Description
General part information
SN74ALS843 Series
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.
