Product details
Overview
MAX308ESE from Maxim Integrated is a precision single-ended 1-of-8 CMOS analog multiplexer with on-resistance <100Ω, on-resistance matching <5Ω between channels, and guaranteed flatness of ≤7Ω over ±10V signal range. It operates from +5V to +30V single supply or ±5V to ±20V dual supplies, features rail-to-rail signal handling, and is used in sample-and-hold circuits, automatic test equipment, and military radio signal routing.
For engineers reviewing the MAX308ESE datasheet, MAX308ESE pinout, MAX308ESE application, or MAX308ESE equivalent, key selection criteria include its -40°C to +85°C industrial temperature rating, 16-pin narrow SO package, low 5nA NO-off leakage at +85°C, and plug-in compatibility with DG408/DG508A legacy designs.
Technical Context
The MAX308ESE implements a CMOS decode logic architecture with three address inputs (A0–A2) and an active-low enable (EN), selecting one of eight bidirectional analog channels (NO1–NO8) to connect to the common terminal (COM). Its silicon-gate process ensures low charge injection (<10pC) and ESD protection >2000V.
It supports both unipolar and bipolar operation without external level-shifting: analog signals swing rail-to-rail (e.g., ±10V with ±15V supplies), while TTL/CMOS-compatible digital inputs (VAL ≤ 0.8V, VAH ≥ 2.4V) drive switching with sub-250ns transition time and break-before-make timing of 115–450ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | <100Ω max - ensures minimal signal attenuation and gain error in precision signal paths |
| On-Resistance Matching | <5Ω max - enables accurate channel-to-channel ratio matching in instrumentation and mux-based PGA designs |
| On-Resistance Flatness | <7Ω max over ±10V - maintains consistent gain and linearity across full analog input range |
| NO-Off Leakage | <5nA at +85°C - preserves accuracy in high-impedance sample-and-hold and sensor front-end applications |
| Charge Injection | <10pC - minimizes voltage glitch and settling error when switching capacitive loads (e.g., ADC input hold capacitors) |
| Supply Range | +5V to +30V single or ±5V to ±20V dual - supports wide-range industrial, military, and battery-backed systems |
| Transition Time | <250ns - enables fast channel switching in automated test and real-time signal routing |
Pinout & Package
MAX308ESE is housed in a 16-pin narrow SO (Small Outline) package, 3.9mm body width, with standard JEDEC MS-012AC footprint and gull-wing leads.
| Pin | Circuit Role | Design Meaning |

| 1, 2, 3 | A0, A1, A2 | Binary address inputs selecting one of eight NOx channels; CMOS/TTL compatible |
| 4–7, 9–12 | NO1–NO8 | Bidirectional analog channel terminals; each connects to COM when selected |
| 8 | COM | Common analog I/O node - serves as input or output depending on signal direction |
| 13 | V+ | Positive supply rail - accepts +5V to +30V (single) or up to +44V differential vs V− |
| 14 | GND | Ground reference for logic inputs and internal biasing; tied to V− in single-supply mode |
| 15 | V− | Negative supply rail - accepts 0V (single) or −5V to −20V (dual); substrate tied to V+ |
| 16 | EN | Active-low enable - disables all switches when high, reducing leakage and power consumption |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX308CSE | Same functionality and pinout, but rated for 0°C to +70°C only; lower temperature grade. | Suitable for commercial-grade systems where extended temperature operation is not required. | Select MAX308CSE only if ambient operating temperature stays within 0°C–70°C and cost sensitivity outweighs industrial reliability needs. |
| ADG408BRUZ | 8-channel single-ended CMOS mux; on-resistance ~100Ω but higher leakage (25nA @ +85°C) and no guaranteed flatness spec. | Lacks guaranteed RON flatness and tighter leakage specs - less suitable for precision sample-and-hold or military use. | Consider ADG408BRUZ only for non-critical general-purpose routing where leakage and linearity are secondary to availability or price. |
Compared with MAX308CSE, the MAX308ESE provides assured operation across -40°C to +85°C and matches tighter leakage and flatness specs; versus ADG408BRUZ, it delivers superior channel matching, lower charge injection, and guaranteed rail-to-rail performance essential for precision analog systems.

FAQ
What is the maximum analog signal range supported by the MAX308ESE?
The MAX308ESE supports rail-to-rail analog signals: up to ±10V with ±15V dual supplies, or 0V to +10V with +12V single supply. The exact range depends on supply voltages - for example, with ±20V supplies, the usable analog range extends to ±15V. This is specified in the Electrical Characteristics table under "Analog Signal Range" with test conditions including VCOM = ±10V and VNO = ±10V. The MAX308ESE maintains low on-resistance flatness across this full range.
Is the MAX308ESE pin-compatible with the DG408?
Yes, the MAX308ESE is a direct plug-in upgrade for the DG408, sharing identical pin configuration, logic interface, and functional behavior. The datasheet explicitly states "improved parts are plug-in upgrades for the industry-standard DG408, DG409, DG508A, and DG509A." No PCB layout changes are required when replacing DG408 with MAX308ESE, though users benefit from lower on-resistance, reduced charge injection, and enhanced ESD protection.
What is the guaranteed on-resistance matching specification for MAX308ESE?
The MAX308ESE guarantees on-resistance matching of less than 5Ω between any two channels across the full operating temperature range (-40°C to +85°C). This parameter (∆RON) is defined as RON(MAX) – RON(MIN) and is tested per the datasheet's Electrical Characteristics table. Tight matching ensures consistent gain and minimal channel-to-channel error in instrumentation amplifier and programmable gain applications using the MAX308ESE.
Does the MAX308ESE support single-supply operation?
Yes, the MAX308ESE operates from a single +5V to +30V supply, with V− connected to GND. In this configuration, it retains TTL/CMOS logic compatibility, rail-to-rail analog signal handling, and all key specifications including <100Ω on-resistance and <5nA NO-off leakage at +85°C. The datasheet confirms single-supply operation in both the General Description and Electrical Characteristics sections, with dedicated test conditions for V+ = +12V, V− = 0V.
What package type is used for the MAX308ESE?
The MAX308ESE is supplied in a 16-pin narrow SO (Small Outline) package, also referred to as SOIC-NB or 16-SO. It has a 3.9mm body width, 1.27mm lead pitch, and complies with JEDEC MS-012AC outline dimensions. This surface-mount package supports automated assembly and offers thermal and mechanical performance suitable for industrial and military applications - distinct from the plastic DIP (MAX308EPE) or CERDIP (MAX308EJE) variants.
