MC74VHC1GT125屬于集成電路（IC）的緩沖器驅(qū)動器接收器收發(fā)器。由安森美半導體公司制造生產(chǎn)的MC74VHC1GT125緩沖器，驅(qū)動器，接收器，收發(fā)器邏輯緩沖器、驅(qū)動器、接收器和收發(fā)器允許隔離對某個電路的邏輯信號的訪問，以用于另一電路。緩沖器將其輸入信號（不變或反相）傳遞到其輸出，并可能用于清除弱信號或驅(qū)動負載。在布爾邏輯仿真器中，緩沖器主要用于增加傳播延遲。邏輯接收器和收發(fā)器允許在數(shù)據(jù)總線之間進行隔離通信。

The MC74VHC1G125 / MC74VHC1GT125 is a single

non?inverting 3?state buffer in tiny footprint packages. The

MC74VHC1G125 has CMOS?level input thresholds while the

MC74VHC1GT125 has TTL?level input thresholds.

The internal circuit is composed of three stages, including a buffered

3?state output which provides high noise immunity and stable output.

The input structures provide protection when voltages up to 5.5 V

are applied, regardless of the supply voltage. This allows the device to

be used to interface 5 V circuits to 3 V circuits. Some output structures

also provide protection when VCC = 0 V and when the output voltage

exceeds VCC. These input and output structures help prevent device

destruction caused by supply voltage ? input/output voltage mismatch,

battery backup, hot insertion, etc.
