The SN74HC273DWR is an integrated circuit (IC) component designed for use in digital systems. It belongs to the 74HC family of high-speed CMOS logic devices. The SN74HC273DWR functions as an octal D flip-flop with a common clock and asynchronous clear.
Key Features:
1. Octal D flip-flop: The SN74HC273DWR consists of eight D-type flip-flops. These flip-flops can store a single bit of data each, making it suitable for applications requiring a large number of storage elements.
2. Common clock input: The IC has a single clock (CLK) input that controls the data transfer into the flip-flops. When a positive clock edge is detected, the input data is latched into the respective flip-flops. This allows synchronized and controlled storage of data.
3. Asynchronous clear input: The SN74HC273DWR features an asynchronous clear (CLR) input, which overrides the clock and asynchronously resets all flip-flops. When active low, CLR sets all the outputs to a cleared state, regardless of the clock input. This feature allows for quick and immediate resetting of the outputs if needed.
4. Schmitt-trigger inputs: The IC incorporates Schmitt-trigger inputs, which provide hysteresis and help minimize noise-induced glitches. This ensures reliable and stable operation in noisy environments by reducing false triggering caused by input noise
