Product details
Overview
DG408LEDQ-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 ±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 instruments.
For engineers reviewing the DG408LEDQ-GE3 datasheet, DG408LEDQ-GE3 pinout, DG408LEDQ-GE3 application, or DG408LEDQ-GE3 equivalent, key selection criteria include its 17 Ω RDS(on) at 12 V, -99 dB off-isolation at 100 kHz, TTL/CMOS/LV logic compatibility, QFN16 (3 mm × 3 mm) RoHS-compliant package, and guaranteed break-before-make timing.
Technical Context
The DG408LEDQ-GE3 integrates an internal voltage regulator to power logic circuitry independently, reducing total supply current to ≤6 μA and enabling battery-operated system use. Its decoder/driver architecture supports simultaneous address decoding and enable-controlled channel reset across all eight switches.
Break-before-make timing is guaranteed per channel transition, preventing momentary crosstalk during switching. All digital inputs (A0–A2, EN) are TTL-compatible over the full -40 °C to +85 °C industrial temperature range, with input thresholds scaling with V+ supply voltage.
Key Specifications

FAQ
What supply voltage ranges does the DG408LEDQ-GE3 support?
The DG408LEDQ-GE3 supports single-supply operation from 3 V to 16 V and dual-supply operation from ±3 V to ±8 V. At 12 V single supply, it achieves 17 Ω typical RDS(on); at ±5 V dual supply, RDS(on) drops to 15 Ω. The device maintains full functionality-including TTL-compatible logic inputs and break-before-make timing-across this entire range.
Does DG408LEDQ-GE3 require external decoupling capacitors?
Yes, DG408LEDQ-GE3 requires local 0.1 μF ceramic decoupling capacitors placed as close as possible to pins 14 (V-) and 16 (V+), referenced to pin 15 (GND). This is essential to suppress switching transients and ensure stable operation, especially during fast enable transitions (tON(EN) = 55 ns) and high-frequency analog signal routing.
How does the internal voltage regulator in DG408LEDQ-GE3 benefit system design?
The internal voltage regulator in DG408LEDQ-GE3 powers the logic section independently, limiting total supply current to ≤6 μA even when all control inputs are active. This eliminates the need for separate logic supply rails and significantly reduces power consumption in battery-operated devices such as portable medical monitors and handheld test equipment using DG408LEDQ-GE3.
Can DG408LEDQ-GE3 be used with 3 V logic microcontrollers?
Yes, DG408LEDQ-GE3 supports 3 V logic levels: VINL ≤ 0.4 V and VINH ≥ 2.0 V at V+ = 3 V, ensuring reliable interface with 3 V MCUs and FPGAs. Its inputs are fully TTL/CMOS/LV compatible across the full -40 °C to +85 °C temperature range, with no level-shifting circuitry required when driving A0–A2 and EN from 3 V digital sources.
What is the maximum analog signal voltage that can be routed through DG408LEDQ-GE3?
The maximum analog signal voltage for DG408LEDQ-GE3 equals the supply rails: 0 V to V+ in single-supply mode (e.g., 0–12 V), or V- to V+ in dual-supply mode (e.g., -5 V to +5 V). Signals exceeding these limits are clamped by internal diodes; forward diode current must be limited to ≤30 mA per terminal to avoid damage, as specified in the absolute maximum ratings.
