Product details

The supply voltage spans 2.25V to 3.6V, so the same part can serve a 2.5V FPGA bank or a 3.3V microcontroller without a separate regulator.

The 6-VDFN exposed pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm. A single via under the pad to the ground plane is sufficient for most layouts; for high-vibration environments, add a grid of vias to improve mechanical adhesion. Surface-mount assembly follows standard reflow profiles for lead-free solder. The package is RoHS-compliant per Microchip's standard material declaration.

Availability is confirmed per RFQ through independent distribution.

Frequently asked questions

Is the DSC1121AL2-041.5000T compatible with 3.3V logic?

Yes. The 2.25V to 3.6V supply range includes 3.3V, and the CMOS output swings rail-to-rail, so it directly drives 3.3V logic inputs without external level shifting.

What is the closest pin-compatible alternative to the DSC1121AL2-041.5000T?

Within the same DSC1121 series, other frequency variants share the same 6-VDFN package and pinout. For a 41.5 MHz part, the DSC1121AL2-041.5000T is the standard offering; no direct second-source is listed, but the base product number DSC1121 covers the family. Confirm pin compatibility with the datasheet before substitution.
