Additional Details

The TC74HC564F is available in a SOP-20 (Small Outline Package). Data is loaded into the flip-flops on the positive-going edge of the clock pulse. When the output enable (OE) input is LOW, the data from the flip-flops is present on the outputs. When OE is HIGH, the outputs are in a high-impedance state. The device utilizes CMOS technology for low power consumption and high noise immunity.

The supply voltage range is typically between 2V and 6V. The setup and hold times for the data inputs must be met to ensure reliable operation. The device is designed to be compatible with other HC series logic devices.
