SN74ALS273集成電路（IC）的觸發(fā)器規(guī)格書(shū)PDF中文資料

SN74ALS273屬于集成電路（IC）的觸發(fā)器。由德州儀器制造生產(chǎn)的SN74ALS273觸發(fā)器觸發(fā)器是能夠存儲(chǔ)單個(gè)邏輯狀態(tài)或信息“位”的基本數(shù)字存儲(chǔ)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(chǔ)的數(shù)據(jù)，另一個(gè)用于指示存儲(chǔ)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(duì)提供給其輸入的信號(hào)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(hào)時(shí)才會(huì)改變。

description

These octal positive-edge-triggered flip-flops

utilize TTL circuitry to implement D-type flip-flop

logic with a direct-clear (CLR) 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

(CLK) pulse. Clock triggering occurs at a particular

voltage level and is not directly related to the

transition time of the positive-going pulse. When

CLK is at either the high or low level, the D input

signal has no effect at the output.

The SN54ALS273 is characterized for operation

over the full military temperature range of –55°C

to 125°C. The SN74ALS273 is characterized for

operation from 0°C to 70°C.
