description/ordering information  
These 8-bit flip-flops feature 3-state outputs designed specifically for driving highly capacitive or relatively  
low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional  
bus drivers, and working registers.  
The eight flip-flops of the ’HC374 devices are edge-triggered D-type flip-flops. On the positive transition of the  
clock (CLK) input, the Q outputs are set to the logic levels that were set up at the data (D) inputs.  
An output-enable (OE) input places 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.
