The 74HC273D,653 from Nexperia is an octal D-type edge-triggered flip-flop with active-low clear in a 20-pin SOIC package. Eight data inputs are clocked into the flip-flops on the rising edge of CLK, providing parallel data storage with synchronous output.<\/p>\n

On the rising edge of CLK, the D inputs are transferred to Q outputs. The active-low CLR input asynchronously clears all Q outputs to LOW regardless of CLK. This provides 8-bit parallel register functionality for data latching, address holding, and output staging in digital systems.<\/p>\n
