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 ’HCT374 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.

6D  
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.
