U74HCT374

DESCRIPTION 

The U74HCT374 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.
