SN74ALS843 具有三态输出的 9 位总线接口 D 类锁存器

This 9-bit bus-interface D-type latch features 3-state outputs designed specifically for driving

highly capacitive or relatively low-impedance loads. It is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

The nine latches are transparent D-type latches with noninverting data (D) inputs.

A buffered output-enable () input places the nine 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 drive provide the capability to drive bus lines without interface or pullup components
