Product details
Overview
DG306BDJ from Vishay Siliconix is a monolithic CMOS analog switch with four independent SPST switches, ±15 V analog signal range, 30 Ω typical RDS(on), and 110 ns turn-on time. It operates from dual supplies (±15 V), supports rail-to-rail analog signals, and is designed for low-power instrumentation and programmable gain amplifier circuits.
For engineers reviewing the DG306BDJ datasheet, DG306BDJ pinout, DG306BDJ application, or DG306BDJ equivalent, this device offers verified break-before-make timing, guaranteed latchup immunity, micropower operation (30 nW), and compatibility with CMOS logic levels - critical for battery-powered precision switching systems.
Technical Context
The DG306BDJ implements four independent single-pole single-throw (SPST) analog switches on a single die using Vishay's PLUS-40 CMOS process. Each switch conducts bidirectionally with matched on-resistance flatness across the full ±15 V analog range and exhibits guaranteed break-before-make behavior only in DG307B - not applicable to DG306BDJ.
It features CMOS-compatible digital inputs (logic "0" ≤ 3.5 V, logic "1" ≥ 11 V), internal epitaxial layer latchup protection, and operates with V− tied to −15 V and GND at 0 V. Supply current remains below 100 µA over −40 °C to +85 °C, enabling use in portable systems without thermal derating concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full rail-to-rail signal handling with no clipping in ±15 V supply systems |
| RDS(on) | 30 Ω typical - ensures minimal insertion loss and voltage drop in signal paths up to ±10 V |
| tON | 110 ns - enables fast channel selection in multiplexed data acquisition and real-time control loops |
| Supply Current (I+, I−) | ±0.001 µA to ±100 µA - ultra-low quiescent power supports multi-year battery life in portable instruments |
| Off-Leakage (IS(off), ID(off)) | ±0.1 nA max - preserves signal integrity in high-impedance sensor interfaces and precision integrators |
| Charge Injection | 30 pC - limits voltage glitch in sample-and-hold and switched-capacitor circuits |
| Off-Isolation (OIRR) | 62 dB at 500 kHz - suppresses crosstalk between adjacent channels in multi-channel signal routing |
Pinout & Package
DG306BDJ is housed in a 14-pin plastic DIP package (JEDEC MS-001AC) with 0.300″ wide body, 2.54 mm lead pitch, and 19.30 mm × 8.26 mm footprint. Pin 1 is top-left corner when notch faces up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7 | Switch Terminals (S1–S4, D1–D4) | Four independent SPST switch pairs: S1/D1, S2/D2, S3/D3, S4/D4 - bidirectional conduction when enabled |
| 8 | GND | Logic and analog reference ground - must be connected to system 0 V for proper CMOS input threshold and leakage control |
| 9, 10, 11, 12 | Control Inputs (IN1–IN4) | CMOS-compatible digital inputs: logic high ≥11 V enables corresponding switch; logic low ≤3.5 V disables it |
| 13 | V− | Negative supply rail - must be connected to −15 V (or other negative rail) to enable full ±15 V analog range |
| 14 | V+ | Positive supply rail - must be connected to +15 V (or other positive rail) to bias internal circuitry and define analog upper limit |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make guarantee | Not implemented - DG306BDJ has independent SPST switches; only DG307B provides SPDT break-before-make |
| Latchup immunity | Guaranteed via epitaxial layer - eliminates risk of destructive latchup under transient overvoltage or ESD stress |
| Micropower operation | 30 nW typical - enables integration into always-on sensor nodes without measurable battery drain |
| Rail-to-rail analog range | ±15 V with ±15 V supplies - allows direct interfacing with op-amps, DACs, and ADCs operating at full supply rails |
| Flat RDS(on) vs. voltage | ≤25 Ω variation over ±10 V range - maintains consistent gain and linearity in precision analog signal routing |
Applications
| Programmable Gain Amplifier | Low-Level Multiplexer |
|---|---|
Use Scenario: Digitally selecting feedback resistor values in an op-amp circuit to achieve discrete gain steps (1×, 10×, 100×, 1000×). IC Role / Device Role / Timing Role: DG306BDJ acts as low-leakage, low-RDS(on) analog switch array routing resistors into feedback path - no active amplification. Use Value: 30 nW power draw and ±0.1 nA off-leakage prevent gain error drift and offset accumulation in high-Z feedback networks. |
Use Scenario: Routing multiple low-amplitude sensor outputs (thermocouples, strain gauges) to a shared ADC input. IC Role / Device Role / Timing Role: DG306BDJ serves as bidirectional analog multiplexer - each SPST switch isolates one sensor channel during sampling. Use Value: 62 dB off-isolation and 30 pC charge injection minimize crosstalk and sampling glitches in 16-bit+ data acquisition. |
| Battery-Powered Instrumentation | Process Control Signal Routing |
Use Scenario: Portable multimeter or handheld oscilloscope front-end switching between AC/DC coupling, attenuation, and input ranges. IC Role / Device Role / Timing Role: DG306BDJ functions as rail-to-rail analog path selector - handles ±15 V input signals while consuming sub-µA supply current. Use Value: 110 ns tON enables rapid range changes; 30 Ω RDS(on) avoids loading high-impedance probe circuits. |
Use Scenario: Isolating and routing 4–20 mA loop signals or ±10 V analog control outputs in PLC I/O modules. IC Role / Device Role / Timing Role: DG306BDJ provides galvanically isolated signal path selection - used with external protection diodes and current-limiting resistors. Use Value: ±15 V rating accommodates industrial signal swings; latchup immunity ensures reliability in electrically noisy factory environments. |
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 +12 V); 60 Ω RDS(on); 100 ns tON; no negative rail support | Not suitable for ±15 V bipolar signal routing; requires level-shifting for dual-supply systems | Select when cost-sensitive single-supply designs dominate and rail-to-rail bipolar operation is unnecessary |
| ADG1404BRUZ | 4-channel SPST; ±15 V rating; 4.7 Ω RDS(on); 105 ns tON; higher supply current (200 µA) | Superior on-resistance and bandwidth but consumes >200× more quiescent power than DG306BDJ | Select when lowest possible signal distortion is required and micropower operation is secondary |
Compared with MAX4617CPD+ and ADG1404BRUZ, DG306BDJ uniquely balances ultra-low power (30 nW), ±15 V capability, and 30 Ω on-resistance - making it optimal for portable instrumentation where battery life and bipolar signal fidelity are both critical.

FAQ
What is the maximum analog signal voltage supported by DG306BDJ?
DG306BDJ supports a full ±15 V analog signal range when operated with V+ = +15 V and V− = −15 V. Signals exceeding these rails are clamped by internal diodes, so input voltages must remain within (V− − 2 V) to (V+ + 2 V) to avoid forward conduction and potential damage. The absolute maximum analog voltage is ±15 V under normal operation.
Does DG306BDJ support single-supply operation?
Yes, DG306BDJ supports single-supply operation: connect V− to 0 V and apply V+ = +15 V to enable 0 V to +15 V analog signal handling. Logic thresholds remain unchanged (IN ≤ 3.5 V = OFF, IN ≥ 11 V = ON), and RDS(on) increases slightly versus dual-supply mode - see Figure 4 in datasheet Document Number 71403.
What is the guaranteed break-before-make behavior of DG306BDJ?
DG306BDJ does not implement break-before-make switching - it contains four independent SPST switches with no inter-channel timing coordination. Break-before-make is only guaranteed in DG307BDJ (SPDT configuration). For DG306BDJ, simultaneous ON/OFF transitions across channels are possible and must be managed externally via control sequencing.
How does DG306BDJ prevent latchup in harsh environments?
DG306BDJ incorporates an epitaxial layer structure that guarantees latchup immunity per JEDEC JESD78. This design prevents parasitic SCR activation even under transient overvoltage, ESD events, or supply sequencing faults - a key reliability feature validated across −40 °C to +85 °C operation.
Can DG306BDJ be used with CMOS microcontroller GPIOs directly?
Yes - DG306BDJ accepts standard CMOS logic levels: logic "0" ≤ 3.5 V and logic "1" ≥ 11 V. Most 5 V or 15 V CMOS microcontrollers meet this, but 3.3 V GPIOs require level translation (e.g., TC7WU04) since 3.3 V < 11 V threshold. Always verify actual output high voltage under load per MCU datasheet before direct connection.
