SN74ALS580B 具有三态输出的八路 D 类透明锁存器
These octal D-type transparent latches feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
While the latch-enable (LE) input is high, outputs (Q\) respond to the data (D) inputs. When LE is low, the outputs are latched to retain the data that was set up.
A buffered output-enable 
input can be used to place the eight outputs in either a normal logic state (high or low) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and the increased drive provide the capability to drive bus lines without interface or pullup components
