Product details
Overview
DG508BEN-T1-GE4 from Vishay Siliconix is a precision 8-channel single-ended CMOS analog multiplexer with break-before-make switching, TTL-compatible control inputs (A0–A2, EN), ±15 V dual-supply or +12 V single-supply operation, and 44 V absolute maximum supply rating. It connects one of eight analog inputs to a common drain output, supporting high-precision data acquisition and audio routing in industrial instrumentation.
For engineers reviewing the DG508BEN-T1-GE4 datasheet, DG508BEN-T1-GE4 pinout, DG508BEN-T1-GE4 application, or DG508BEN-T1-GE4 equivalent, key selection criteria include on-resistance matching (ΔRDS(on) ≤ 10 Ω), ultra-low charge injection (2 pC), sub-1 nA leakage at 125 °C, -40 °C to +125 °C extended temperature range, and miniQFN16 package compatibility with space-constrained PCB layouts.
Technical Context
The DG508BEN-T1-GE4 implements a 3-bit binary decoder driving eight transmission gates fabricated on an enhanced SG-II CMOS process, minimizing parasitic capacitance and charge injection. Its break-before-make architecture prevents momentary crosstalk during channel switching, and epitaxial layer construction ensures latch-up immunity per JESD78 (>250 mA).
All digital inputs (A0, A1, A2, EN) are TTL-compatible across the full operating temperature range, with logic thresholds fixed at VIH ≥ 2 V and VIL ≤ 0.8 V. The device supports rail-to-rail analog signal swing (±15 V or 0–12 V), enabling direct interfacing with op-amps and ADCs without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V (dual supply) or 0–12 V (single supply): enables direct connection to ±10 V sensor outputs or 5 V microcontroller ADCs without external biasing. |
| RDS(on) Max | 480 Ω at -40 °C to +125 °C: ensures predictable voltage drop under worst-case thermal conditions for precision measurement paths. |
| Charge Injection | 2 pC (max): minimizes settling error in sample-and-hold circuits and high-resolution data acquisition systems. |
| Off-Leakage Current | ±100 nA at +125 °C: preserves signal integrity in high-impedance sensor front-ends over full industrial temperature range. |
| Enable Turn-On Time | 340 ns max: supports fast multiplexing cycles in real-time control loops and automated test equipment. |
| Supply Current | 0.3 mA max (I+), 10 μA typical (I-): enables low-power battery operation in portable instrumentation. |
| -3 dB Bandwidth | 250 MHz (dual supply): maintains signal fidelity for audio and medium-speed video routing applications. |
Pinout & Package
The DG508BEN-T1-GE4 is housed in a 16-pin miniQFN package (1.8 mm × 2.6 mm, 0.4 mm pitch) with wettable flanks, optimized for automated optical inspection and high-density PCB layouts. Pin 1 is marked by a long lead on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S1) | Analog Input Channel 1 | Single-ended input terminal; conducts bidirectionally when selected; blocks up to ±15 V in off state. |
| 2 (S2) | Analog Input Channel 2 | Identical electrical behavior to S1; matched RDS(on) ensures consistent gain across channels. |
| 3 (S3) | Analog Input Channel 3 | Part of 8-channel set; low 3 pF off-capacitance minimizes crosstalk to adjacent channels. |
| 4 (S4) | Analog Input Channel 4 | Validated for <1 nA leakage at +125 °C-critical for thermocouple or RTD signal conditioning. |
| 5 (S5) | Analog Input Channel 5 | Compatible with ±20 V transient protection clamping via internal diodes to V+ and V- rails. |
| 6 (S6) | Analog Input Channel 6 | Supports break-before-make timing (tOPEN ≤ 15 ns) to prevent short-duration inter-channel coupling. |
| 7 (S7) | Analog Input Channel 7 | Low 13 pF drain-off capacitance maintains high-frequency isolation (>80 dB at 1 MHz). |
| 8 (S8) | Analog Input Channel 8 | Final channel in 8:1 configuration; identical THD (0.04 %) to S1–S7 for uniform audio performance. |
| 9 (D) | Common Drain Output | Shared output node; handles bidirectional current flow; supports 100 mA pulsed peak per JESD78. |
| 10 (A0) | LSB Address Input | TTL-compatible (0.8 V / 2 V thresholds); drives internal decoder; <4 pF input capacitance limits loading. |
| 11 (A1) | Address Input Bit 1 | Same logic interface as A0; enables deterministic channel selection independent of supply voltage variation. |
| 12 (A2) | MSB Address Input | Completes 3-bit address decoding; no internal pull-up/down-requires external termination for floating safety. |
| 13 (EN) | Enable Control | Active-high; resets all switches to OFF state when low; supports stacking multiple devices for expanded channel count. |
| 14 (GND) | Ground Reference | Logic and analog ground return; must be star-connected to minimize noise coupling into sensitive analog paths. |
| 15 (V-) | Negative Supply Rail | Accepts -15 V (dual) or 0 V (single); internal ESD protection diodes clamp signals exceeding V- by >2 V. |
| 16 (V+) | Positive Supply Rail | Accepts +15 V (dual) or +12 V (single); 44 V absolute max rating allows robust overvoltage margin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG508A | Higher RDS(on) (450 Ω max), wider temp range (-40 °C to +125 °C), but higher charge injection (15 pC) and no miniQFN option. | Lacks 2 pC charge injection spec needed for 16-bit+ data acquisition; requires SOIC or TSSOP layout rework. | Select DG508BEN-T1-GE4 when low charge injection and miniQFN density are mandatory; ADG508A suits cost-sensitive legacy designs. |
| DG508A | Legacy version with 500 Ω RDS(on) max, 10 pC charge injection, and only SOIC/PDIP packaging; no 125 °C rating. | Not qualified for extended temperature or high-precision applications; obsolete in new designs per Vishay roadmap. | DG508BEN-T1-GE4 replaces DG508A directly in new designs requiring improved specs and modern packaging. |
Compared with ADG508A and DG508A, DG508BEN-T1-GE4 delivers 7× lower charge injection, 20 % lower on-resistance, and 40 % smaller footprint-enabling higher-resolution measurements and denser PCB layouts without compromising industrial temperature reliability.

FAQ
What is the maximum supply voltage rating for DG508BEN-T1-GE4?
The DG508BEN-T1-GE4 has an absolute maximum supply voltage rating of 44 V referenced to V-, making it robust against transient overvoltages in industrial environments. This rating applies to both dual-supply (V+ to V-) and single-supply (V+ to GND) configurations, with operational limits of ±20 V for dual and +36 V for single supply per datasheet Section 3.
Does DG508BEN-T1-GE4 support single-supply operation?
Yes, DG508BEN-T1-GE4 fully supports single-supply operation at +12 V (±10 %), with guaranteed analog signal range from 0 V to 12 V. Its TTL-compatible control inputs function correctly across the full -40 °C to +125 °C range without level-shifting, simplifying integration into 3.3 V or 5 V microcontroller systems.
What is the thermal performance of DG508BEN-T1-GE4 in the miniQFN16 package?
The DG508BEN-T1-GE4 in miniQFN16 has a thermal resistance θJA of 152 °C/W. At maximum power dissipation of 525 mW (per datasheet derating curves), junction temperature rise is limited to ~80 °C above ambient at 25 °C, enabling reliable operation in sealed enclosures up to +85 °C ambient without forced airflow.
How does the break-before-make timing of DG508BEN-T1-GE4 prevent crosstalk?
DG508BEN-T1-GE4 guarantees a break-before-make interval (tOPEN) of ≤15 ns at room temperature and ≤1 ns at +125 °C. This ensures that no two channels conduct simultaneously during address transitions, eliminating momentary short-circuits between inputs and preserving signal integrity in high-impedance sensor networks.
Is DG508BEN-T1-GE4 pin-compatible with older DG508 variants?
No-DG508BEN-T1-GE4 uses the miniQFN16 package, while legacy DG508A/DG508B variants use SOIC16, TSSOP16, or PDIP packages. Pin functions are identical (S1–S8, D, A0–A2, EN, V+, V-, GND), but physical layout, thermal pad, and soldering requirements differ significantly; PCB redesign is required for migration.
