description
The SN74ACT16374Q-EP is a 16-bit
edge-triggered D-type flip-flop with 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.
This 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.
An output-enable (OE) input can be used to place the 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 provides the capability to drive bus lines in a bus-organized system,
without need for interface or pullup components. OE does not affect the internal operations of the flip-flop. Old
data can be retained or new data can be entered while the outputs are in the high-impedance state.
