TLC59212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TLC59212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。

3 Description

The TLC59212 device is an 8-bit open-collector driver

with latch designed for 5-V VCC operation.

These circuits are positive-edge-triggered D-type flipflops

with a direct clear (CLR) input. Information at

the data (D) input meeting the setup time

requirements is transferred to the Y output 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 has no effect at the output.

The TLC59212 is characterized for operation from –40°C to 85°C.
