Product details

Overview

DG408LEDY-T1-GE3 from Vishay Siliconix is an 8-channel single-ended analog multiplexer IC designed to route one of eight analog inputs to a common output under 3-bit binary address control (A0–A2). It operates on single supplies from 3 V to 16 V or dual supplies ±3 V to ±8 V, features 17 Ω typical on-resistance, 55 ns enable turn-on time, and break-before-make switching-ideal for precision data acquisition in portable medical instrumentation.

For engineers reviewing the DG408LEDY-T1-GE3 datasheet, DG408LEDY-T1-GE3 pinout, DG408LEDY-T1-GE3 application, or DG408LEDY-T1-GE3 equivalent, key selection criteria include guaranteed break-before-make timing, low 1 nA max off-leakage at -40 °C to +85 °C, RoHS-compliant SOIC-16 packaging, and compatibility with TTL/CMOS/LV logic interfaces across supply voltages.

Technical Context

The DG408LEDY-T1-GE3 integrates an internal voltage regulator to power its logic circuitry, reducing total device current to 6 μA max and enabling battery-operated system use. Its decoder/driver architecture supports simultaneous channel addressing and EN-controlled global disable, ensuring all switches are off during stacking configurations.

It implements true bidirectional analog conduction with rail-to-rail signal handling (0–12 V single-supply, ±5 V dual-supply), low parasitic capacitances (CS(OFF) = 5.5 pF, CD(ON) = 35 pF), and ESD protection rated at ±2.5 kV HBM-critical for test equipment and healthcare signal integrity.

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog multiplexer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX4617ESE+	8-channel, 35 Ω R_DS(on) typ., 100 ns t_ON, no internal regulator	Higher on-resistance limits resolution in 16-bit systems; requires external logic supply	Prefer DG408LEDY-T1-GE3 for low-power, high-accuracy portable designs where supply headroom is constrained
ADG408BRZ	8-channel, 45 Ω R_DS(on) typ., 120 ns t_ON, ±15 V dual-supply capable	Wider voltage range but slower switching and higher leakage (5 nA max)	Choose DG408LEDY-T1-GE3 for battery-powered applications needing <1 nA leakage and sub-100 ns timing

Compared with MAX4617ESE+ and ADG408BRZ, the DG408LEDY-T1-GE3 delivers superior combination of low on-resistance (17 Ω), ultra-low leakage (1 nA max), and integrated logic regulation-making it optimal for portable, precision, and low-power analog signal routing where supply efficiency and signal fidelity are critical.

FAQ

What supply voltage ranges does the DG408LEDY-T1-GE3 support?

The DG408LEDY-T1-GE3 supports single-supply operation from 3 V to 16 V and dual-supply operation from ±3 V to ±8 V. At V+ = 12 V and V− = 0 V, it delivers 17 Ω typical on-resistance and full rail analog signal range (0–12 V). The internal regulator ensures stable logic thresholds across this entire range, making DG408LEDY-T1-GE3 suitable for mixed-voltage system integration without external level-shifting circuitry.

Does the DG408LEDY-T1-GE3 require external decoupling capacitors?

Yes, the DG408LEDY-T1-GE3 requires local 0.1 μF ceramic decoupling capacitors placed as close as possible to pins 11 (V+) and 10 (V−), referenced to pin 9 (GND). This minimizes supply noise coupling into the analog path and stabilizes the internal logic regulator. Failure to implement proper decoupling may increase crosstalk and degrade off-isolation performance below the specified -99 dB at 100 kHz.

How does the break-before-make feature function in the DG408LEDY-T1-GE3?

The DG408LEDY-T1-GE3 guarantees break-before-make switching with t_OPEN ≥ 34 ns (typ.) at room temperature, preventing momentary shorting between adjacent channels during address transitions. This behavior is inherent to its decoder/driver design and does not require external timing control. In applications like sensor multiplexing, it eliminates transient injection that could corrupt ADC conversions-ensuring reliable operation in DG408LEDY-T1-GE3-based data acquisition systems.

Is the DG408LEDY-T1-GE3 pin-compatible with legacy DG408 variants?

Yes, the DG408LEDY-T1-GE3 is pin-for-pin compatible with the original DG408, DG409, and DG508/DG509 families in SOIC-16 packaging. All control (A0–A2, EN), power (V+, V−, GND), and signal (S1–S8, D) pin assignments match exactly. This allows drop-in replacement in existing designs while delivering improved specs: lower R_DS(on), reduced leakage, and enhanced ESD protection-without PCB layout changes.

What is the maximum analog signal frequency supported by the DG408LEDY-T1-GE3?

The DG408LEDY-T1-GE3 maintains -3 dB insertion loss up to 39 MHz at V+ = 5 V (single supply), with off-isolation remaining above -70 dB up to 1 MHz. For audio and sensor bandwidths (<200 kHz), its -99 dB off-isolation and -98 dB crosstalk ensure minimal inter-channel interference. System-level bandwidth is limited more by external source/load impedances and PCB parasitics than by the DG408LEDY-T1-GE3 itself.
