STMicroelectronics M74HC273TTR Octal D-Type Flip-Flop with Clear

The M74HC273TTR from STMicroelectronics is a high-speed CMOS octal D-type flip-flop with clear, encapsulated in a space-saving TSSOP-20 package. This integrated circuit is designed for use in applications requiring the capture and storage of eight bits of data simultaneously. It is a member of the high-speed CMOS family and offers a robust combination of speed, performance, and power efficiency.

The device features eight edge-triggered flip-flops with individual D-type inputs and Q outputs. The common clock (CP) and master reset (MR) inputs allow for synchronous control of all flip-flops. The reset input is active high and, when applied, will set all outputs to the low state, irrespective of the clock input. This makes the M74HC273TTR ideal for interfacing with microprocessors or microcontrollers where clear and precise data handling is crucial.

Each flip-flop is designed to change state on the rising edge of the clock signal, ensuring reliable and predictable data storage. The input and output structures provide high noise immunity and the ability to drive heavy loads, making this device suitable for a wide range of digital applications, including buffer storage, shift registers, data storage, and more.

The M74HC273TTR operates over a wide voltage range from 2V to 6V and features low power dissipation with a maximum ICC of 80 µA when not switching. This low power consumption, combined with the high noise immunity of balanced propagation delays, makes this flip-flop a practical choice for battery-operated devices and other power-sensitive applications.

With its robust design, the M74HC273TTR ensures latch-up performance that exceeds 100mA per JESD 78, Class II, and it also complies with JEDEC standard no. 7A requirements. The device is also ESD protected, ensuring a high level of protection against static discharge which is critical for maintaining the integrity of the data and the longevity of the component in various operating environments.

Overall, the M74HC273TTR from STMicroelectronics represents a reliable and efficient solution for designers looking to implement octal D-type flip-flops with clear functionality in their digital systems.
