Product details
Overview
DG407BDN-T1-E3 from Vishay Siliconix is a dual 8-channel differential analog multiplexer IC designed to route one of eight differential input pairs to a common differential output in precision signal-path applications. It features 45 Ω on-resistance, 11 pC charge injection, ±20 V dual-supply operation (or 12 V single supply), break-before-make switching, and TTL-compatible control inputs. It is used in high-reliability data acquisition systems requiring low distortion and channel-to-channel isolation.
For engineers reviewing the DG407BDN-T1-E3 datasheet, DG407BDN-T1-E3 pinout, DG407BDN-T1-E3 application, or DG407BDN-T1-E3 equivalent, this page delivers verified specifications, PLCC-28 package details, functional truth table alignment, real-world use cases in medical instrumentation and ATE, and two validated alternative parts with documented technical and application differences.
Technical Context
The DG407BDN-T1-E3 implements a parallel-controlled, CMOS-based dual 8:1 differential multiplexer with fully independent Sa/Sb channel pairs per selected input-each pair routed simultaneously to Da/Db outputs. Its decoder/driver block supports 3-bit binary address (A0–A2) and active-low enable (EN), ensuring all switches are off when EN = 0.
Designed in a 44 V silicon-gate CMOS process, it achieves rail-to-rail analog signal handling (±15 V typical), latchup immunity via epitaxial layer, and guaranteed off-isolation of –86 dB at 1 MHz. Break-before-make timing (tOPEN ≤ 10 ns min., 39 ns typ.) prevents momentary shorting during channel transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Dual 8:1 differential multiplexer - selects one of eight matched differential input pairs to common Da/Db outputs. |
| On-resistance (RDS(on)) | 45 Ω typ. at ±15 V - ensures minimal signal attenuation and gain error in precision measurement paths. |
| Charge injection | 11 pC typ. - limits voltage glitch on high-impedance nodes (e.g., ADC sample capacitors) during switching. |
| Supply range | ±5 V to ±20 V dual or 5 V to 40 V single - supports industrial, medical, and avionics rails without level-shifting. |
| Off-isolation (OIRR) | –86 dB at 1 MHz - suppresses crosstalk between unselected differential channels in dense routing. |
| Transition time (tTRANS) | 115 ns typ. - enables sub-microsecond channel settling for >1 MSPS data acquisition systems. |
| Enable timing (tON(EN)) | 75 ns typ. - allows synchronized global reset across stacked multiplexers in modular test equipment. |
Pinout & Package
Package: 28-pin PLCC (Plastic Leaded Chip Carrier), body size 12.57 mm × 12.57 mm, lead pitch 1.27 mm, JEDEC MS-026 variant. RoHS-compliant, Pb-free, tape-and-reel packaging (-T1-E3 suffix).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | S1a–S8a (differential source a) | Positive-side terminals of eight differential input pairs; each connects to Da when selected. |
| 10, 11, 12, 13, 14, 15, 16, 17 | S1b–S8b (differential source b) | Negative-side terminals of same eight input pairs; each connects to Db when selected. |
| 9 | GND | Analog/digital reference ground - must be low-impedance and separated from noisy digital returns. |
| 18 | A0 | LSB address input - determines bit-0 selection within 3-bit binary address (A0–A2). |
| 19 | A1 | Mid-bit address input - part of decoding logic selecting one of eight differential channels. |
| 20 | A2 | MSB address input - completes 3-bit channel selection; no A3 (unlike DG406B). |
| 21 | EN | Active-low enable - forces all switches OFF when logic low; enables stacking multiple devices. |
| 22 | V− | Negative supply rail - supports bipolar operation down to –25 V (absolute max); referenced for all analog signals. |
| 23 | V+ | Positive supply rail - supports up to +44 V absolute max; defines upper analog signal limit. |
| 24, 25 | Da, Db | Differential output terminals - deliver selected Sxa/Sxb pair with matched delay and impedance. |
| 26, 27, 28 | NC | No-connect pins - electrically isolated; must remain unconnected per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed tOPEN ≥ 10 ns - eliminates transient shorts between differential sources during address changes. |
| Rail-to-rail analog range | Operates with inputs up to V+ and V− rails - preserves full dynamic range in ±15 V sensor interfaces. |
| TTL-compatible control inputs | Valid logic levels at VINH ≥ 2.4 V and VINL ≤ 0.8 V across –40 °C to +85 °C - simplifies interfacing with microcontrollers and FPGAs. |
| Low leakage (max ±5 nA) | Channel off-leakage ≤ ±20 nA over full temperature range - critical for high-impedance pH or thermocouple front-ends. |
| Epitaxial latchup immunity | Qualified per JEDEC JESD78 - ensures robustness against transient-induced latchup in harsh EMI environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG708BRUZ | Single 8:1 CMOS mux (not differential); 4.5 Ω RDS(on); 3 V to 5.5 V only; no ±20 V capability. | Only suitable for low-voltage, single-ended signal chains (e.g., IoT sensor nodes), not medical/ATE bipolar rails. | Select ADG708BRUZ only if operating strictly at 3.3 V/5 V and differential signaling is unnecessary. |
| MAX4617ESE+ | Dual 4:1 differential mux; 60 Ω RDS(on); –40 °C to +85 °C; compatible PLCC-16 package (smaller footprint). | Limited to four differential channels; lower channel count suits compact PCB layouts but requires two ICs for eight-channel coverage. | Choose MAX4617ESE+ when board space is constrained and eight-channel density is less critical than thermal footprint. |
Compared with DG407BDN-T1-E3, ADG708BRUZ offers lower on-resistance but lacks differential architecture and high-voltage support, while MAX4617ESE+ provides differential routing in half the channel count and smaller package-making DG407BDN-T1-E3 optimal for full eight-differential-channel, ±20 V systems where matching and isolation are paramount.

FAQ
What is the maximum analog signal voltage range supported by the DG407BDN-T1-E3?
The DG407BDN-T1-E3 supports analog signals from V− to V+, with absolute maximum ratings of –25 V to +44 V referenced to V−. In standard ±15 V dual-supply operation, its guaranteed analog signal range is –15 V to +15 V, enabling full-rail utilization in precision instrumentation front-ends without clamping or distortion.
Does the DG407BDN-T1-E3 require external pull-up resistors on its address or enable pins?
No, the DG407BDN-T1-E3 does not require external pull-up resistors. Its address (A0–A2) and enable (EN) inputs are TTL-compatible with guaranteed logic thresholds (VINH ≥ 2.4 V, VINL ≤ 0.8 V) and low input current (±1 μA), allowing direct connection to FPGA GPIOs or microcontroller outputs without additional biasing components.
How does the break-before-make interval prevent signal corruption in the DG407BDN-T1-E3?
The DG407BDN-T1-E3 guarantees a minimum break-before-make interval (tOPEN) of 10 ns, ensuring that the previously selected differential channel is fully disconnected before the next channel closes. This eliminates momentary shorting between differential source pairs-critical for preserving signal integrity in high-impedance, low-noise applications like ECG amplifiers or strain gauge bridges.
Can the DG407BDN-T1-E3 operate from a single 12 V supply?
Yes, the DG407BDN-T1-E3 supports single-supply operation from 5 V to 40 V. At V+ = 12 V and V− = 0 V, it delivers an analog signal range of 0 V to 12 V, RDS(on) ≤ 100 Ω, and transition time ≤ 163 ns-making it suitable for portable 12 V battery-powered instrumentation where dual supplies are impractical.
What is the meaning of "-T1-E3" in the DG407BDN-T1-E3 part number?
In DG407BDN-T1-E3, "-T1" denotes tape-and-reel packaging (standard for automated SMT assembly), and "-E3" indicates lead (Pb)-free termination and RoHS compliance per EU Directive 2011/65/EU. The base "DN" suffix specifies the 28-pin PLCC package, distinguishing it from the SOIC-wide-body variant (DG407BDW-T1-E3).
