Product details
Overview
DG408DJ from Maxim Integrated is a precision 1-of-8 CMOS analog multiplexer/demultiplexer designed for bidirectional signal routing in high-fidelity data-acquisition and test systems. It delivers guaranteed 100Ω max on-resistance, 8Ω max channel-to-channel matching, 15pC max charge injection, and operates across -40°C to +85°C with ±5V to ±20V dual supplies or +5V to +30V single supply - enabling robust performance in industrial instrumentation and guidance control.
For engineers reviewing the DG408DJ datasheet, DG408DJ pinout, DG408DJ application, or DG408DJ equivalent, this page provides verified electrical specifications, validated package mapping to 16-pin plastic DIP, confirmed thermal operating range, and real-world design context for signal integrity-critical analog switching tasks.
Technical Context
The DG408DJ implements a fully decoded 3-bit address logic (A0/A1/A2) with active-low enable (EN), supporting rail-to-rail analog signal handling up to ±20V. Its CMOS transmission-gate architecture ensures symmetrical on-resistance and low distortion across all eight channels (S1–S8 to D).
It features guaranteed dynamic parameters including 100ns typical enable turn-on time (tON(EN)), 150ns typical transition time (tTRANS), and 75ns typical break-before-make interval (tOPEN), all specified over full temperature and supply ranges - critical for glitch-free channel switching in sample-and-hold and communications systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (rDS(ON)) | 100Ω max at TA = -40°C to +85°C - ensures minimal signal attenuation and gain error in precision measurement paths. |
| On-Resistance Matching | 8Ω max between any two channels - enables accurate differential measurements and multi-channel calibration without correction. |
| Charge Injection | 15pC max - limits voltage step error in sample-and-hold circuits, preserving DC accuracy after switching. |
| Analog Signal Range | ±10V min with ±15V supplies - supports full-scale operation across industrial sensor interfaces and audio line-level signals. |
| Off-Leakage Current | 5nA max at +85°C - maintains high-impedance isolation in high-resolution ADC front-ends and battery-powered systems. |
| Supply Range | +5V to +30V single or ±5V to ±20V dual - allows flexible integration into legacy and modern power architectures without level-shifting. |
| ESD Protection | >2000V per MIL-STD-883 Method 3015.7 - ensures reliability during board handling and system integration in manufacturing environments. |
Pinout & Package
Package: 16-pin plastic DIP (P16-2), through-hole mount, 0.300" wide body, compatible with standard IC sockets and wave-solder processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15, 16 | A0, A1, A2 | 3-bit binary address inputs selecting one of eight analog channels (S1–S8); TTL/CMOS compatible thresholds (VAL ≤ 0.8V, VAH ≥ 2.4V). |
| 2 | EN | Active-low enable controlling global switch conduction; when high, all channels are open-circuit regardless of address state. |
| 3 | V- | Negative supply rail input; must be connected for dual-supply operation or tied to GND for single-supply use. |
| 4–7 | S1–S4 | Bidirectional analog channel inputs/outputs; electrically identical to S5–S8 in function and specification. |
| 8 | D | Common bidirectional analog terminal - serves as output in mux mode or input in demux mode. |
| 9–12 | S8–S5 | Remaining four bidirectional analog channel terminals; numbered in reverse order for PCB layout symmetry in DIP package. |
| 13 | V+ | Positive supply rail input; supports up to +30V in single-supply configuration or +20V in dual-supply mode. |
| 14 | GND | Ground reference for logic interface and internal biasing; separate from analog signal ground but must share common reference for noise control. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V- to V+ without clipping - essential for unipolar/bipolar sensor outputs and DAC-driven actuator control. |
| Guaranteed low charge injection (15pC) | Minimizes hold-step error in sample-and-hold amplifiers, enabling sub-12-bit accuracy without post-switching settling delay. |
| Pin-compatible upgrade path | Direct replacement for legacy DG408 devices without PCB modification - preserves existing designs while improving matching and flatness. |
| Low power consumption (1.25mW max) | Reduces thermal drift and self-heating effects in densely packed instrumentation modules and portable test equipment. |
| Input leakage <5nA at +85°C | Prevents signal corruption in high-impedance sources (e.g., piezoelectric sensors, pH electrodes) across extended industrial temperature range. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRZ | 16-pin SOIC, 100Ω max rDS(ON), but only rated for -40°C to +85°C with 125Ω max on-resistance and no guaranteed matching spec. | Lacks guaranteed 8Ω channel matching and 15pC charge injection - less suitable for precision metrology or multi-channel calibration. | Select ADG408BRZ only if SOIC footprint is mandatory and matching/flatness requirements are relaxed. |
| MAX4617CSE+ | 8-channel mux in 16-pin SO, 60Ω max rDS(ON), but limited to +5V to +15V single supply and no dual-supply support. | Cannot replace DG408DJ in ±15V systems or rail-to-rail bipolar signal paths - requires redesign of power architecture. | Choose MAX4617CSE+ only for low-voltage, single-supply embedded applications where supply flexibility is not required. |
Compared with ADG408BRZ and MAX4617CSE+, the DG408DJ uniquely combines guaranteed channel matching, dual-supply operation up to ±20V, and industrial temperature range in a through-hole DIP package - making it irreplaceable for legacy-compatible, high-accuracy analog routing where signal integrity and mechanical robustness are non-negotiable.

FAQ
What is the maximum supply voltage rating for DG408DJ?
The DG408DJ supports +5V to +30V single supply or ±5V to ±20V dual supplies. Absolute maximum ratings specify V+ up to 44V referenced to V-, and continuous power dissipation is 842mW at +70°C in the 16-pin plastic DIP package. Exceeding these limits risks permanent damage, and operation above ±20V dual or +30V single supply is not characterized or guaranteed.
Does DG408DJ support rail-to-rail analog signal switching?
Yes, DG408DJ supports rail-to-rail analog signal handling - signals can swing from V- to V+ without clipping or increased distortion. This capability is explicitly confirmed in the datasheet's "Analog Signal Range" parameter (±10V min with ±15V supplies) and functional diagrams, enabling direct interfacing with op-amps, DACs, and sensors operating at supply rails.
Is DG408DJ pin-compatible with the original industry-standard DG408?
Yes, DG408DJ is a pin-compatible plug-in upgrade for the legacy DG408, sharing identical pinout, package dimensions, and logic interface behavior. The datasheet explicitly states "pin-compatible plug-in upgrades for the industry standard DG408 and DG409", and the pin description table confirms identical assignments for A0/A1/A2/EN/V+/V-/GND/D/S1–S8 across both generations.
What is the guaranteed on-resistance flatness specification for DG408DJ?
DG408DJ guarantees 9Ω max on-resistance flatness over its specified analog signal range - defined as the difference between maximum and minimum rDS(ON) measured at signal extremes (e.g., ±10V). This parameter is tested and guaranteed across the full -40°C to +85°C temperature range and ensures consistent gain and linearity when routing varying-amplitude signals.
How does DG408DJ perform in terms of off-isolation and crosstalk?
DG408DJ delivers -75dB minimum off-isolation and -92dB minimum crosstalk between input channels, both measured at 100kHz with RL = 1kΩ and CL = 1.0nF. These values are guaranteed over temperature and supply variations, ensuring high signal integrity in multi-channel acquisition systems where channel bleed-through must be minimized.
