It packs four independent transceivers into a single 100-LQFP package, operating from a 3.14 V to 3.47 V supply and drawing 230 mA typical. ## Temperature Grade and Environment Rated 0°C to 70°C, this is a commercial-temperature part. It fits indoor telecom equipment, central-office line cards, and controlled-environment racks. Not specified for outdoor or industrial cabinets without active cooling or extended-temperature qualification. ## Package and Assembly The 100-LQFP (14x14 mm body) is a hand-solderable SMD package. For production, a stencil and reflow profile are recommended; for rework or prototyping, a fine-tip iron and flux work. ## Lifecycle and Sourcing The DS21Q59L+ is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is indicated. For BOM planning, this part is suitable for new designs and ongoing production without near-term obsolescence risk.","metaTitle":"DS21Q59L+ E1 Transceiver, 100-LQFP, 3.3V, Active","metaDescription":"DS21Q59L+ is an active E1 transceiver IC in a 100-LQFP package.
