HCF4047B屬于集成電路（IC）的多諧振蕩器。由意法半導體集團制造生產(chǎn)的HCF4047B多諧振蕩器多諧振蕩器是簡單的雙態(tài)器件，盡管它們的典型使用方式在很大程度上具有模擬特性，但通常被認為是數(shù)字邏輯元器件。單穩(wěn)型也稱為“單發(fā)”，具有一種穩(wěn)定狀態(tài)；但施加觸發(fā)信號可使它們離開此狀態(tài)一段時間，該時間通常由所連接電容器的值來確定。這些器件對于去彈跳開關(guān)觸頭等應(yīng)用非常有用。非穩(wěn)型沒有穩(wěn)定狀態(tài)，在兩個狀態(tài)之間按一定頻率持續(xù)轉(zhuǎn)換，該頻率通常也是由所連接電容器的值來確定。

描述 Description

The HCC4000B series is composed of close to 80 monolithic types built with Metal Oxide Complementary technology. It provides Designers with high voltage noise tolerant complete Logic

series. It radiation hardness and immunity to Heavy Ions make this series to be usable in the

most difficult environmental conditions.
