74ACT373集成电路（IC）的锁存器规格书PDF中文资料

74ACT373属于集成电路（IC）的锁存器。由安森美半导体公司制造生产的74ACT373锁存器锁存器是类似于触发器的基本数字存储设备，但是不同之处在于，在锁存使能（或类似命名）信号处于有效逻辑状态的任何时间，保持的逻辑状态都可以改变。“透明”锁存器还允许设备输出在锁存使能信号有效时反映输入的当前状态，而相反的是，状态仅在保持状态已固定时改变。

The MC74AC373/74ACT373 consists of eight latches with 3–state outputs for bus organized system applications. The flip–flops appear transparent to the data when Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup time is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH, the bus output is in the high impedance state.

• Eight Latches in a Single Package

• 3–State Outputs for Bus Interfacing

• Outputs Source/Sink 24 mA

• ′ACT373 Has TTL Compatible Inputs
