The innovative Le57D121 dual-channel SLIC device is designed for high-density POTS applications requiring a small-footprint, low-power SLIC device. By combining a fully featured line interface of two channels into one SLIC device, the Le57D121 device enables the design of a low-cost, high performance, and fully programmable line interface for multiple country applications worldwide, including Ground Start and metering capability. The on-chip Thermal Management (TMG) feature allows for significantly reduced power dissipation on the device. Optional dual battery operation to reduce total power consumption is also available. The device is offered in a thermally efficient, space-saving 44-pin eTQFP package. The 12 x 12 mm footprint allows designers to make a dramatic increase in the density of lines on a board. The Le57D121 device is also designed to significantly reduce the number of external components required for line card design. Microchip offers a range of compatible SLAC devices that perform the codec function in a line card. In particular, the Quad and Octal SLAC devices combined with the Le57D121 device provides a programmable line circuit that can be configured for varying requirements.
YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
LE57D121 is an authentic electronic component manufactured by Microchip, categorized under Unclassified. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official LE57D121 datasheet above.
Electronic component spot-market pricing for LE57D121 fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for LE57D121 depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
