Overview
The DG470EQ-T1-E3 is a high voltage single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It features an enable pin for safe state control and operates with dual supplies of ±4.5 V to ±15 V or a single supply up to 12 V. The device provides a typical on-resistance of 3.6 Ω and supports analog signal ranges extending to the supply rails. Key electrical parameters include a maximum turn-on time of 166 ns, a maximum turn-off time of 108 ns, and a charge injection of 58 pC at room temperature. It is housed in an 8-pin MSOP package.
Feature Summary
- Includes an enable input that forces both switch sides into a high impedance mode when activated, ensuring a safe state during power-up or fault conditions.
- Guarantees break-before-make switching action to prevent momentary shorting between channels during transitions.
- Supports TTL/CMOS compatible logic thresholds with low voltage inputs for digital control compatibility.
Applications
- Audio and video signal switching
- Precision automatic test equipment
- Relay replacement
- Sample and hold systems
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and compliance status. Ensure the component meets the required operating temperature range and supply voltage specifications for the target application before finalizing procurement.
Selection Notes
Select this component for applications requiring high voltage handling and precise signal routing. The enable pin makes it suitable for systems needing a defined off-state. Compare on-resistance and leakage current requirements against the datasheet limits to ensure performance adequacy.
Part Context
This part belongs to the DG469/DG470 family of high voltage SPDT analog switches. While functionally identical to the DG469, the DG470 variant specifically includes an enable pin for additional control over the switch state.

FAQ
What is the primary difference between the DG469 and DG470?
The DG470 includes an enable input pin that allows the switch to be forced into a high impedance state, whereas the DG469 does not have this feature.
Does the DG470 support single supply operation?
Yes, the device can operate with a single supply voltage up to 12 V, as well as dual supplies ranging from ±4.5 V to ±15 V.
What is the maximum analog signal range?
The analog signal range extends to the supply voltage rails, allowing signals to swing from V- to V+.
