Product details
Overview
DG407DJ+ from Maxim Integrated is a dual 8-channel CMOS analog multiplexer/demultiplexer designed for bidirectional signal routing in precision data-acquisition and test systems. It features guaranteed on-resistance matching ≤8Ω, flatness ≤9Ω, low charge injection ≤15pC, max on-resistance of 100Ω, and operates from ±4.5V to ±20V dual supplies or +5V to +30V single supply - enabling rail-to-rail analog signal handling in guidance and control systems.
For engineers reviewing the DG407DJ+ datasheet, DG407DJ+ pinout, DG407DJ+ application, or DG407DJ+ equivalent, key selection considerations include channel matching tolerance, leakage performance at +85°C (≤5nA), enable timing (tON(EN) ≤ 600ns), dual-supply flexibility, and compatibility with TTL/CMOS logic interfaces.
Technical Context
The DG407DJ+ implements a fully differential dual-8-channel architecture with independent address decoding (A0–A2) and shared enable (EN) per section. Each 8-channel block routes analog signals bidirectionally between common outputs DA/DB and inputs S1A–S8A / S1B–S8B, supporting break-before-make switching with tOPEN ≤ 450ns.
Its CMOS transmission-gate design ensures rail-to-rail signal swing, low power consumption (≤1.25mW), and ESD robustness (>2000V per MIL-STD-883 Method 3015.7). Analog performance is specified across -40°C to +85°C, with leakage and on-resistance validated over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(ON)) | 100Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths |
| On-Resistance Matching | 8Ω max - guarantees consistent gain and offset across channels in multi-sensor acquisition |
| On-Resistance Flatness | 9Ω max - maintains linearity over full ±10V analog input range |
| Charge Injection | 15pC max - limits sampling error in high-resolution SAR ADC front-ends |
| Input Leakage (T = +85°C) | 5nA max - preserves accuracy in high-impedance sensor interfaces and sample-and-hold circuits |
| Supply Range | ±4.5V to ±20V dual or +5V to +30V single - supports industrial and automotive power architectures |
| Enable Turn-On Time | 600ns max - enables fast channel switching in real-time test equipment |
Pinout & Package
DG407DJ+ is housed in a 28-pin plastic DIP package (0.600" wide), RoHS-compliant and lead-free (+ suffix), rated for -40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | V+, DB | Positive supply input and bidirectional output B - V+ powers internal logic and switches; DB serves as common output for second 8-channel bank |
| 3, 13, 14 | N.C. | No internal connection - must be left unconnected; not usable as grounds or bypass nodes |
| 4–11 | S1B–S8B | Bidirectional analog inputs for second channel bank - support symmetric signal routing without polarity constraints |
| 12 | GND | Analog/digital ground reference - requires low-impedance connection to minimize crosstalk and noise coupling |
| 15–17 | A0, A1, A2 | Binary address inputs for channel selection - decode 0–7 for each bank; A3 is not present on DG407 (vs. DG406) |
| 18 | EN | Active-low enable - disables all switches when high; critical for power sequencing and system-level isolation |
| 19–26 | S1A–S8A | Bidirectional analog inputs for first channel bank - electrically identical to S1B–S8B; enables true differential muxing |
| 27 | V- | Negative supply input - sets lower rail for bipolar operation; must be connected even in single-supply mode (tied to GND) |
| 28 | DA | Bidirectional output A - common path for first 8-channel bank; shares no internal connection with DB |
Key Features
| Feature | Design Value |
|---|---|
| Pin-compatible upgrade | Direct replacement for legacy DG407 - no PCB redesign required; retains identical footprint and pin function |
| Rail-to-rail signal handling | Supports analog inputs from V- to V+ - eliminates level-shifting in ±15V instrumentation and audio routing |
| TTL/CMOS-compatible control | Accepts 0.8V/2.4V logic thresholds - interoperates with microcontrollers, FPGAs, and legacy digital systems without interface buffers |
| Guaranteed low leakage | ≤5nA off-leakage at +85°C - sustains accuracy in thermocouple, strain gauge, and medical sensor front-ends |
| ESD protection | >2000V per MIL-STD-883 Method 3015.7 - enhances reliability in benchtop test equipment subject to frequent handling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG407BRZ | 16-bit compatible logic thresholds; slightly higher RDS(ON) (120Ω typ); same 28-SO package but different pinout | Preferred in mixed-signal FPGA designs requiring tighter logic-level alignment with 3.3V I/O banks | Select ADG407BRZ only if board layout accommodates SOIC-28 and logic interface matches; not pin-compatible with DG407DJ+ |
| MAX4617CSE+ | Dual SPST configuration (not 8×2); lower on-resistance (60Ω max); operates up to +70°C only | Suitable for discrete channel enable/disable in modular test fixtures where full mux functionality is unnecessary | Choose MAX4617CSE+ when simplifying control logic and reducing channel count; not a functional or pin-for-pin substitute |
Compared with ADG407BRZ and MAX4617CSE+, the DG407DJ+ uniquely delivers guaranteed -40°C to +85°C operation, 8Ω channel matching, and true dual-8-channel architecture in a through-hole DIP package - making it optimal for ruggedized, field-deployable instrumentation where thermal stability and mechanical reliability are primary constraints.

FAQ
What is the operating temperature range for DG407DJ+?
The DG407DJ+ is rated for operation from -40°C to +85°C. This extended industrial temperature range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet, and applies specifically to the "DJ+" variant with 28-pin plastic DIP packaging. The "C" grade (e.g., DG407CJ+) is limited to 0°C to +70°C.
Does DG407DJ+ support single-supply operation?
Yes, DG407DJ+ supports single-supply operation from +5V to +30V. In this configuration, V- must be connected to GND. The datasheet explicitly states this capability in the General Description and Applications Information sections, and electrical characteristics are provided for both dual-supply (±4.5V to ±20V) and single-supply (V+ = 12V, V- = 0V) conditions.
Is DG407DJ+ pin-compatible with the original DG407?
Yes, DG407DJ+ is a pin-compatible plug-in upgrade for the industry-standard DG407, as stated verbatim in the General Description and Features sections. Pin functions, spacing, and package outline (28-pin DIP) are identical, enabling direct replacement without PCB modification. This compatibility is guaranteed by Maxim and applies specifically to the DJ+ variant.
What is the maximum allowable analog signal range for DG407DJ+?
The maximum analog signal range for DG407DJ+ is from V- to V+, as confirmed in the Electrical Characteristics table under "Analog Signal Range" (VANALOG), which specifies ±15V for dual-supply operation and 0V to +12V for single-supply. This rail-to-rail capability is enabled by its CMOS transmission-gate architecture and is validated across the full -40°C to +85°C temperature range.
How does DG407DJ+ handle power-supply sequencing?
DG407DJ+ requires proper sequencing: V+ must be applied first, then V-, followed by logic inputs and analog signals. This is mandated in the Applications Information section to prevent latch-up or damage. If sequencing cannot be guaranteed, external blocking diodes (as shown in Figure 1) are recommended - though they reduce the effective analog range by ±1V while preserving on-resistance and leakage specs.
