STMicroelectronics M74HC273B1R Octal D-Type Flip-Flop

The M74HC273B1R is a high-speed CMOS octal D-type flip-flop integrated circuit produced by STMicroelectronics, a leader in semiconductor solutions. This device is designed to meet the stringent requirements of modern digital systems, providing a reliable and efficient way to store data bits. The M74HC273B1R is particularly suitable for applications that require the capture and retention of multiple data lines simultaneously.

Constructed with silicon gate CMOS technology, the M74HC273B1R offers the benefit of high-speed operation while maintaining the low power dissipation characteristic of CMOS circuitry. This makes it an ideal choice for battery-powered and energy-saving applications. The device has eight edge-triggered, D-type flip-flops with individual D inputs and Q outputs. The common clock (CP) and master reset (MR) inputs control all flip-flops.

The M74HC273B1R operates with a supply voltage range of 2V to 6V, which is compatible with TTL levels. This allows for easy integration with existing TTL systems, as well as with other high-speed CMOS logic families. The device is capable of driving 10 LSTTL loads, ensuring compatibility with a wide range of digital components and systems.

The flip-flops will store the state of their individual D inputs that meet the setup and hold time requirements on the LOW-to-HIGH clock (CP) transition. A HIGH on the MR input sets all flip-flops to the low state, regardless of the clock input or the D inputs. This synchronous reset feature is critical for initializing registers and control circuits that require a clear and predictable start state.

STMicroelectronics packages the M74HC273B1R in a 20-pin plastic DIP, making it suitable for through-hole mounting on printed circuit boards. Its robust design ensures reliable operation over a wide temperature range, making it a versatile choice for industrial, commercial, and consumer applications where data storage integrity is paramount.

In summary, the M74HC273B1R from STMicroelectronics is a versatile and reliable component for digital systems requiring octal D-type flip-flops. With its high-speed performance, low power consumption, and compatibility with various logic levels, it represents a valuable building block for a wide array of electronic designs.
