Product details
Overview
DG408MY/PR-T from Maxim Integrated is a precision 1-of-8 CMOS analog multiplexer/demultiplexer designed for high-fidelity signal routing in demanding industrial and aerospace systems. It delivers guaranteed 100Ω max on-resistance, 8Ω max channel-to-channel matching, 15pC max charge injection, ±5V to ±20V dual-supply operation, and rail-to-rail analog signal handling up to ±15V - enabling accurate sampling in data-acquisition and test equipment.
For engineers reviewing the DG408MY/PR-T datasheet, DG408MY/PR-T pinout, DG408MY/PR-T application, or DG408MY/PR-T equivalent, this page provides verified electrical parameters, SO package terminal mapping, real-world use context for high-reliability analog switching, and validated alternative options with documented functional and thermal differences.
Technical Context
The DG408MY/PR-T implements a fully decoded 3-bit address logic (A0–A2) with active-low enable (EN), selecting one of eight bidirectional analog channels (S1–S8) to the common D terminal. Its CMOS transmission-gate architecture ensures symmetrical conduction and minimal signal distortion across the full analog range.
It operates over -55°C to +125°C with guaranteed leakage <5nA at +85°C, supports break-before-make timing (115ns min), and maintains flat on-resistance (9Ω max variation) across ±10V signal swing - critical for low-error multiplexed instrumentation front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (rDS(ON)) | 100Ω max - ensures minimal gain error and voltage drop in precision sensor or DAC output paths |
| On-Resistance Matching | 8Ω max - enables consistent channel gain scaling in multi-channel calibration systems |
| Charge Injection | 15pC max - limits voltage glitch and settling time in sample-and-hold circuits |
| Analog Signal Range | ±15V (dual supply) - supports full-range bipolar signals without clipping in industrial control I/O |
| Supply Voltage Range | ±5V to ±20V dual or +5V to +30V single - allows flexible power architecture integration |
| Off-Leakage Current | 5nA max at +85°C - preserves accuracy in high-impedance sensor multiplexing (e.g., thermocouples) |
| Enable Turn-On Time | 100ns typ - enables fast channel switching in automated test equipment scan sequences |
Pinout & Package
DG408MY/PR-T is housed in a 16-pin narrow SO (Small Outline) package per package code S16-5, with standard 1.27mm pitch and gull-wing leads. The package meets JEDEC MS-012AC and is rated for -55°C to +125°C operation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15, 16 | A0, A1, A2 | 3-bit binary address inputs controlling channel selection (S1–S8 → D) |
| 2 | EN | Active-low enable - disables all switches when high, preventing unintended conduction |
| 3 | V− | Negative supply rail - sets lower bound of analog signal range and bias for internal logic |
| 4–7 | S1–S4 | Bidirectional analog input channels - connect to sensors, transducers, or signal sources |
| 8 | D | Common bidirectional analog terminal - routes selected channel to ADC, amplifier, or DAC |
| 9–12 | S8–S5 | Bidirectional analog input channels - continuation of 8-channel set (S5–S8) |
| 13 | V+ | Positive supply rail - sets upper bound of analog signal range and powers internal circuitry |
| 14 | GND | Ground reference - required for single-supply operation and digital logic level referencing |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without distortion - essential for full-scale industrial sensor interfacing |
| TTL/CMOS-compatible digital inputs | Accepts 0.8V/2.4V logic thresholds - simplifies interface with microcontrollers and FPGAs without level-shifting |
| Guaranteed on-resistance flatness | 9Ω max variation across full ±10V signal range - minimizes gain nonlinearity in precision measurement paths |
| ESD protection >2000V | Complies with MIL-STD-883 Method 3015.7 - enhances robustness during handling and system integration |
| Low power consumption | 1.25mW max - reduces thermal drift and enables use in power-constrained embedded modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRUZ | 8-channel mux with 75Ω max rDS(ON), 25pC max charge injection, -40°C to +85°C rating | Lacks extended temperature support and tighter matching specs; suitable for commercial-grade instrumentation | Select ADG408BRUZ only if operating ambient stays ≤+85°C and 8Ω matching is not required for calibration stability |
| MAX4617ESA+ | 8-channel mux with 60Ω max rDS(ON), 10pC max charge injection, but limited to +5V to +36V single supply only | No dual-supply capability; cannot handle ±15V bipolar signals without external level-shifting | Choose MAX4617ESA+ only for single-supply, ultra-low-charge-injection applications where bipolar signal routing is unnecessary |
Compared with DG408MY/PR-T, ADG408BRUZ trades extended temperature and matching performance for broader commercial availability, while MAX4617ESA+ offers lower on-resistance and charge injection but sacrifices dual-supply flexibility - making DG408MY/PR-T uniquely suited for ruggedized, bipolar-signal, high-precision multiplexing.

FAQ
What is the maximum analog signal voltage range supported by DG408MY/PR-T?
DG408MY/PR-T supports an analog signal range from V− to V+, enabling rail-to-rail operation. With ±15V dual supplies, it handles ±15V signals; with +30V single supply (V− = GND), it supports 0V to +30V. The absolute maximum analog voltage is limited by the supply rails - never exceeding V− −0.3V or V+ +0.3V per absolute maximum ratings.
Does DG408MY/PR-T require external pull-up resistors on its address or enable pins?
No, DG408MY/PR-T does not require external pull-up resistors. Its digital inputs (A0, A1, A2, EN) are TTL/CMOS compatible with defined logic thresholds (VAL ≤ 0.8V, VAH ≥ 2.4V) and exhibit low input current (±1.0µA max), allowing direct connection to microcontroller GPIOs or FPGA outputs without additional biasing components.
How does the -55°C to +125°C rating of DG408MY/PR-T impact its leakage performance?
DG408MY/PR-T guarantees input off-leakage current ≤5nA at +85°C - a value confirmed by 100% testing at maximum hot temperature. While leakage increases with temperature, the -55°C to +125°C rating ensures parametric compliance across the full range, with typical off-leakage remaining below 0.01nA at -55°C and rising gradually to ≤5nA at +85°C per characterization data.
Is DG408MY/PR-T pin-compatible with the original industry-standard DG408?
Yes, DG408MY/PR-T is explicitly described as a pin-compatible plug-in upgrade for the industry-standard DG408. It shares identical pinout, footprint, and logic interface behavior - including A0/A1/A2 addressing and active-low EN - allowing direct replacement without PCB modification, provided the extended temperature and improved specifications meet system requirements.
What is the significance of guaranteed 9Ω on-resistance flatness in DG408MY/PR-T?
The 9Ω max on-resistance flatness specification means the difference between the highest and lowest rDS(ON) values measured across the full specified analog signal range (e.g., ±10V) is ≤9Ω. This ensures minimal gain variation as signal amplitude changes - critical for maintaining linearity in precision data-acquisition front-ends and reducing harmonic distortion in audio routing applications.
