SN54ALS563B 具有三态输出的八路 D 类透明锁存器
These 8-bit 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, the Q outputs follow the complements of data (D) inputs. When LE is taken low, the outputs are latched at the inverses of the levels set up at the D inputs.
A buffered output-enable (OE)\ input places the eight outputs in either a normal logic state (high or low logic levels) 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 increased high logic level provide the capability to drive bus lines without interface or pullup components
