Overview
The DG401DY-T1 is a low-power, high-speed CMOS analog switch manufactured by Vishay Siliconix. It features two single-pole single-throw (SPST) switches in a 16-pin narrow SOIC package. The device supports a maximum supply voltage of 44 V and an analog signal range of ±15 V. Key electrical parameters include a typical on-resistance of 30 Ω with a maximum of 45 Ω at room temperature, rising to 55 Ω across the full operating temperature range. Turn-on time is typically 75 ns with a maximum of 150 ns, while turn-off time is typically 30 ns with a maximum of 100 ns. Leakage currents are extremely low, with off-leakage typically 0.01 nA and on-leakage typically 0.04 nA at room temperature. Power dissipation is rated at 600 mW for the SOIC package.
Feature Summary
- Break-before-make switching action guaranteed for SPDT configurations
- Compatible with TTL and CMOS logic levels
- Single supply capability with wide dynamic range
- Epitaxial layer prevents latchup
Applications
- Audio and video switching
- Sample-and-hold circuits
- Battery operation
- Test equipment
- Communications systems
Procurement Notes
Verify the specific suffix 'T1' indicates tape and reel packaging when sourcing components. Confirm RoHS compliance status based on the '-E3' designation if lead-free terminations are required for assembly processes. Ensure the ordering part number matches the exact package type and temperature range specified in the design documentation.
Selection Notes
Select this component for applications requiring low power consumption and fast switching speeds. The DG401 provides two independent SPST switches suitable for general-purpose analog signal routing. Consider the DG403 or DG405 variants if dual-pole double-throw or complementary switching functions are needed instead of simple single-pole single-throw control.
Part Context
The DG401 belongs to the DG40x series of low-power, high-speed CMOS analog switches from Vishay Siliconix. This series includes the DG401 (two SPST), DG403 (two DPST), and DG405 (four SPST). These devices share similar electrical characteristics and are designed for portable and battery-powered industrial and military applications due to their ultra-low power requirements.
Replacement Considerations
Direct functional replacements within the same family include DG401DJ, DG401DY-E3, and DG401DY-T1-E3. These alternatives offer identical pinouts and specifications but may differ in packaging format or RoHS compliance status.
