The LVC823A 9-bit bus-interface flip-flop is built using advanced dual metal CMOS technology. The LVC823A device is designed specifically for driving highly capacitive or relatively low-impedance loads. The device is particularly suitable for implementing wider buffer registers, I/O ports, bidirectional bus drivers with parity, and working registers. With the clock-enable (CLKEN) input low, the nine D-type edge-triggered flip-flops enter data on the low-to-high transitions of the clock. Taking CLKEN high disables the clock buffer, latching the outputs. This device has noninverting data (D) inputs. Taking the clear (CLR) input low causes the nine Q outputs to go low, independently of the clock. A buffered output-enable (OE) input can be used to place the nine outputs in either a normal logic state (high or low logic levels) or a high-impedance state. OE does not affect internal operations of the latch. Previously stored data can be retained or new data can be entered while the outputs are in the high-impedance state.
