Overview
The DG418DY-T1 is a precision CMOS analog switch manufactured by Vishay Siliconix, housed in an 8-pin narrow SOIC package. It features a single SPST configuration with a maximum on-resistance of 35 Ω and a turn-on time of up to 175 ns. The device supports dual supply voltages ranging from ±5 V to ±20 V and operates within a temperature range of -40 °C to +85 °C. Built using high-voltage silicon gate (HVSG) process technology, it offers ultra-low power consumption with a typical power dissipation of 35 nW.
Feature Summary
- High-performance switching utilizing HVSG process for superior voltage ratings
- Ultra-low power requirements suitable for battery-powered applications
- TTL and CMOS compatible logic control levels
Applications
- Precision test equipment
- Sample-and-hold circuits
- Battery powered systems
Procurement Notes
Verify the specific suffix 'T1' indicates tape and reel packaging when sourcing components. Confirm RoHS compliance status as datasheets may contain both compliant and non-compliant variants. Ensure the ordering code matches the exact pinout and electrical specifications required for the target circuit design.
Selection Notes
Select this component for designs requiring low leakage and minimal board space. Verify that the 35 Ω maximum on-resistance meets signal integrity requirements. Check if the 44 V absolute maximum supply rating aligns with system voltage constraints.
Part Context
This part belongs to the DG417/DG418/DG419 family of monolithic CMOS analog switches. While sharing similar manufacturing processes and core technologies, the DG418 differs from the DG417 by having opposite control logic levels and from the DG419 by lacking break-before-make switching action.

FAQ
What is the logic sense of the DG418?
The DG418 responds to opposite control logic levels compared to the DG417; Logic '0' turns the switch off, and Logic '1' turns it on.
Does the DG418 support break-before-make switching?
No, break-before-make switching is guaranteed only for the DG419 model within this series.
