MC74VHC1G125DFT1G集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

MC74VHC1G125DFT1G属于集成电路（IC）的缓冲器驱动器接收器收发器。由安森美半导体制造生产的MC74VHC1G125DFT1G缓冲器，驱动器，接收器，收发器逻辑缓冲器、驱动器、接收器和收发器允许隔离对某个电路的逻辑信号的访问，以用于另一电路。缓冲器将其输入信号（不变或反相）传递到其输出，并可能用于清除弱信号或驱动负载。在布尔逻辑仿真器中，缓冲器主要用于增加传播延迟。逻辑接收器和收发器允许在数据总线之间进行隔离通信。

Noninverting 3-State Buffer

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. The 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.
