Overview
The DG412LDQ-T1 is a precision monolithic quad SPST low-voltage CMOS analog switch manufactured by Vishay Siliconix. It operates on single supplies from 2.7 V to 12 V or dual supplies from ±3 V to ±6 V. The device features a maximum drain-source on-resistance of 33 Ω at ±5 V and typical turn-on/turn-off times of 19 ns and 12 ns respectively. It offers low leakage current (0.25 nA), TTL and CMOS compatibility, and 2000 V ESD protection. Packaged in a 16-pin TSSOP with an operating temperature range of -40 °C to +85 °C.
Feature Summary
- Low voltage operation compatible with single and dual power supplies
- Fast switching speeds with minimal insertion loss
- TTL and CMOS logic interface compatibility
- High off-isolation and channel-to-channel crosstalk performance
Applications
- Precision automatic test equipment
- Precision data acquisition systems
- Audio and video signal routing
- Communication systems including DSL and DSLAM
- Battery powered portable systems
Procurement Notes
Verify the specific suffix 'T1' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status as standard manufacturing may vary. Ensure the D suffix temperature rating (-40 °C to +85 °C) matches application requirements. Validate pinout alignment for the 16-pin TSSOP package during PCB layout.
Selection Notes
Select this component for applications requiring low voltage operation and fast switching. Compare against DG411L for opposite control logic or DG413L for mixed normally open/closed configurations. Verify that the 33 Ω on-resistance meets signal integrity requirements at the target supply voltage.
Part Context
This part belongs to the DG411L/DG412L/DG413L family of low-voltage analog switches. These devices are designed as pin-for-pin compatible upgrades to the industry-standard DG411/DG412/DG413 series, offering improved performance through BiCMOS wafer fabrication technology.
Replacement Considerations
DG411LDQ-T1 provides identical specifications but with inverted control logic. DG413LDQ-T1 offers mixed normally open and closed switch configurations within the same package.
