Overview
The DG419LDY-E3 is a single-channel SPDT analog switch manufactured by Vishay Siliconix, housed in an SOIC-8 surface-mount package. It operates with dual supply voltages of ±15 V and supports single supplies up to 30 V. The device features a maximum on-resistance of 18.5 Ohms, a maximum power dissipation of 400 mW, and a maximum supply current of 1 µA. Switching performance includes a maximum turn-on time of 41 ns and a maximum turn-off time of 32 ns. It handles a DC switch current of 30 mA and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Single-pole double-throw (SPDT) configuration for signal routing
- Low power consumption with 1 µA maximum supply current
- High-speed switching capabilities suitable for dynamic applications
- Compliant with RoHS directives for environmental safety
Applications
- Data acquisition systems requiring signal multiplexing
- Instrumentation circuits needing precise analog signal path control
- Communication equipment utilizing analog switching functions
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix indicates lead-free compliance and tube packaging. Check for end-of-life status as discontinuation may affect long-term availability. Ensure storage conditions meet semiconductor handling standards to prevent moisture sensitivity issues prior to soldering.
Selection Notes
Select this component when a single SPDT switch with ±15 V dual supply capability is required. Compare on-resistance values against system loss requirements, noting the 18.5 Ohm maximum. Consider the SOIC-8 footprint constraints during PCB layout. Evaluate thermal dissipation limits relative to ambient temperature and current load to ensure operation within the specified junction temperature range.
Part Context
This part belongs to the DG series of analog switches from Vishay Siliconix. It shares functional similarities with other members like the DG419DY-E3 but differs in specific electrical parameters such as on-resistance and switching speed. The 'LDY' designation typically denotes specific manufacturing lot or revision characteristics within the SOIC-8 package family.
Replacement Considerations
DG419DY-E3 offers similar SPDT functionality but with different resistance and speed specifications. DG419BDY-E3 provides higher voltage tolerance with distinct switching times. Verify pin compatibility and parameter alignment before substituting these alternatives.
