U74AHC374

DESCRIPTION 

The U74AHC374 is a octal edge-triggered D-type flip-flops with 

3-state outputs and it has 8 channels. 

When the OE input is low, on the positive transition of the clock 

(CLK) input, the Q outputs are set to the logic levels of the data (D) 

inputs. 

When the OE input is high, the outputs are in the high-impedance.

To ensure the high-impedance state during power up or power 

down, OE should be tied to VCC through a pull-up resistor; the 

minimum value of the resistor is determined by the current-sinking 

capability of the driver.
