概要

Description

The SN74HC273DWR is an octal D-type flip-flop with a direct clear function, produced by Texas Instruments as part of the 74HC logic family. It operates with a wide voltage range from 2V to 6V, making it suitable for various applications in digital circuits. Each flip-flop within the IC features a data (D) input, a clock (CLK) input, and a complementary Q output.
Data present at the D input is transferred to the Q output on the positive edge of the clock pulse, provided the clear (CLR) input is high. When CLR is low, the outputs are reset to a low logic level regardless of other inputs, allowing for asynchronous reset operations.
The SN74HC273DWR is commonly used in applications requiring data storage, data latching, and state retention, like registers and memory devices. It comes in a 20-pin SOIC (Small Outline Integrated Circuit) package, suitable for surface-mount technology, which supports efficient space usage on printed circuit boards. The device is known for its low power consumption and high-speed operation, compatible with TTL logic levels.
