description/ordering information

The ’AHC374 devices are octal edge-triggered D-type flip-flops that feature 3-state outputs designed

specifically for driving highly capacitive or relatively low-impedance loads. These devices are particularly

suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

On the positive transition of the clock (CLK) input, the Q outputs are set to the logic levels of 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) 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 the increased drive provide the capability to drive bus lines without

interface or pullup components.
