STV6412A集成電路（IC）的模擬開關(guān)-特殊用途規(guī)格書PDF中文資料

STV6412A屬于集成電路（IC）的模擬開關(guān)-特殊用途。由意法半導(dǎo)體集團制造生產(chǎn)的STV6412A模擬開關(guān) - 特殊用途特殊用途模擬開關(guān)通過固態(tài)設(shè)備路由模擬信號。該系列產(chǎn)品的與眾不同之處在于，這些模擬開關(guān)針對特定的應(yīng)用，因此具有通用模擬開關(guān)通常所沒有的獨特功能。

Description

The STV6412A is a highly integrated I2C bus-controlled audio and video switch matrix, optimized for use in digital set-top box applications. It provides all the audio and video routings required in a full two SCART set-top box design.
