or +2.7V to +16V single - supports flexible power architecture in mixed-signal industrial and portable equipment |
| Logic thresholds | VIL = 0.8V, VIH = 2.4V at +5V supply - guarantees reliable TTL/CMOS interfacing without level-shifting circuitry |
| Charge injection | 10pC max - minimizes settling error and glitch-induced offset in sampled-data acquisition front-ends |
Pinout & Package
MAX4051ACEE+TG05 is housed in a 16-pin QSOP (Quarter-Size Outline Package) with 0.15mm lead pitch, 3.9mm × 4.9mm body, and exposed pad for thermal enhancement. It is RoHS-compliant and rated for 0°C to +70°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | NO0–NO7 (Normally Open) | Bidirectional analog switch terminals; any may serve as input or output; selected channel connects to COM when enabled |
| 3 | COM (Common) | Shared analog path terminal; routed to one selected NOx pin under address control; no ground reference required |
| 6 | INH (Inhibit) | Active-high global disable; forces all switches open regardless of address inputs - critical for safe power sequencing |
| 7 | V− | Negative analog supply; tied to GND for single-supply operation; sets lower rail for analog signal swing |
| 8 | GND | Digital ground reference only; no analog return path; isolates logic domain from analog signal paths |
| 9, 10, 11 | ADDA, ADDB, ADDC | 3-bit binary address inputs selecting one of eight NOx channels; ADDC not used in MAX4052/MAX4053 variants |
| 16 | V+ | Positive analog/digital supply; powers internal logic translators and switch gates; defines upper analog rail |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Drop-in replacement for legacy HC logic-based multiplexers without PCB redesign or layout changes |
| Rail-to-rail analog signal handling | Supports full V− to V+ dynamic range - eliminates clipping in ±5V op-amp signal chains and audio routing |
| Low on-resistance flatness | 10Ω max variation over full analog range - maintains consistent gain and linearity across signal amplitude |
| Break-before-make switching | 30ns min tOPEN at +25°C - prevents momentary shorting between channels during address transitions |
| Guaranteed leakage specs | 0.1nA off-leakage and 0.1nA on-leakage at +25°C - validated per production test, not design-only spec |
Applications
| Battery-Operated Instrumentation | Audio Signal Routing |
|---|---|
Use Scenario: Portable multimeter or handheld data logger sampling multiple sensor inputs (thermocouples, RTDs, strain gauges) with microamp-level bias currents. IC Role / Device Role / Timing Role: 8-channel analog multiplexer enabling sequential ADC sampling while maintaining high input impedance and low leakage. Use Value: 0.1nA off-leakage prevents sensor loading errors; 100Ω RON ensures <0.1% gain error in 100kΩ source impedance configurations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4051CSE+ | Same functionality, 16-pin SO package (5.3mm × 10.2mm), wider body, higher thermal resistance (8.70mW/°C derating) | Preferred where board real estate allows larger footprint and manual soldering is acceptable | Select for cost-sensitive industrial designs requiring SOIC compatibility and extended temperature validation (0°C to +70°C) |
| ADG1408BRUZ | 8-channel, ±15V max supply, 4.7Ω RON, 1pA off-leakage, but requires separate VDD/VSS and logic supply pins | Used in high-precision lab equipment demanding ultra-low leakage and higher voltage headroom | Choose when sub-picoamp leakage or >±8V analog range is mandatory; accept added supply complexity and larger 20-pin TSSOP |
Compared with MAX4051CSE+ and ADG1408BRUZ, MAX4051ACEE+TG05 offers optimal balance of QSOP space efficiency, A-grade matching (6Ω), and proven 0.1nA leakage performance at standard +5V/±5V rails - ideal for portable and embedded systems where size, consistency, and low-power standby matter most.

FAQ
What is the maximum analog signal voltage range supported by the MAX4051ACEE+TG05?
The MAX4051ACEE+TG05 supports rail-to-rail analog signals from V− to V+. With ±5V dual supplies, this equals –5V to +5V; with +5V single supply (V− = GND), it is 0V to +5V. Absolute maximum ratings allow V+ up to +17V and V− down to –17V, but functional analog range remains bounded by the applied supply rails.
Is the MAX4051ACEE+TG05 pin-compatible with the standard 74HC4051?
Yes, the MAX4051ACEE+TG05 is explicitly pin-compatible with the 74HC4051, sharing identical pin assignments for NO0–NO7, COM, ADDA–ADDC, INH, V+, V−, and GND in the 16-pin QSOP package. This enables direct substitution without PCB modification.
What does the 'A' suffix in MAX4051ACEE+TG05 indicate?
The 'A' suffix denotes the enhanced performance grade: fully characterized for on-resistance match (≤6Ω), on-resistance flatness, and low leakage (0.1nA off-leakage at +25°C). Non-A parts (e.g., MAX4051CE) specify looser match (12Ω) and higher leakage (1nA).
Can the MAX4051ACEE+TG05 operate from a +3.3V single supply?
Yes, the MAX4051ACEE+TG05 operates from +2.7V to +16V single supply. At +3.3V, typical on-resistance rises to ~250Ω (vs. 100Ω at ±5V), and switching times increase, but all logic thresholds and leakage specs remain valid - confirmed in the +3V electrical characteristics tables.
How is channel selection controlled on the MAX4051ACEE+TG05?
Channel selection uses three binary address inputs: ADDA (LSB), ADDB, and ADDC (MSB). A 3-bit code (000–111) selects NO0 through NO7 to connect to COM. The INH pin overrides addressing: when high, all switches open regardless of address state.
