DESCRIPTION/ORDERING INFORMATION
The SN74LVC574A octal edge-triggered D-type flip-flop is designed for 2.7-V to 3.6-V VCC operation.
This device features 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. It is 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 at the data (D) inputs.
