M74HC123TTR集成電路（IC）的多諧振蕩器規(guī)格書PDF中文資料

M74HC123TTR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M74HC123TTR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觸頭等應用非常有用。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)轉換，該頻率通常也是由所連接電容器的值來確定。

DESCRIPTION

The M54/74HC123 is a high speed CMOS MONO-STABLE multivibrator fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.
