Product details
Overview
MAX398CSE+TG55 from Maxim Integrated is an 8-channel precision CMOS analog multiplexer with <100Ω on-resistance, <6Ω channel-to-channel RON matching, and <5pC charge injection. It operates from +3V to +15V single supply or ±3V to ±8V dual supplies and is used in battery-operated data-acquisition systems requiring rail-to-rail signal handling and low leakage.
For engineers reviewing the MAX398CSE+TG55 datasheet, MAX398CSE+TG55 pinout, MAX398CSE+TG55 application, or MAX398CSE+TG55 equivalent, key selection criteria include on-resistance flatness (<11Ω), NO off-leakage current (<1nA at +85°C), COM off-leakage (<2.5nA), enable switching times (tON(EN) < 250ns), and pin compatibility with DG408/DG508A.
Technical Context
The MAX398CSE+TG55 implements a monolithic CMOS switch architecture with silicon-gate process optimization for low charge injection and ESD robustness (>2000V). Its address decoding logic (A0–A2) selects one of eight bidirectional analog channels to connect to the common COM terminal under EN control.
It supports rail-to-rail analog signal ranges up to ±4.5V with matched on-resistance across all channels and guaranteed flatness over the full signal swing. Logic inputs are TTL/CMOS-compatible, enabling direct interfacing with microcontrollers and FPGAs without level-shifting.
Key Specifications

| RON Matching | <6Ω max between channels - enables accurate ratiometric measurements and multi-channel calibration |
| Charge Injection | <5pC - reduces settling error in sample-and-hold circuits and high-impedance sensor interfaces |
| NO Off-Leakage | <1nA at +85°C - preserves accuracy in high-impedance, low-current applications like pH sensors |
| Supply Range | +3V to +15V single or ±3V to ±8V dual - supports portable, industrial, and military power architectures |
| Transition Time | <250ns - enables fast channel switching in automated test equipment and real-time signal routing |
| ESD Protection | >2000V HBM - enhances reliability during board assembly and field operation without external protection |
Pinout & Package
The MAX398CSE+TG55 is housed in a 16-pin narrow SOIC (SOIC-N) package with exposed pad (not connected per standard mounting; datasheet specifies EP connection to V+ only for QFN variants-SOIC-N has no exposed pad). Pin 1 is A0; pin 2 is A1; pin 3 is A2; pin 4–7 are NO1–NO4; pin 8 is COM; pin 9–12 are NO8–NO5; pin 13 is V+; pin 14 is GND; pin 15 is EN; pin 16 is V−.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A0) | Address Input LSB | Selects channel index bit 0; CMOS/TTL-compatible, drives internal decoder |
| 2 (A1) | Address Input Mid | Selects channel index bit 1; latched on EN assertion for stable channel selection |
| 3 (A2) | Address Input MSB | Selects channel index bit 2; completes 3-bit decode for 8-channel selection |
| 4–7 (NO1–NO4) | Analog Input/Output | Bidirectional passive terminals; support rail-to-rail signals up to ±4.5V |
| 8 (COM) | Common Analog Terminal | Single-pole, 8-throw switch output; connects to selected NOx under address/EN control |
| 9–12 (NO8–NO5) | Analog Input/Output | Bidirectional passive terminals; identical electrical specs to NO1–NO4 |
| 13 (V+) | Positive Supply | Accepts +3V to +15V; powers internal logic and switch driver circuitry |
| 14 (GND) | Ground Reference | Logic and analog reference node; must be low-impedance for noise immunity |
| 15 (EN) | Enable Control | Active-high digital input; disables all switches when low, preventing signal coupling |
| 16 (V−) | Negative Supply | Accepts −3V to −8V in dual-supply mode; tied to GND for single-supply operation |
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 |
|---|---|---|---|
| DG408DN | Higher on-resistance (120Ω typ), no guaranteed RON matching, no charge injection spec | Lacks precision specs needed for high-resolution data acquisition; suitable only for general-purpose routing | Choose DG408DN only if cost sensitivity outweighs precision requirements and leakage tolerance is relaxed |
| ADG1408BRUZ | Lower on-resistance (4.7Ω), higher supply voltage limit (+33V), but higher charge injection (12pC) | Better for high-voltage industrial I/O, less suitable for low-error S/H or high-Z sensor front-ends | Select ADG1408BRUZ when voltage range or on-resistance dominates; prefer MAX398CSE+TG55 for low-charge-injection critical paths |
Compared with DG408DN and ADG1408BRUZ, the MAX398CSE+TG55 uniquely balances ultra-low charge injection (<5pC), tight RON matching (<6Ω), and industry-standard pinout-making it optimal for precision, low-power, and drop-in upgrade scenarios where signal integrity and layout continuity are essential.

FAQ
What supply voltages does the MAX398CSE+TG55 support?
The MAX398CSE+TG55 operates from a single +3V to +15V supply or bipolar ±3V to ±8V supplies. When using single supply, V− must be connected to GND. The device maintains specified performance-including on-resistance, leakage, and switching speed-across this full range. For example, at +3V supply, on-resistance rises to 425Ω (typ), while at ±5V it is 100Ω (typ); designers must verify signal range and timing margins for their specific VCC.
Is the MAX398CSE+TG55 pin-compatible with the DG408?
Yes, the MAX398CSE+TG55 is explicitly pin-compatible with the DG408, DG409, DG508A, and DG509A. Its 16-pin narrow SOIC footprint matches the DG408's pinout exactly: A0–A2, EN, COM, NO1–NO8, V+, GND, and V− occupy identical positions. This allows direct replacement in existing layouts without redesign, preserving signal integrity and mechanical fit.
What is the maximum analog signal range supported by the MAX398CSE+TG55?
The MAX398CSE+TG55 supports rail-to-rail analog signals from V− to V+. With ±5V supplies, the usable range is ±4.5V; with +5V single supply (V− = GND), it is 0V to 4.5V. This range is limited by internal protection diodes and remains flat across the span-ensuring consistent on-resistance and minimal distortion for precision applications such as sensor conditioning and audio routing.
How does the enable (EN) pin affect switching behavior in the MAX398CSE+TG55?
The EN pin is an active-high digital control that globally enables or disables all eight analog switches. When EN is low, all channels are open (high-impedance), isolating COM from all NOx terminals regardless of address inputs. When EN goes high, the selected channel (per A0–A2) connects within <250ns. Break-before-make timing is guaranteed at 40ns min, preventing momentary shorts during channel transitions.
What thermal and reliability specifications apply to the MAX398CSE+TG55?
The MAX398CSE+TG55 is rated for 0°C to +70°C operation (Commercial grade) and features >2000V HBM ESD protection. Leakage currents are fully tested at +85°C and guaranteed by correlation at +25°C. On-resistance flatness remains <11Ω over temperature, and supply current stays below 1µA across the range-supporting stable performance in uncontrolled ambient environments typical of industrial and portable equipment.
