Product details
Overview
MAX308C/D from Maxim Integrated is a precision single-ended 1-of-8 CMOS analog multiplexer with ≤100Ω on-resistance, <5Ω channel-to-channel on-resistance matching, and <10pC charge injection. It operates from +5V to +30V single supply or ±5V to ±20V dual supplies and is used in sample-and-hold circuits, automatic test equipment, and military radio signal routing.
For engineers reviewing the MAX308C/D datasheet, MAX308C/D pinout, MAX308C/D application, or MAX308C/D equivalent, this page delivers verified electrical parameters, package mapping to 16-pin DIP/SO/TSSOP, truth-table–validated switching behavior, and direct upgrade path information for DG408/DG508A replacements.
Technical Context
The MAX308C/D implements CMOS decode logic with three address inputs (A0–A2) and an active-low enable (EN) to select one of eight bidirectional analog channels (NO1–NO8) to the common terminal (COM). Its silicon-gate process ensures rail-to-rail analog signal handling up to ±20V with flat on-resistance (≤7Ω variation across ±10V range).
Switching is TTL/CMOS-compatible with input thresholds of VAL ≤ 0.8V and VAH ≥ 2.4V. Enable-controlled break-before-make timing (115–450ns) and low off-leakage (<5nA NO-off at +85°C) support high-accuracy sampling in battery-operated and military-grade systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG408DN | Higher on-resistance (120Ω typ), no guaranteed flatness spec, 25pC charge injection | Limited to non-critical industrial signal routing; not recommended for precision S/H | Select MAX308C/D where channel matching or low charge injection is required |

FAQ
What is the maximum analog signal range supported by the MAX308C/D?
The MAX308C/D supports an analog signal range of ±20V with dual supplies (±5V to ±20V) or 0V to +30V with single supply (+5V to +30V). This rail-to-rail capability allows full utilization of the supply rails without signal clipping, making it ideal for high-dynamic-range applications like military radios and test instrumentation where signal fidelity is critical. The device maintains specified on-resistance flatness across this entire range.
Does the MAX308C/D require external level-shifting when interfaced with 3.3V microcontrollers?
No, the MAX308C/D does not require external level-shifting when used with 3.3V microcontrollers. Its digital inputs are TTL/CMOS-compatible with logic thresholds defined as VAL ≤ 0.8V (low) and VAH ≥ 2.4V (high), ensuring reliable recognition of 3.3V logic levels. The internal CMOS input structure also minimizes loading, preserving signal integrity without additional buffering components.
How does the MAX308C/D compare to the DG408 in terms of on-resistance matching?
The MAX308C/D guarantees on-resistance matching of <5Ω between channels, whereas the DG408 specifies only typical matching of ~10Ω with no maximum limit. This tighter matching directly improves accuracy in ratiometric measurements and multi-channel calibration routines. The MAX308C/D achieves this through Maxim's improved 44V silicon-gate process, making it a documented plug-in upgrade for DG408-based designs where channel uniformity is essential.
Is the MAX308C/D suitable for battery-powered applications?
Yes, the MAX308C/D is well-suited for battery-powered applications due to its low power consumption (<300µW typical) and ability to operate down to +5V single supply. Its low NO-off leakage current (<5nA at +85°C) prevents signal degradation in high-impedance sampling nodes, extending effective battery life in portable test gear and handheld instrumentation. The device also supports unbalanced supplies (e.g., +24V/−5V), offering flexibility in mixed-power-system designs.
What package options are available for the MAX308C/D?
The MAX308C/D is offered in three standard packages: 16-pin plastic DIP (MAX308CPE), 16-pin narrow SO (MAX308CSE), and 16-pin TSSOP (MAX308CUE). All share identical pinout, electrical specifications, and 0°C to +70°C operating temperature range. The DIP variant suits prototyping and through-hole assembly, while SO and TSSOP support high-density PCB layouts in production systems.
