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 (OE) 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 neit.
