Product details
Overview
DG408DJ-E3 from Vishay Siliconix is an 8-channel single-ended CMOS analog multiplexer with TTL-compatible control logic, 100 Ω on-resistance, 160 ns transition time, and ±5 V to ±20 V dual-supply or +5 V to +36 V single-supply operation. It routes one of eight analog inputs to a common output in data acquisition, audio switching, and ATE systems.
For engineers reviewing the DG408DJ-E3 datasheet, DG408DJ-E3 pinout, DG408DJ-E3 application, or DG408DJ-E3 equivalent, key selection criteria include break-before-make switching, low 20 pC charge injection, 0.5 nA max off-leakage at full temperature range, and 16-pin plastic DIP package compatibility with legacy through-hole layouts.
Technical Context
The DG408DJ-E3 implements a silicon-gate CMOS architecture with epitaxial latchup protection and 44 V absolute maximum supply rating. Its 3-bit binary address decoder (A0–A2) selects one of eight bidirectional analog channels, while the EN input forces all switches into high-impedance off-state for cascading.
Break-before-make timing ensures no momentary crosstalk between adjacent channels during switching. All digital inputs meet TTL voltage thresholds (VIH ≥ 2.4 V, VIL ≤ 0.8 V) across –40 °C to +85 °C, and internal clamping diodes protect against analog signals exceeding V+ or V– rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 100 Ω max - ensures minimal signal attenuation and gain error in precision analog paths |
| Transition time | 160 ns typ - supports sampling rates up to ~3 MHz in multiplexed ADC front-ends |
| Charge injection | 20 pC typ - limits voltage glitch on sampled-hold capacitors, critical for 12-bit+ resolution |
| Off-leakage current | ±5 nA max at full temp - preserves accuracy in high-impedance sensor interfaces and battery-powered meters |
| Supply range | +5 V to +36 V single or ±5 V to ±20 V dual - enables use in industrial PLCs, medical monitors, and avionics with wide rail flexibility |
| Enable turn-off time | 105–150 ns - allows synchronized shutdown across stacked multiplexers without signal contention |
| Off isolation | –75 dB min at 1 MHz - suppresses crosstalk between inactive channels in multi-signal routing |
Pinout & Package
Package: 16-pin plastic DIP (JEDEC MS-012), 0.300" wide body, through-hole mountable. Pin pitch: 0.100", row spacing: 0.300". RoHS-compliant lead (Pb)-free finish per -E3 suffix.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S1) | Analog input channel 1 | Bidirectional path; conducts equally in both directions when selected |
| 2 (S2) | Analog input channel 2 | Same electrical behavior as S1; matched RDS(on) within 15 Ω across all channels |
| 3 (S3) | Analog input channel 3 | Internally clamped to V+ and V– rails; withstands overvoltage up to ±44 V differential |
| 4 (S4) | Analog input channel 4 | Low 3 pF off-capacitance minimizes feedthrough at RF frequencies |
| 5 (S5) | Analog input channel 5 | Compatible with single-supply operation (V– = GND); no level-shifting required |
| 6 (S6) | Analog input channel 6 | Supports rail-to-rail analog signal range up to ±15 V with 15 V supplies |
| 7 (S7) | Analog input channel 7 | Matched timing characteristics ensure consistent settling across all 8 channels |
| 8 (S8) | Analog input channel 8 | Worst-case off-isolation occurs here due to proximity to drain pin; still ≥ –75 dB |
| 9 (D) | Common analog output | Shared output node; connects to ADC input, op-amp summing junction, or instrumentation amp |
| 10 (EN) | Enable control input | Active-high; drives all switches open when low - essential for power sequencing and fault isolation |
| 11 (A0) | LSB address bit | TTL-compatible; VIH ≥ 2.4 V, VIL ≤ 0.8 V across full temperature range |
| 12 (A1) | Address bit 1 | Directly interfaces microcontroller GPIO without level translation |
| 13 (A2) | MSB address bit | Together with A0/A1, selects one of eight channels via standard binary decoding |
| 14 (V–) | Negative supply rail | Accepts –25 V to GND; must be connected even in single-supply mode (V– = GND) |
| 15 (GND) | Signal ground reference | Separate from power ground in mixed-signal designs; decoupling recommended near pin |
| 16 (V+) | Positive supply rail | Accepts GND to +44 V; 44 V abs max rating enables robustness in transient-prone environments |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 10 ns minimum tOPEN prevents signal shorting during channel transitions |
| Single-supply capability | Operates from +5 V to +36 V with V– tied to GND - eliminates need for negative rail in portable instruments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4051ACPP+ | 8-channel, 100 Ω RDS(on), but only ±5 V dual or +5 V single supply; no 44 V rating | Limited to low-voltage embedded systems; unsuitable for industrial ±15 V signal chains | Select when board space is constrained (16-pin PDIP same footprint) and supply rails are strictly ≤ ±5 V |
| ADG1408BRUZ | 8-channel, 4.7 Ω RDS(on), but requires ±15 V or +12 V single supply; higher 30 pC charge injection | Better for low-distortion audio; worse for precision DC-coupled measurements due to higher Q | Select when ultra-low on-resistance is critical and system can accommodate tighter supply constraints |
Compared with MAX4051ACPP+ and ADG1408BRUZ, the DG408DJ-E3 offers widest supply flexibility (±20 V / +36 V), highest ruggedness (44 V abs max), and optimal balance of on-resistance, charge injection, and leakage for general-purpose industrial and medical multiplexing.

FAQ
What is the maximum supply voltage rating for DG408DJ-E3?
The DG408DJ-E3 has an absolute maximum supply voltage rating of 44 V between V+ and V– pins. This allows operation with ±20 V dual supplies or +36 V single supply while surviving transient overvoltages common in industrial settings. Exceeding 44 V risks permanent damage, and operation above this limit is not guaranteed or tested.
Does DG408DJ-E3 support single-supply operation?
Yes, DG408DJ-E3 supports true single-supply operation from +5 V to +36 V with V– connected to GND. The device maintains full functionality including TTL-compatible logic inputs, 100 Ω on-resistance, and 20 pC charge injection. No level-shifting circuitry is needed, simplifying design in battery-powered or cost-sensitive applications.
What is the purpose of the EN (enable) pin on DG408DJ-E3?
EN is an active-high enable input that forces all eight analog switches into the off state when driven low. This feature enables safe stacking of multiple DG408DJ-E3 devices on a shared output bus, prevents signal contention during power-up/down, and supports system-level fault isolation. When EN = 0 V, no channel conducts regardless of address inputs.
How does DG408DJ-E3 achieve latchup immunity?
DG408DJ-E3 uses a silicon-gate CMOS process with an epitaxial layer to prevent latchup under overvoltage or overcurrent conditions. This structural design eliminates parasitic SCR formation, allowing the device to withstand transient faults without destructive failure - a critical reliability feature for unattended industrial and medical equipment where field returns must be minimized.
Is DG408DJ-E3 RoHS-compliant?
Yes, DG408DJ-E3 is RoHS-compliant and Pb-free, as indicated by the "-E3" suffix in its ordering part number. It meets EU Directive 2011/65/EU requirements and is suitable for environmentally regulated markets. Full compliance documentation, including material declarations and test reports, is available from Vishay upon request.
