The is a 10-bit Bus Interface Flip-flop with 3-state outputs. It is designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing wider buffer registers, I/O ports, bidirectional bus drivers with parity and working registers. On the positive transition of the clock CLK input, the devices provide true data at the Q outputs. A buffered OE\ input can be used to place the ten 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 need for interface or pull-up components. OE\ does not affect the 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.
