It handles physical-layer encoding, jitter attenuation, and line driving/receiving for digital trunk lines. The 44-TQFP package keeps the board footprint compact for multi-port line cards. ## Supply range and current — sizing the rail The DS2148T+ operates from a 4.75 V to 5.25 V supply. Typical supply current is 95 mA. ## Temperature grade — indoor telecom only Rated for 0°C to 70°C commercial temperature range, this part is intended for controlled indoor environments like equipment rooms, central offices, and climate-controlled cabinets. Not suitable for outdoor, industrial, or automotive applications without additional thermal management. ## Lifecycle and compliance — active, no LTB risk The DS2148T+ is listed as Active with ROHS3 compliance. For new designs and production builds, this part carries no imminent obsolescence risk.","metaTitle":"DS2148T+ Line Interface Unit, 44-TQFP, 5V Supply","metaDescription":"Maxim Integrated DS2148T+ telecom LIU in 44-TQFP. 4.75V to 5.25V supply, 95 mA typical, 0°C to 70°C.
