MC14099BDWR2集成电路（IC）的锁存器规格书PDF中文资料

MC14099BDWR2属于集成电路（IC）的锁存器。由安森美半导体制造生产的MC14099BDWR2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 MC14099B is an 8−bit addressable latch. Data is entered in serial form when the appropriate latch is addressed (via address pins A0, A1, A2) and write disable is in the low state. For the MC14099B the input is a unidirectional write only port.

The data is presented in parallel at the output of the eight latches independently of the state of Write Disable, Write/Read or Chip Enable.

A Master Reset capability is available on both parts.
