Product details
Overview
DG506BEQ-T1-GE3 from Vishay Siliconix is a precision 16-channel single-ended CMOS analog multiplexer with break-before-make switching, 44 V absolute maximum supply rating, -40 °C to +125 °C operating range, and ultra-low 1 pC charge injection-designed for high-accuracy data acquisition in industrial instrumentation and ATE systems.
For engineers reviewing the DG506BEQ-T1-GE3 datasheet, DG506BEQ-T1-GE3 pinout, DG506BEQ-T1-GE3 application, or DG506BEQ-T1-GE3 equivalent, key selection criteria include on-resistance matching (≤10 Ω), off-isolation (-85 dB at 1 MHz), single/dual supply flexibility (±5 V to ±20 V or 12 V), and TSSOP28 package compatibility with high-density PCB layouts.
Technical Context
The DG506BEQ-T1-GE3 implements a 4-bit binary decoder driving 16 bidirectional analog switches, each featuring epitaxial-layer latch-up protection and TTL-compatible control inputs (A0–A3, EN). Its enhanced SG-II CMOS process minimizes parasitic capacitance (CD(off) = 31 pF, CS(off) = 3 pF) and leakage (<50 pA over full temperature range).
Break-before-make timing (tOPEN ≤ 30 ns at room temperature) prevents channel crosstalk during address transitions, while low RDS(on) matching (ΔRDS(on) ≤ 10 Ω) ensures consistent signal path impedance across all 16 channels under dual-supply (±15 V) or single-supply (12 V) operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Channels | 16 single-ended inputs to 1 common output - enables scalable sensor/mux front-end architectures |
| Supply Voltage Range | ±5 V to ±20 V dual or 12 V single supply - supports legacy ±15 V systems and modern low-voltage designs |
| On-Resistance (RDS(on)) | 170 Ω typ. at ±15 V - ensures minimal signal attenuation in precision measurement paths |
| Charge Injection (QINJ) | 1 pC max. - reduces settling error in sample-and-hold and ADC driver circuits |
| Off-Isolation (OIRR) | -85 dB at 1 MHz - suppresses adjacent-channel interference in multi-signal routing |
| Leakage Current | <50 pA at full temperature range - preserves accuracy in high-impedance sensor interfaces |
| Enable Turn-On Time | 151 ns typ. - supports sub-microsecond channel switching in real-time DAQ |
Pinout & Package
DG506BEQ-T1-GE3 is housed in a 28-pin TSSOP package (JEDEC MO-153, 9.7 mm × 4.4 mm × 1.2 mm), optimized for thermal performance (θJA = 97.9 °C/W) and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply rail | Bias source for analog switch conduction; supports up to +44 V absolute max |
| V- | Negative supply rail | Enables bipolar analog signal swing (e.g., ±15 V); clamps signals exceeding rails via internal diodes |
| GND | Ground reference | Logic and analog return path; decoupling required near pin for noise immunity |
| A0–A3 | Binary address inputs | Selects one of 16 channels (0–15); TTL-compatible with VIH ≥ 2.4 V, VIL ≤ 0.8 V |
| EN | Enable control | Active-high reset: forces all switches OFF when low; enables stacking of multiple devices |
| S1–S16 | Analog input terminals | 16 bidirectional analog inputs; conduct equally in both directions when selected |
| D | Common analog output | Single-ended output node shared by all 16 channels; connects to ADC or signal processor |
| NC | No-connect pins | Pins 4, 12, 25 - must remain unconnected per datasheet; no internal connection |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | tOPEN ≤ 30 ns prevents momentary shorting between adjacent channels during address changes |
| Ultra-low charge injection | 1 pC max. minimizes voltage glitch on sampling capacitors in precision ADC front-ends |
| Extended temperature range | -40 °C to +125 °C enables deployment in automotive engine control and industrial motor drives |
| Single/dual supply operation | Operates from 12 V single supply or ±15 V dual supply without external level-shifting circuitry |
| Latch-up immunity | Epitaxial layer design withstands >250 mA per JESD78 - eliminates risk in noisy power environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG506A | Higher typical RDS(on) (300 Ω vs. 170 Ω), wider ΔRDS(on) (25 Ω vs. 10 Ω), lower OIRR (-75 dB) | Limited to commercial temperature range (-40 °C to +85 °C); not qualified for extended industrial use | Choose DG506BEQ-T1-GE3 for higher accuracy, wider temp range, and better isolation in mission-critical systems |
| DG506A | Legacy version with higher QINJ (3 pC vs. 1 pC), higher leakage (>100 pA), no 44 V rating | Not rated for 125 °C operation; lacks enhanced SG-II process benefits | DG506BEQ-T1-GE3 provides measurable improvements in charge injection, leakage, and ruggedness |
Compared with ADG506A and DG506A, DG506BEQ-T1-GE3 delivers tighter RDS(on) matching, lower charge injection, and extended temperature capability-enabling higher-accuracy, longer-lifetime designs in harsh environments without layout or supply changes.

FAQ
What is the maximum analog signal voltage range supported by DG506BEQ-T1-GE3?
DG506BEQ-T1-GE3 supports full-rail analog signal swing: from V− to V+ across its 16 channels. With ±15 V supplies, it handles ±15 V signals; with 12 V single supply, it operates from 0 V to 12 V. Absolute maximum ratings extend to ±44 V on V+ and V−, but analog signals must stay within the supply rails to avoid clamping.
Does DG506BEQ-T1-GE3 require external pull-up or pull-down resistors on address lines A0–A3?
No, DG506BEQ-T1-GE3 does not require external biasing on A0–A3. Its TTL-compatible inputs have defined thresholds (VIH ≥ 2.4 V, VIL ≤ 0.8 V) and low input current (±1 µA), allowing direct connection to microcontroller GPIOs or FPGA outputs without additional resistors.
Can DG506BEQ-T1-GE3 be used in single-supply 5 V systems?
While DG506BEQ-T1-GE3 is characterized down to ±5 V dual supply, its minimum recommended dual supply is ±5 V and single-supply operation starts at 12 V. For true 5 V single-supply use, consider alternatives-DG506BEQ-T1-GE3's RDS(on) and leakage are not specified below 12 V operation.
How does the break-before-make interval affect timing in high-speed multiplexing?
The break-before-make interval (tOPEN ≤ 30 ns at room temperature) guarantees no overlap between channel conduction states during address transitions. This eliminates transient shorts that cause crosstalk or signal corruption-critical when switching between high-impedance sources like piezoelectric sensors or photodiode amplifiers in DG506BEQ-T1-GE3-based systems.
Is DG506BEQ-T1-GE3 RoHS compliant and halogen-free?
Yes, DG506BEQ-T1-GE3 is RoHS-compliant and halogen-free per Vishay's material categorization standard (document 99912). The "-GE3" suffix explicitly denotes green, lead-free, and halogen-free packaging meeting JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements.
