The TS4604IPT from STMicroelectronics is a 4-channel line driver IC designed for analog signal transmission in professional audio and communication systems. Packaged in a 28-pin TSSOP and delivered in Tape & Reel (TR), this surface-mount device operates within a 3V to 4.8V supply range, making it suitable for low-power applications. Although marked as obsolete, it remains relevant for legacy designs due to its high-performance analog interface and ROHS3 compliance, ensuring environmental safety. With an MSL 1 (Unlimited) rating, it offers excellent moisture resistance during storage and handling.
The TS4604IPT excels in professional audio equipment, such as mixers, amplifiers, and broadcast systems, where low-noise analog signal integrity is critical. It is also well-suited for telecommunication infrastructure, including line drivers for modems and base stations, thanks to its multi-channel capability and stable voltage operation. Legacy industrial systems requiring reliable analog drivers may still leverage this IC for maintenance or retrofits.
While obsolete, the TS4604IPT remains a robust choice for analog line-driving applications demanding low-voltage operation, multi-channel support, and high reliability. Its compact TSSOP package and compliance with environmental standards make it a viable option for legacy designs or niche audio/communication systems. Engineers seeking alternatives should consider newer STMicroelectronics offerings, but for specific use cases, the TS4604IPT delivers proven performance.
