SN74AC573DWR集成电路（IC）的锁存器规格书PDF中文资料

SN74AC573DWR属于集成电路（IC）的锁存器。由德州仪器制造生产的SN74AC573DWR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。

1 Features

• Operation of 2 V to 6 V V CC

• Inputs accept voltages to 6 V

• Maximum tpd of 9 ns at 5 V

• 3-State outputs drive bus lines directly

2 Applications

• Buffer registers

• Bidirectional bus drivers

• Working registers

3 Description

These 8-bit latches feature 3-state outputs designed

specifically for driving highly capacitive or relatively

low-impedance loads. The devices are particularly

suitable for implementing buffer registers, I/O ports,

bidirectional bus drivers, and working registers.
