The SN74LVC16374A is particularly suitable for
implementing buffer registers, I/O ports, bidirectional
bus drivers, and working registers. The device can be
used as two 8-bit flip-flops or one 16-bit flip-flop. On
the positive transition of the clock (CLK) input, the Q
outputs of the flip-flop take on the logic levels set up
at the data (D) inputs.
A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high or
low logic levels) or the 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.
