SN74LS273DW Octal D-Type Flip-Flop with Clear

The SN74LS273DW from Texas Instruments is a high-performance octal D-type flip-flop with clear functionality integrated into a single device. This integrated circuit (IC) is a member of the 74LS family, which is known for its low-power Schottky technology, making it a reliable choice for a wide range of digital applications. It is designed to be used in systems where high-speed, low-power operation is required.

Each flip-flop in the SN74LS273DW has a direct clear (CLR) input and a D-type data input. The device captures the state of the D inputs when the clock (CLK) input is in the high state, and these inputs are transferred to the Q outputs on the low-to-high transition of the CLK input. The clear function is synchronous, and a low level at the CLR input overrides all other inputs, setting the Q outputs low.

The SN74LS273DW comes in a wide-body SOIC (Small-Outline Integrated Circuit) package, which is ideal for space-constrained applications. The device is characterized for operation from 0°C to 70°C, ensuring reliable performance across a range of environmental conditions.

Key features of the SN74LS273DW include:

• Eight D-type flip-flops in a single package
• Direct clear input for all flip-flops
• Edge-triggered from a low-to-high transition of the clock pulse
• Wide operating voltage range of 4.75V to 5.25V
• Typical power dissipation of 200mW
• High noise immunity characteristic of LS logic families
• Output drive capability: 10 LS-TTL loads

Applications for the SN74LS273DW are diverse and include buffer storage, shift registers, data storage, and pattern generators, among other digital systems that require high-speed, reliable flip-flop operations. With its robust design and proven technology, the SN74LS273DW is a solid choice for designers looking to implement sequential logic in their digital circuits.

As with all Texas Instruments products, the SN74LS273DW is backed by a comprehensive set of technical documentation and support, ensuring that engineers can integrate this component into their designs with confidence and efficiency.
