Product details
Overview
DG1412EEN-T1-GE4 from Vishay Siliconix is a quad SPST analog switch with normally open (NO) configuration, designed for precision signal routing in ±15 V, ±5 V, and +12 V dual/single-supply systems. It delivers 1.5 Ω typical on-resistance, 70 ns turn-on time, and rail-to-rail analog signal handling up to ±15 V - enabling high-fidelity switching in medical instrumentation and automated test equipment.
For engineers reviewing the DG1412EEN-T1-GE4 datasheet, DG1412EEN-T1-GE4 pinout, DG1412EEN-T1-GE4 application, or DG1412EEN-T1-GE4 equivalent, this page provides verified electrical specs, package mapping to QFN-16 (4 mm × 4 mm), truth table behavior (logic "1" = switch ON), thermal derating data, and real-world application context for signal integrity-critical designs.
Technical Context
The DG1412EEN-T1-GE4 implements CMOS-based transmission gate architecture with integrated level-shifting logic, supporting TTL/CMOS-compatible 0.8 V / 2 V thresholds without requiring a separate VL supply. Its bi-directional switches operate across full supply rails (V− to V+), with guaranteed break-before-make timing only in DG1413E - not applicable here.
It features low parasitic capacitance (CD(ON) = 87 pF, CS(OFF) = 24 pF), minimal charge injection (−41 pC at ±15 V), and flat on-resistance (0.2 Ω variation over signal range), ensuring low THD (0.0039 %) and high off-isolation (−78 dB) in audio, data acquisition, and relay-replacement circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 1.5 Ω typical at ±15 V - ensures <0.1 % insertion loss in 50 Ω systems |
| Supply range | ±4.5 V to ±16.5 V dual or +4.5 V to +24 V single - supports industrial and medical power architectures |
| Switching speed | 70 ns tON / 50 ns tOFF at ±15 V - enables >1 MHz multiplexed signal sampling |
| Analog bandwidth | 150 MHz (−3 dB) - preserves integrity of fast pulses and video signals |
| Logic compatibility | 0.8 V / 2 V thresholds - interoperates directly with 3 V and 5 V microcontrollers |
| Charge injection | −41 pC - limits voltage glitch to <1 mV in 1 nF sample-hold nodes |
| Off isolation | −78 dB at 100 kHz - suppresses crosstalk between adjacent channels in multi-channel DAQ |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | 1.8 Ω max RDS(on) at ±15 V; 16-lead TSSOP package; higher 120 ns tON | Lower thermal resistance (130 °C/W vs. 32 °C/W) limits continuous current in high-density layouts | Select when board space allows TSSOP and lower cost outweighs QFN thermal advantage |
| MAX4617ESE+ | 3.5 Ω RDS(on); ±15 V rated; 16-lead SOIC; no QFN option | Higher on-resistance increases insertion loss in 50 Ω RF paths; lacks 150 MHz bandwidth | Choose for legacy SOIC footprints where 1.5 Ω performance is non-critical |
Compared with ADG1412BRUZ and MAX4617ESE+, the DG1412EEN-T1-GE4 offers superior thermal performance (32 °C/W), lower on-resistance, and higher bandwidth - making it optimal for compact, high-channel-count, high-fidelity signal routing where PCB area and signal integrity are constrained.

FAQ
What is the maximum continuous switch current rating for DG1412EEN-T1-GE4 at +125 °C?
The DG1412EEN-T1-GE4 supports 100 mA maximum continuous switch current at +125 °C in its QFN-16 package, as specified in the Absolute Maximum Ratings table. This value reflects thermal derating due to junction-to-ambient thermal resistance of 32 °C/W. At 25 °C ambient, the limit rises to 250 mA. Always verify PCB copper area and airflow in final layout to maintain safe operating temperature.
Does DG1412EEN-T1-GE4 require a separate VL logic supply voltage?
No, DG1412EEN-T1-GE4 does not require a separate VL logic supply. Its digital inputs operate directly from the main V+ and GND rails with 0.8 V / 2 V logic thresholds, ensuring native compatibility with 3 V and 5 V microcontrollers without external level shifters. This simplifies power domain management in mixed-signal systems.
Is DG1412EEN-T1-GE4 pin-compatible with DG1411EEN-T1-GE4 or DG1413EEN-T1-GE4?
Yes, DG1412EEN-T1-GE4 shares identical QFN-16 pinout and package dimensions with DG1411EEN-T1-GE4 and DG1413EEN-T1-GE4. However, their switch configurations differ: DG1411E is normally closed (NC), DG1412E is normally open (NO), and DG1413E combines NC/NO pairs. Logic polarity and truth table behavior must be verified in firmware during substitution.
What is the guaranteed break-before-make timing for DG1412EEN-T1-GE4?
DG1412EEN-T1-GE4 does not guarantee break-before-make operation. That feature is explicitly specified only for DG1413E - which integrates internal timing control for guaranteed channel separation. DG1412EEN-T1-GE4 operates as independent SPST NO switches; simultaneous control of multiple channels requires external sequencing to avoid transient shorts.
Can DG1412EEN-T1-GE4 operate from a single +12 V supply while handling ±10 V analog signals?
No. When powered from a single +12 V supply (V− = GND), DG1412EEN-T1-GE4 supports analog signals from 0 V to +12 V only. To handle ±10 V signals, a dual supply (e.g., V+ = +12 V, V− = −12 V) is required - enabling true rail-to-rail operation from −12 V to +12 V. The device cannot swing below GND in single-supply mode.
