Overview
The DG401BDJ is a low-power, high-speed CMOS analog switch manufactured by Vishay Siliconix. It contains two independent single-pole single-throw (SPST) switches housed in a 16-pin plastic dual-in-line package. The device supports a maximum supply voltage of 44 V and an analog signal range of ±15 V. Key electrical parameters include a maximum on-resistance of 45 Ω at room temperature and up to 55 Ω across the full operating temperature range. Turn-on time is typically 100 ns with a maximum of 150 ns, while turn-off time is typically 60 ns with a maximum of 100 ns. The device operates within a temperature range of -40 °C to +85 °C.
Feature Summary
- Features fast switching speeds combined with low power consumption for portable applications
- Provides TTL and CMOS logic compatibility for simple interfacing
- Supports single supply capability alongside dual supply operation
Applications
- Audio and video switching
- Sample-and-hold circuits
- Test equipment
- PBX and PABX systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the physical marking matches the specified part number and package type. Review the official datasheet for absolute maximum ratings to ensure operational limits are not exceeded during integration.
Selection Notes
Select this component when designing circuits requiring two independent SPST analog switches. Ensure the application voltage does not exceed the 44 V maximum rating. Verify that the required switching speed and leakage current specifications align with the documented performance characteristics for the intended operating temperature range.
Part Context
This component belongs to the DG401B series, which serves as an upgrade to the original DG401/403/405 analog switches. The B-series variants offer improved performance metrics, specifically combining high speed with low power consumption. The product line includes complementary parts such as the DG403B and DG405B, which feature different internal switch configurations.
Replacement Considerations
The lead-free commercial version designated as DG401BDJ-E3 is available as a direct replacement. Both versions share identical functional specifications and pinouts.
