About this manual

The TEF6894H is a monolithic BiMOS integrated circuit that combines a stereo decoder, weak‑signal processing, noise blanking, input selection and tone/volume control for car radio applications. It operates from a supply voltage of 8 V to 9 V and communicates via a fast‑mode I²C bus.

The datasheet provides detailed functional descriptions, pin assignments, electrical characteristics, package information (QFP44, 44‑lead), and recommended soldering methods for surface‑mount assembly.
