STMicroelectronics M74HCT273M1R Octal D Flip-Flop

The M74HCT273M1R is a high-speed CMOS octal D-type flip-flop integrated circuit produced by STMicroelectronics. This device is designed to meet the stringent requirements of modern electronic systems, providing a reliable and efficient solution for data storage and transfer applications. The M74HCT273M1R is particularly suitable for implementing buffer registers, shift registers, and state machines, thanks to its eight edge-triggered D-type flip-flops with clear (reset) input.

Each flip-flop features a dedicated D-input (data input) and Q-output (output), along with a shared asynchronous clear input that, when activated, resets all flip-flops simultaneously. This clear function is active low, meaning it is triggered when a logic low voltage is applied. The flip-flops are triggered on the rising edge of the clock input, ensuring precise timing for data capture.

The M74HCT273M1R operates with a wide supply voltage range from 4.5V to 5.5V, making it compatible with TTL (Transistor-Transistor Logic) levels while maintaining the low power consumption and high noise immunity inherent to CMOS technology. This versatility allows the device to be used in mixed 5V and 3.3V environments, interfacing seamlessly with both CMOS and TTL logic levels without the need for additional level-shifting components.

Encased in a compact SO-20 package, the M74HCT273M1R is designed for surface-mount technology (SMT), allowing for efficient use of PCB (Printed Circuit Board) space and facilitating automated assembly processes. Its small form factor and high functionality make it an excellent choice for space-constrained applications.
