Overview
The DG417BDY-T1 is a precision monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix. It operates within a dual supply range of ±15 V and supports single supplies up to 30 V. The device features a maximum on-resistance of 25 Ω at room temperature, with turn-on and turn-off times reaching 89 ns and 80 ns respectively under standard test conditions. It utilizes an SOIC-8 surface-mount package and functions across an industrial temperature range from -40 °C to +85 °C. Power dissipation is rated at 400 mW, and the unit draws a maximum supply current of 1 µA.
Feature Summary
- High-voltage silicon gate process ensures superior switching performance and latchup prevention.
- TTL and CMOS compatible logic control for simple interfacing.
- Low power consumption and low leakage currents suitable for battery-powered systems.
- Small physical size reduces board space requirements.
Applications
- Precision test equipment
- Precision instrumentation
- Battery powered systems
- Sample-and-hold circuits
- Military radios
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated by the suffix designation. Ensure storage and handling procedures adhere to ESD protection standards. Validate that the specific lot matches the required operating temperature range. Review datasheet revision history for any updates to electrical specifications.
Selection Notes
Select this component when high voltage ratings and low signal distortion are required. Compare on-resistance values against system impedance requirements. Evaluate thermal derating curves if operating near maximum power dissipation limits. Consider alternative packages such as MSOP-8 if footprint constraints exist. Verify logic level compatibility with the controlling microcontroller or FPGA.
Part Context
This part belongs to the DG417B series of precision analog switches. It shares functional similarities with the DG418B and DG419B, differing primarily in internal configuration and logic response. The DG417B specifically provides four independent SPST switches with complementary logic inputs. It is designed for applications requiring high performance in portable and industrial environments.
Replacement Considerations
Public confirmed substitute part numbers include DG417BDY-E3 and DG417BDQ-T1-E3. These variants offer identical electrical characteristics but differ in packaging type or environmental compliance suffixes. Verify pinout compatibility before substitution.
