Product details
Overview
DG1408EEN-T1-GE4 from Vishay Siliconix is an 8-channel precision analog multiplexer IC with 3.2 Ω typical on-resistance, ±15 V dual-supply or +12 V single-supply operation, break-before-make switching, and rail-to-rail signal handling in a QFN16 (4 mm × 4 mm) package. It routes one of eight single-ended inputs to a common drain output under 3-bit binary address control (A0–A2), enabling high-fidelity signal routing in data acquisition and medical instrumentation.
For engineers reviewing the DG1408EEN-T1-GE4 datasheet, DG1408EEN-T1-GE4 pinout, DG1408EEN-T1-GE4 application, or DG1408EEN-T1-GE4 equivalent, key selection criteria include on-resistance flatness (0.5 Ω typ.), channel-to-channel matching (0.2 Ω typ.), low charge injection (100 pC typ. at ±15 V), and guaranteed operation from –40 °C to +125 °C in battery-powered and industrial systems.
Technical Context
The DG1408EEN-T1-GE4 uses a proprietary CMOS process to achieve ultra-low on-resistance variation over full analog voltage range (±15 V, 0 to +12 V, ±5 V), ensuring <0.02% THD across 20 Hz–20 kHz for audio and precision measurement signals. Its integrated decoder/driver eliminates need for external logic, and EN input enables global reset to all-switches-off state for cascaded configurations.
Break-before-make timing (50 ns typ. at ±15 V) prevents momentary crosstalk during channel transitions, while low parasitic capacitances-CS(off) = 14 pF, CD(on) = 123 pF-preserve bandwidth (46 MHz typ. at ±15 V) and minimize settling error in fast-switching applications like automated test equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RDS(on)) | 3.2 Ω typ. at ±15 V - ensures minimal insertion loss & voltage drop in precision signal paths |
| On-resistance flatness | 0.5 Ω typ. - maintains linearity across full ±15 V analog input range |
| Channel matching | 0.2 Ω typ. - enables accurate differential measurements and ratiometric sensing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1408BRUZ | Higher on-resistance (4.5 Ω max. vs. 4.7 Ω max.), lower bandwidth (34 MHz), same QFN16 package | Optimized for lower leakage (±0.1 pA typ.) but higher RDS(on) limits current drive capability | Select ADG1408BRUZ only if femtoamp-level leakage dominates design requirements over on-resistance |
| MAX4617ESE+ | SO-16 package, higher on-resistance (100 Ω typ.), no BBM, limited to +12 V single supply | Targeted at cost-sensitive, non-precision applications where size and speed are secondary | Choose MAX4617ESE+ only for legacy SOIC layouts or low-frequency (<100 kHz), low-accuracy signal routing |
Compared with ADG1408BRUZ and MAX4617ESE+, the DG1408EEN-T1-GE4 delivers superior combination of low on-resistance (3.2 Ω typ.), tight matching (0.2 Ω), and BBM timing-making it optimal for high-accuracy, multi-channel data acquisition where signal integrity and channel consistency are critical.

FAQ
What supply voltage ranges does the DG1408EEN-T1-GE4 support?
The DG1408EEN-T1-GE4 operates from dual supplies of ±4.5 V to ±16.5 V or a single supply of +4.5 V to +24 V. At ±15 V, it delivers 3.2 Ω typical on-resistance and 46 MHz bandwidth; at +12 V single supply, RDS(on) is 5.5 Ω typ. and bandwidth drops to 41 MHz. Full specifications are validated across –40 °C to +125 °C.
Does the DG1408EEN-T1-GE4 require a separate logic supply (VL)?
No, the DG1408EEN-T1-GE4 does not require a separate VL supply. Its digital inputs (A0–A2, EN) have fixed logic thresholds: VIL = 0.8 V max. and VIH = 2.0 V min., ensuring direct compatibility with 3.3 V and 5 V CMOS/TTL logic without level translation circuitry.
How does break-before-make (BBM) switching protect signal integrity in the DG1408EEN-T1-GE4?
The DG1408EEN-T1-GE4 guarantees a minimum 50 ns break interval (tOPEN) between deactivation of one channel and activation of the next. This prevents momentary shorting between adjacent analog sources-critical in multiplexed sensor arrays or relay-replacement applications where crosstalk could corrupt measurements or damage upstream circuitry.
What is the maximum continuous current rating for the DG1408EEN-T1-GE4?
The DG1408EEN-T1-GE4 supports up to 250 mA continuous switch current at TA = 25 °C in its QFN16 package. At +125 °C ambient, this derates to 100 mA. Exceeding these limits risks thermal runaway; layout must ensure adequate copper area under the exposed V− pad for heat dissipation.
Can the DG1408EEN-T1-GE4 be used in bidirectional signal paths?
Yes, the DG1408EEN-T1-GE4 is fully bidirectional: analog signals pass equally well from Sx to D or D to Sx. Its symmetrical CMOS structure ensures identical on-resistance, capacitance, and leakage characteristics regardless of signal direction-enabling flexible use in transceiver interfaces or shared bus architectures.
