Product details
Overview
DG408LEDY-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 (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 medical instrumentation and portable test equipment.
For engineers reviewing the DG408LEDY-GE3 datasheet, DG408LEDY-GE3 pinout, DG408LEDY-GE3 application, or DG408LEDY-GE3 equivalent, key selection criteria include its 1 nA max. off-leakage, -99 dB off-isolation at 100 kHz, TTL/CMOS/LV logic compatibility, low 6 μA max. supply current, and SOIC16 package suitability for space-constrained industrial signal routing designs.
Technical Context
The DG408LEDY-GE3 integrates an internal voltage regulator to power its logic circuitry, reducing overall device power consumption and enabling robust operation in battery-powered systems. Its decoder/driver architecture ensures precise channel selection with guaranteed break-before-make timing to prevent crosstalk during switching transitions.
Designed for wide-voltage flexibility, it supports analog signal ranges from 0 V to V+ (single supply) or ±V (dual supply), with rail-to-rail blocking capability in the off state and bidirectional conduction when on-making it suitable for both unipolar and bipolar signal conditioning paths in mixed-signal front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RDS(on)) | 17 Ω typ. at V+ = 12 V - enables low insertion loss and minimal signal distortion in precision analog paths |
| Enable turn-on time (tON(EN)) | 55 ns typ. - supports high-speed multiplexing in real-time data acquisition systems |
| Off-leakage current (IS(OFF)) | 1 nA max. - preserves accuracy in high-impedance sensor interfaces and low-current measurement circuits |
| Off-isolation | -99 dB at 100 kHz - suppresses inter-channel interference in multi-sensor monitoring applications |
| Supply current (I+) | 6 μA max. at V+ = 5 V - extends battery life in portable healthcare and field instrumentation |
| Analog signal range | 0 V to 12 V (single supply) - accommodates full-scale industrial sensor outputs without level-shifting |
| Logic compatibility | TTL/CMOS/LV (3 V) - simplifies interface with microcontrollers, FPGAs, and legacy digital controllers |
Pinout & Package
Package: 16-pin narrow SOIC (SO-16), 6.0 mm × 10.0 mm body, 1.27 mm pitch, RoHS-compliant lead-free finish (-GE3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable input | Active-high logic control to globally disable all switches; resets multiplexer to all-off state for cascading |
| 2 (A0), 3 (A1), 4 (A2) | Binary address inputs | 3-bit code selects one of eight analog channels (S1–S8); TTL/CMOS compatible over full temperature range |
| 5–12 (S1–S8) | Analog switch inputs | Eight single-ended source terminals; each conducts bidirectionally with rail-to-rail blocking when off |
| 13 (D) | Common analog output | Shared drain node for all channels; low capacitance (35 pF on, 5.5 pF off) minimizes loading on downstream stages |
| 14 (V−) | Negative supply | Accepts ground (0 V) or negative rail (down to −8 V); defines lower analog signal boundary |
| 15 (GND) | Ground reference | Digital and analog ground return; must be low-impedance for stable logic and analog performance |
| 16 (V+) | Positive supply | Supports 3 V to 16 V; powers analog switches and internal regulator for logic circuitry |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4051ACPE+ | Higher 100 Ω RDS(on), wider 2.7–15 V supply, no internal regulator | Lower precision; suited for non-critical general-purpose switching where leakage & flatness less critical | Select when cost sensitivity outweighs on-resistance and leakage requirements |

FAQ
What is the maximum analog signal voltage range supported by the DG408LEDY-GE3?
The DG408LEDY-GE3 supports analog signals from 0 V to V+ in single-supply mode (e.g., 0–12 V at V+ = 12 V) or from V− to V+ in dual-supply mode (e.g., −5 V to +5 V at ±5 V). It blocks voltages up to the supply rails in the off state and conducts bidirectionally when on-enabling true rail-to-rail analog signal handling without clamping diodes or external protection.
Does the DG408LEDY-GE3 require an external logic supply voltage?
No, the DG408LEDY-GE3 does not require an external logic supply. It integrates an internal voltage regulator that powers its digital control circuitry from the main V+ supply. This allows direct interfacing with TTL, CMOS, and LV logic levels using only the primary analog supply-reducing system complexity and component count in battery-operated and space-constrained designs.
How does the break-before-make feature function in the DG408LEDY-GE3?
The DG408LEDY-GE3 guarantees break-before-make switching via internal timing control: the previously selected channel is fully disconnected before the newly addressed channel connects. This prevents momentary shorting between input channels during address transitions-critical for protecting sensitive sensors and avoiding transient errors in precision measurement systems. The specification is verified across temperature and supply conditions.
Can the DG408LEDY-GE3 operate with a 3 V single supply?
Yes, the DG408LEDY-GE3 is fully specified for 3 V single-supply operation. At V+ = 3 V, it delivers 63 Ω typical on-resistance, 211 ns transition time, and maintains 1 nA max. off-leakage. Logic inputs accept 0.4 V (low) and 2 V (high) thresholds, ensuring reliable interface with 3 V microcontrollers and low-voltage FPGAs-making it suitable for modern ultra-low-power portable instrumentation.
What is the thermal derating behavior of the DG408LEDY-GE3 in SOIC16 package?
In its 16-pin narrow SOIC package, the DG408LEDY-GE3 has a power dissipation limit of 600 mW at ≤75 °C ambient. Above 75 °C, thermal derating is 8 mW/°C-meaning maximum allowable power drops linearly to zero at approximately 150 °C junction temperature. This derating curve ensures safe operation in enclosed industrial enclosures and automotive under-hood environments when proper PCB copper area and airflow are applied.
