MC14538BD集成電路（IC）的多諧振蕩器規(guī)格書(shū)PDF中文資料

MC14538BD屬于集成電路（IC）的多諧振蕩器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC14538BD多諧振蕩器多諧振蕩器是簡(jiǎn)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(rèn)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(hào)可使它們離開(kāi)此狀態(tài)一段時(shí)間，該時(shí)間通常由所連接電容器的值來(lái)確定。這些器件對(duì)于去彈跳開(kāi)關(guān)觸頭等應(yīng)用非常有用。非穩(wěn)型沒(méi)有穩(wěn)定狀態(tài)，在兩個(gè)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(lái)確定。

The MC14538B is a dual, retriggerable, resettable monostable multivibrator. It may be triggered from either edge of an input pulse, and produces an accurate output pulse over a wide range of widths, the duration and accuracy of which are determined by the external timing components, CX and RX. Output Pulse Width T = RX ? CX (secs)

RX = Ω

CX = Farads
