Product details
Overview
DG407BDJ-E3 from Vishay Siliconix is a dual 8-channel differential analog multiplexer IC designed to route one of eight differential input pairs to a common differential output in precision signal-path applications. It features 45 Ω on-resistance, 11 pC charge injection, 115 ns transition time, ±20 V dual-supply operation, and break-before-make switching-enabling high-fidelity audio routing and low-glitch data acquisition in medical instrumentation and ATE systems.
For engineers reviewing the DG407BDJ-E3 datasheet, DG407BDJ-E3 pinout, DG407BDJ-E3 application, or DG407BDJ-E3 equivalent, this page delivers verified specifications, SOIC-28 package mapping, functional truth table alignment, and validated alternative options for differential multiplexing in ±15 V or single 12 V systems.
Technical Context
The DG407BDJ-E3 implements a fully differential 8:1 × 2 architecture with independent S1a–S8a and S1b–S8b switch arrays, each controlled by a shared 3-bit binary address (A0–A2) and enable (EN). Its silicon-gate CMOS process supports rail-to-rail analog signal handling up to ±20 V while maintaining sub-5 nA off-leakage across temperature.
Break-before-make timing (tOPEN = 10–39 ns) prevents momentary shorting during channel transitions, and TTL-compatible digital inputs (VINH ≥ 2.4 V, VINL ≤ 0.8 V) ensure robust interfacing with microcontrollers and FPGAs without level-shifting in industrial embedded designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Dual 8:1 differential multiplexer - routes two matched analog paths simultaneously with identical on-resistance and timing. |
| On-resistance (RDS(on)) | 45 Ω typical at ±15 V - ensures minimal gain error and channel-to-channel mismatch in precision gain-setting circuits. |
| Charge injection | 11 pC - limits voltage glitch on high-impedance nodes (e.g., sample-and-hold inputs), critical for 14-bit+ ADC front-ends. |
| Transition time | 115 ns typical - supports >5 MHz multiplexed sampling rates in high-speed data acquisition systems. |
| Analog signal range | ±15 V full range - enables direct interface with industrial sensors and bipolar op-amp stages without external clamping. |
| Off isolation (OIRR) | −86 dB at 1 MHz - suppresses crosstalk between active and inactive differential channels in dense PCB layouts. |
| Supply range | ±5 V to ±20 V dual or 12 V single - simplifies power architecture in mixed-signal systems with shared rails. |
Pinout & Package
DG407BDJ-E3 is housed in a 28-pin wide-body SOIC (SO-28W) package per Vishay drawing 71268, with 0.406" body width, 0.334" lead span, and 1.27 mm pitch. Pin 1 is marked by a beveled corner; pins are arranged in two rows (1–14 top, 15–28 bottom), with GND at pin 9 and V− at pin 16.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply rail | Accepts +5 V to +20 V; powers internal level shifters and switch drivers for rail-to-rail analog conduction. |
| V− | Negative supply rail | Accepts −5 V to −20 V; defines lower analog signal limit and enables true bipolar operation. |
| GND | Ground reference | Logic ground return; decoupling capacitor must connect here to minimize digital noise coupling into analog paths. |
| EN | Enable control input | Active-high TTL-compatible signal; forces all switches OFF when low, enabling stacking of multiple DG407BDJ-E3 devices. |
| A0–A2 | Binary address inputs | Selects one of eight differential pairs (S1a/S1b through S8a/S8b); no internal pull-ups-requires external termination. |
| S1a–S8a | Differential input A terminals | Eight analog inputs for first polarity leg; each connects to Da output when selected via A0–A2 and EN. |
| S1b–S8b | Differential input B terminals | Eight complementary analog inputs; paired with S1a–S8a to form fully differential signal paths. |
| Da, Db | Differential outputs | Common output pair; maintains matched impedance and phase response essential for ADC driver interfaces. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 10–39 ns tOPEN prevents transient shorts during channel changes-critical for protecting sensitive downstream circuitry. |
| Rail-to-rail analog conduction | Supports signals from V− to V+ without clipping-enables direct connection to ±15 V op-amps and sensor bridges. |
| Low charge injection (11 pC) | Minimizes voltage step on sampled capacitors, reducing settling time and improving effective resolution in SAR ADC systems. |
| TTL-compatible control logic | Operates across full −40 °C to +85 °C range with VINH ≥ 2.4 V and VINL ≤ 0.8 V-eliminates need for level translators in MCU/FPGA interfaces. |
| Epitaxial latch-up immunity | Prevents destructive latch-up under overvoltage or ESD stress-ensures reliability in field-deployed test equipment and avionics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential analog multiplexing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG708BRUZ | Single 8:1, non-differential; 4.5 Ω RDS(on); 3 V to 5.5 V only; no ±20 V capability. | Only suitable for unipolar, low-voltage (<6 V) signal routing-not viable for ±15 V medical or industrial sensors. | Select only if operating exclusively from 3.3 V/5 V rails and differential signaling is not required. |
| MAX4617ESE+ | Dual 4:1 differential; 60 Ω RDS(on); −40 °C to +85 °C; same SO-28 package but different pinout (no A2, fewer channels). | Limited to 4 differential pairs; higher on-resistance increases gain error in precision gain blocks. | Use when channel count can be reduced and layout allows rework for non-pin-compatible pin mapping. |
Compared with ADG708BRUZ and MAX4617ESE+, the DG407BDJ-E3 uniquely delivers dual 8:1 differential switching with ±20 V tolerance, 45 Ω matching, and −86 dB isolation-making it irreplaceable for high-fidelity, bipolar, multi-channel instrumentation where signal integrity and voltage range are non-negotiable.

FAQ
What is the maximum supply voltage rating for DG407BDJ-E3?
The DG407BDJ-E3 has an absolute maximum V+ to V− rating of 44 V, allowing safe operation with ±20 V dual supplies or up to 40 V single supply. Operation beyond these limits risks permanent damage. The recommended operating range is ±5 V to ±20 V for optimal RDS(on) and leakage performance. DG407BDJ-E3 must never be subjected to transient overvoltages exceeding 44 V, even briefly.
Does DG407BDJ-E3 support single-supply operation?
Yes, DG407BDJ-E3 supports single-supply operation from 5 V to 40 V, with guaranteed analog signal range of 0 V to 12 V at V+ = 12 V. In single-supply mode, V− must be connected to GND, and the device maintains TTL-compatible logic thresholds. DG407BDJ-E3 retains its 45 Ω on-resistance and 115 ns transition time under these conditions, making it suitable for portable and industrial 12 V systems.
What is the function of the EN pin on DG407BDJ-E3?
The EN (enable) pin on DG407BDJ-E3 is an active-high TTL-compatible control that globally disables all internal switches when held low. When EN = 0 V, all S1a–S8a and S1b–S8b channels are open-circuited regardless of A0–A2 state-enabling safe stacking of multiple DG407BDJ-E3 devices on shared Da/Db lines. DG407BDJ-E3 requires no external pull-up on EN; it draws <1 μA in either state.
How does DG407BDJ-E3 achieve break-before-make switching?
DG407BDJ-E3 guarantees break-before-make behavior via internal timing control that enforces a minimum 10 ns (typical 39 ns) interval between turn-off of the previously selected channel and turn-on of the newly addressed channel. This is measured as tOPEN in the datasheet and prevents momentary shorting of differential inputs-a key requirement for protecting precision op-amps and ADC inputs. DG407BDJ-E3 achieves this without external timing components.
Is DG407BDJ-E3 RoHS-compliant and lead-free?
Yes, DG407BDJ-E3 is RoHS-compliant and lead-free, as indicated by the "-E3" suffix per Vishay's ordering nomenclature. It uses matte tin (Sn) terminations and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements. DG407BDJ-E3 is qualified to AEC-Q200 for stress testing and carries Vishay's standard 10-year product longevity commitment for industrial applications.
