HD74LS273P (74LS273)
Description:
The HD74LS273P is an octal D-type flip-flop with eight positive-edge-triggered flip-flops in a single package. Each flip-flop stores a single bit of data, and data inputs (D) are latched into the flip-flops on the rising edge of the clock (CLK) signal. This IC is commonly used in digital electronics for data storage, synchronization, and control applications.
