Overview
The DG418DJ-E3 is a precision monolithic CMOS analog switch manufactured by Vishay Siliconix, housed in an 8-pin plastic MiniDIP package. It features a single SPST configuration with TTL and CMOS compatible logic control. The device operates on dual supplies ranging from ±5 V to ±20 V or a single supply up to 40 V. Key electrical specifications include a maximum on-resistance of 35 Ω, a turn-on time of 175 ns, and a turn-off time of 145 ns. It supports a continuous current of 30 mA and maintains low leakage currents within the -40 °C to +85 °C operating temperature range.
Feature Summary
- High-performance switching capability utilizing high voltage silicon gate process technology
- Low power consumption with ultra-low standby current requirements
- TTL and CMOS logic compatibility for simplified system interfacing
- Epitaxial layer construction ensuring latchup prevention
Applications
- Precision test equipment signal routing
- Battery powered industrial systems
- Sample-and-hold circuits
- Military radios and guidance systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Validate lot traceability and storage conditions prior to assembly. Ensure ordering suffixes match required packaging and environmental ratings.
Selection Notes
Select this component for applications requiring precise analog signal switching with minimal distortion. Verify that the 35 Ω on-resistance meets circuit impedance requirements. Confirm that the 175 ns switching speed aligns with system timing constraints. Ensure supply voltages remain within the specified ±20 V dual or 40 V single limits.
Part Context
This part belongs to the DG417/DG418/DG419 series of precision analog switches. The DG418 variant specifically provides a Normally Open (NO) SPST configuration, distinguishing it from the DG417 (NC) and DG419 (SPDT). It shares the same HVSG process technology and general performance characteristics as its siblings.
Replacement Considerations
DG417DJ-E3: Offers similar specs but with Normally Closed (NC) logic. DG419DJ-E3: Provides SPDT configuration instead of SPST. DG418DY-E3: Identical electrical function but utilizes SOIC-8 surface mount packaging.
