SN74F377AN屬于集成電路（IC）的觸發(fā)器。由美國德州儀器公司制造生產(chǎn)的SN74F377AN觸發(fā)器觸發(fā)器是能夠存儲單個(gè)邏輯狀態(tài)或信息“位”的基本數(shù)字存儲器件。這些器件至少有兩個(gè)輸入；一個(gè)或多個(gè)用于傳遞要存儲的數(shù)據(jù)，另一個(gè)用于指示存儲該數(shù)據(jù)的時(shí)間點(diǎn)。不同的觸發(fā)器類型，例如 D（延遲）、SR（置位復(fù)位）和 JK，對提供給其輸入的信號有不同的響應(yīng)，可用于實(shí)現(xiàn)不同的邏輯功能。這些器件與鎖存器的不同之處在于它們是邊緣敏感器件，其保持的邏輯狀態(tài)僅在接收到有效時(shí)鐘信號時(shí)才會改變。

description

The SN74F377A is a monolithic, positive-edge-triggered, octal, D-type flip-flop with clock enable inputs. The

SN74F377A features a latched clock enable (CE) input.

Information at the data (D) inputs meeting the setup time requirements is transferred to the Q outputs on the

positive-going edge of the clock pulse if CE is low. Clock triggering occurs at a particular voltage level and is

not directly related to the positive-going pulse. When the clock input is at either the high or low level, the D input

signal has no effect at the output. The circuits are designed to prevent false clocking by transitions at the CE

input.

The SN74F377A is characterized for operation from 0°C to 70°C.
