Product details
Overview
DG405BDJ from Vishay Siliconix is a low-power, high-speed CMOS analog switch IC with four SPST switches arranged in two independent pairs, designed for bidirectional signal routing in precision analog systems. It features 23 Ω typical on-resistance, ±15 V analog signal range, 100 ns turn-on time, and operates from dual supplies up to ±22 V or single supply up to 44 V. It is used in stereo audio source selection, dual-slope integrators, and switched-capacitor filter circuits.
For engineers reviewing the DG405BDJ datasheet, DG405BDJ pinout, DG405BDJ application, or DG405BDJ equivalent, key selection criteria include guaranteed break-before-make timing (not applicable to DG405B), TTL/CMOS compatibility, low 40 pA channel-on leakage, flat on-resistance over full analog range, and 16-pin plastic DIP package suitability for through-hole prototyping and industrial control interfaces.
Technical Context
The DG405BDJ implements two independent SPST switch pairs-each pair controlled by one digital input (IN1, IN2)-with symmetrical conduction in both directions when on and blocking up to 30 V peak-to-peak when off. Its on-resistance remains flat across the full ±15 V analog range, enabling accurate signal switching without gain distortion.
It uses Vishay Siliconix's high-voltage silicon-gate process to achieve 44 V supply rating and low 60 pC charge injection. Unlike DG403B, DG405BDJ does not guarantee break-before-make action; its truth table shows simple ON/OFF per input, with no interlocked switching between pairs.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7, 9, 11, 13, 15 | No-connect (NC) | Internally unconnected; must be left floating or tied to GND per layout best practice |
| 2, 4, 6, 8 | Switch sources (S1–S4) | Analog inputs/outputs; bidirectional; each paired with corresponding drain |
| 10, 12 | Digital inputs (IN1, IN2) | TTL/CMOS-compatible control lines; logic high ≥2.4 V enables associated switch pair |
| 14, 16 | Switch drains (D1–D4) | Analog inputs/outputs; bidirectional; S1/D1 and S2/D2 form first SPST pair; S3/D3 and S4/D4 form second |
| 11 | GND | Ground reference for digital logic and substrate bias |
| 16 | V+ | Positive supply rail; supports up to +44 V (single) or +22 V (dual) |
| 8 | V− | Negative supply rail; supports down to −22 V in dual-supply operation |
Key Features

IC Role / Device Role / Timing Role: DG405BDJ serves as a low-distortion analog path selector-enabling sequential measurement of multiple sensors or references. Use Value: -81.7 dB off-isolation prevents signal bleed between test channels; 100 ns switching supports rapid test sequencing. | Use Scenario: Consolidating outputs from multiple 4–20 mA or thermocouple transmitters into a shared ADC front-end. IC Role / Device Role / Timing Role: DG405BDJ isolates individual sensor paths during sampling, preventing cross-talk and loading effects. Use Value: 23 Ω on-resistance introduces negligible series error in current-loop sensing; 44 V max supply supports industrial 24 V rail compatibility. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617CPD+ | Single-supply only (up to 36 V); 35 Ω RDS(on); 125 ns tON; SOIC-14 package | Lacks dual-supply support and ±15 V analog range; unsuitable for bipolar signal paths | Select when only unipolar signals and space-constrained PCBs are required |
| ADG1404BRUZ | 4-channel SPST; 4.7 Ω RDS(on); ±15 V range; 16-lead TSSOP; higher ICC (1.5 mA) | Lower on-resistance but higher supply current; smaller footprint; requires tighter layout for thermal management | Select for ultra-low distortion in high-precision instrumentation where power budget allows |
Compared with DG405BDJ, MAX4617CPD+ offers compact packaging but sacrifices bipolar operation and speed, while ADG1404BRUZ delivers superior on-resistance and matching at the cost of higher quiescent current and surface-mount assembly complexity.

FAQ
What is the maximum analog signal voltage supported by DG405BDJ?
DG405BDJ supports an analog signal range of ±15 V, meaning it can reliably pass or block signals spanning from -15 V to +15 V relative to ground. This is guaranteed across the full operating temperature range (-40 °C to +85 °C) and is enabled by its 44 V supply rating and internal clamping diodes. Signals exceeding V+ or V− are clamped, so proper supply rail sizing is essential to avoid distortion.
Does DG405BDJ provide break-before-make switching behavior?
No, DG405BDJ does not guarantee break-before-make switching. Unlike DG403B (which explicitly specifies tD = 5–12 ns break-before-make delay), DG405BDJ's truth table and functional description confirm independent ON/OFF control per input-meaning both switches in a pair may briefly overlap during transition. Designers requiring guaranteed isolation must add external timing control or select DG403B for interlocked operation.
What package type is DG405BDJ supplied in, and what are its mechanical dimensions?
DG405BDJ is supplied in a 16-pin plastic dual-in-line (DIP) package compliant with JEDEC MS-012. It measures 19.18 mm × 6.00 mm (0.755" × 0.236") with 2.54 mm (0.100") lead pitch and 0.300" body width. Pin 1 is marked with a notch or dot; the package is RoHS-compliant and features 100 % matte tin terminations (Pb-free "-E3" suffix variant also available).
Can DG405BDJ operate from a single supply, and what is the minimum required voltage?
Yes, DG405BDJ supports true single-supply operation from 5 V up to 44 V. The minimum functional supply is 5 V (V+ = 5 V, V− = GND), verified by logic threshold compatibility (VIN high ≥ 2.4 V, VIN low ≤ 0.8 V) and specified RDS(on) performance down to ±6 V dual supply (equivalent to 12 V single). At 5 V, on-resistance rises to ~55 Ω, but switching remains fully functional.
How does DG405BDJ differ from DG401BDJ and DG403BDJ in functionality?
DG405BDJ contains four SPST switches grouped as two independent pairs (S1/D1 + S2/D2; S3/D3 + S4/D4), each controlled by one digital input (IN1, IN2). DG401BDJ has two independent SPST switches (no pairing), while DG403BDJ offers four SPSTs in NO/NC configuration with break-before-make timing and interlocked truth table. DG405BDJ provides simpler, non-interlocked routing ideal for parallel channel selection-not sample-and-hold or precision timing where overlap must be avoided.
