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.
does not affect the internal operation of the latches. Previously stored data can be retained or new data can be entered while the outputs are off.
The SN74ALS843 is characterized for operation from 0°C to 70°C.
