SN74ABT273NS Octal D-Type Flip-Flop with Clear

The SN74ABT273NS from Texas Instruments is a high-performance, octal D-type flip-flop with clear functionality, designed to be utilized in a wide range of applications requiring the storage of eight bits of data. This integrated circuit is part of the ABT family, which is known for its advanced biCMOS technology, offering both high-speed operation and reduced power consumption compared to traditional CMOS and TTL logic families.

This device features eight edge-triggered D-type flip-flops with individual D inputs and Q outputs. The flip-flops capture the state of their respective D-inputs when the clock (CLK) input is on the rising edge, effectively storing the input data at that moment. The outputs Q will reflect the stored data when the clock input is in a stable state.

An important feature of the SN74ABT273NS is the asynchronous clear (CLR\) input. When CLR\ is set low, all eight flip-flops are cleared, and the Q outputs are driven low regardless of the states of the clock, data, or any other control inputs. This is particularly useful for initializing registers and counters in digital systems and ensuring a known startup state.

The SN74ABT273NS is housed in a 20-pin SOP (Small Outline Package) which is suitable for surface-mount technology, making it a compact and practical choice for densely packed PCBs (Printed Circuit Boards). The device operates over a broad voltage range and is characterized for operation from -40°C to 85°C, making it suitable for industrial applications.

Key features of the SN74ABT273NS include:

• Eight D-type flip-flops with single-rail outputs
• Asynchronous clear function for all flip-flops
• Edge-triggered clocking mechanism
• High-speed operation
• Reduced power consumption
• Wide operating temperature range
• Compact 20-pin SOP package for easy PCB integration

Whether used in data storage, buffer registers, or as part of more complex digital systems, the SN74ABT273NS provides a reliable and efficient solution for your digital logic needs.
