- Communication systems including SDSL and DSLAM
- Audio and video signal routing
Procurement Notes
Verify the specific ordering suffix against the manufacturer's documentation to confirm the exact package type and temperature range. Ensure that the component meets all required environmental standards and RoHS compliance specifications before finalizing procurement orders.
Selection Notes
Select this component when low voltage operation between 2.7 V and 12 V is required. Consider the 17 Ω on-resistance and fast switching speeds for high-frequency applications. Verify that the SOIC-16 package dimensions fit the target PCB layout constraints.
Part Context
This part belongs to the DG441L/DG442L series of low-voltage CMOS analog switches. It serves as a companion device to industry-standard switches with improved performance characteristics using BiCMOS fabrication technology.

FAQ
What is the break-before-make switching characteristic?
The device ensures that one switch opens before another closes, preventing momentary short circuits during signal path transitions.
How does the DG441LDY-T1 handle input signals exceeding supply rails?
Internal diodes clamp signals on Sx, Dx, or INx that exceed V+ or V-, limiting forward diode current to maximum ratings.
