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.
