Overview
The DG442LEDY-T1-GE3 is a monolithic quad single-pole-single-throw (SPST) normally open analog switch manufactured by Vishay Siliconix. It operates on single supplies from 3 V to 16 V or dual supplies of ± 3 V to ± 8 V. The device features a typical on-resistance of 16 Ω, fast turn-on time of 18 ns, and low charge injection under 8 pC. It is housed in a 16-pin narrow body SOIC package with a tape and reel quantity of 2500 units.
Feature Summary
- Low parasitic capacitance for minimized switching glitches
- TTL and CMOS logic compatible inputs
- High off-isolation and channel-to-channel crosstalk performance
Applications
- Data acquisition systems
- Sample-and-hold circuits
- ADC input circuit designs
- Automatic test equipment
Procurement Notes
Verify the specific ordering suffix T1-GE3 against official documentation to confirm the tape and reel packaging format and RoHS compliance status. Ensure the component matches the required 16-pin SOIC physical dimensions and thermal characteristics for the target printed circuit board layout.
Selection Notes
Select this part when a normally open configuration is required for high-speed signal routing. Compare the 16 Ω on-resistance and 18 ns switching speed against system requirements. Verify that the 650 mW power dissipation rating accommodates the expected load current within the operating temperature range.
Part Context
This component belongs to the DG441LE/DG442LE family of low charge injection switches. The DG442 variant specifically provides a normally open function, contrasting with the DG441's normally closed design. Both share identical electrical specifications and package options within the series.

FAQ
What is the default state of the DG442LE switches?
The DG442LE devices feature a normally open configuration, meaning the switches are off when the logic input is low.
How does the DG442LE handle signals exceeding supply levels?
Signals on the source or drain terminals exceeding the supply rails will be clamped by internal diodes.
