Product details
Overview
DG306BDJ-E3 from Vishay Siliconix is a monolithic CMOS analog switch with four independent SPST channels, ±15 V analog signal range, 30 Ω typical RDS(on), 110 ns turn-on time, and break-before-make switching action-designed for programmable gain amplifiers and low-level switching in battery-powered instrumentation.
For engineers reviewing the DG306BDJ-E3 datasheet, DG306BDJ-E3 pinout, DG306BDJ-E3 application, or DG306BDJ-E3 equivalent, this device supports rail-to-rail analog signals up to ±15 V, operates from dual supplies (±15 V), delivers micropower consumption (30 nW), and guarantees latchup immunity via epitaxial layer construction.
Technical Context
The DG306BDJ-E3 implements four independent single-pole single-throw (SPST) switches in a 14-pin plastic DIP package, each bidirectional with symmetrical on-resistance and off-isolation. Its control logic accepts CMOS-compatible inputs (0 V ≤ VINL ≤ 3.5 V, 11 V ≤ VINH ≤ 15 V) and guarantees break-before-make timing only in DG307B-not applicable to DG306B.
Designed on Vishay's PLUS-40 CMOS process, it achieves low power dissipation and flat RDS(on) vs. analog voltage (±15 V full range), with charge injection of 30 pC and off-isolation of 62 dB at 500 kHz-enabling precision signal routing without signal degradation in low-frequency amplifier gain selection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full rail-to-rail signal handling across entire supply range |
| RDS(on) | 30 Ω typical - ensures minimal insertion loss and signal distortion in precision analog paths |
| tON | 110 ns - enables fast channel selection in multi-gain amplifier and data acquisition systems |
| Supply Current (I+, I−) | ±0.001 µA typical - sustains micropower operation critical for portable/battery-powered designs |
| Off-Isolation (OIRR) | 62 dB at 500 kHz - suppresses crosstalk between active and inactive channels in multiplexed circuits |
| Charge Injection | 30 pC - limits output voltage glitch during switching in high-impedance amplifier feedback networks |
| Input Logic Thresholds | VINL ≤ 3.5 V, VINH ≥ 11 V - ensures robust noise margin with standard CMOS drivers |
Pinout & Package
Package: 14-pin plastic DIP (dual in-line package), body width 7.62 mm (0.300"), lead pitch 2.54 mm (0.100"), RoHS-compliant (Pb-free terminations per -E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Switch Inputs (S1–S4) | Source terminals of four independent SPST switches; bidirectional conduction when enabled |
| 5, 6, 7, 10 | Switch Outputs (D1–D4) | Drain terminals; connect to load or signal path; block up to ±15 V when off |
| 8 | GND | Logic ground reference; must be tied to system ground for proper digital input operation |
| 9 | V− | Negative supply rail; sets lower analog voltage limit (e.g., −15 V); required for bipolar operation |
| 13, 14 | Control Inputs (IN1, IN2) | CMOS-compatible logic inputs controlling S1/D1 and S2/D2 pairs respectively |
| 11, 12 | No Connect (NC) | Internally unconnected pins; must remain floating or grounded per layout best practice |
| 14-Pin DIP Pin 1 | Index Mark | Notch or dot indicates Pin 1 location; used for orientation during PCB placement |

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 (12 V max), 60 Ω RDS(on), 150 ns tON, no negative rail support | Suitable for unipolar 0–12 V systems only; cannot replace DG306BDJ-E3 in ±15 V bipolar designs | Select only if operating exclusively with positive supplies and relaxed on-resistance requirements |
| ADG1404BRUZ | 4-channel SPST, ±15 V rated, 4.7 Ω RDS(on), but requires 3.3/5 V logic and costs ~3× more | Superior performance in precision instrumentation but incompatible with 11 V CMOS logic thresholds of legacy controllers | Choose when lowest on-resistance and highest speed are mandatory, and logic interface can be updated |
Compared with MAX4617CPD+ and ADG1404BRUZ, the DG306BDJ-E3 uniquely balances ±15 V rail-to-rail operation, 30 Ω RDS(on), and native 11 V CMOS logic compatibility-making it optimal for retrofitting legacy industrial and test equipment without redesigning control interfaces.

FAQ
What is the maximum analog signal voltage supported by DG306BDJ-E3?
The DG306BDJ-E3 supports analog signals from −15 V to +15 V when operated with ±15 V supplies. This full rail-to-rail range is specified in the Absolute Maximum Ratings table and confirmed in the Applications Hints section of the datasheet. Exceeding ±15 V risks permanent damage, and internal clamping diodes activate only for transient excursions beyond V+ or V− by ≤2 V.
Does DG306BDJ-E3 support single-supply operation?
Yes, DG306BDJ-E3 supports single-supply operation: connect V− to GND and apply V+ = 0–15 V. In this configuration, the analog signal range becomes 0 V to V+, and logic inputs retain CMOS compatibility (VINL ≤ 3.5 V, VINH ≥ 11 V). The datasheet explicitly states this capability in the DESCRIPTION section and Applications Hints table.
What is the function of pins 11 and 12 on DG306BDJ-E3?
Pins 11 and 12 are No Connect (NC) terminals per the Functional Block Diagram and Pin Configuration diagram in the DG304B/DG306B/DG307B datasheet. They are not bonded internally and must remain unconnected on the PCB. The datasheet warns against tying NC pins to any voltage or signal, as doing so may compromise device reliability or parametric performance.
How does DG306BDJ-E3 handle break-before-make timing?
DG306BDJ-E3 does not guarantee break-before-make timing-the datasheet explicitly restricts this feature to DG307B only. DG306BDJ-E3 implements four independent SPST switches with no inter-channel timing coordination. For break-before-make functionality, DG307BDJ-E3 (a 2-channel SPDT variant) must be selected instead, as confirmed in the Truth Table and Functional Block Diagram sections.
Is DG306BDJ-E3 RoHS compliant?
Yes, DG306BDJ-E3 is RoHS compliant. The "-E3" suffix denotes lead-free terminations per Directive 2011/65/EU, as stated in the Ordering Information table and confirmed in Vishay's Material Category Policy documentation. The device contains no intentionally added lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits.
