STMicroelectronics M74HCT273B1R Octal D-Type Flip-Flop
The M74HCT273B1R is a high-speed CMOS octal D-type flip-flop integrated circuit produced by STMicroelectronics. This device is designed for use in applications that require the capture and storage of eight bits of data in a synchronous manner. It is particularly well-suited for implementing buffer registers, control registers, and state machines in a wide range of digital systems.
Each flip-flop has a direct clear input and a clock input. The data on the D-input is transferred to the flip-flop output during the rising edge of the clock pulse. The clear input, when set to low, will immediately force all outputs to the low state, regardless of the clock input. This feature allows for rapid clearing of the flip-flops, which is essential for initializing or resetting digital circuits.
The M74HCT273B1R operates at a voltage range of 4.5V to 5.5V, making it compatible with TTL (Transistor-Transistor Logic) levels while offering the benefits of CMOS technology, such as reduced power consumption and increased noise immunity. This device also features a high fan-out capability, allowing it to drive multiple inputs without the need for additional buffering.
