SN74LX574PW Octal Edge-Triggered D-Type Flip-Flops from Texas Instruments

The SN74LX574PW is a high-performance, octal edge-triggered D-type flip-flop integrated circuit from Texas Instruments, designed for use in a wide range of digital applications. This device features eight D-type flip-flops with 3-state outputs and is ideal for temporary storage of data, buffering, and data flow control in digital systems.

Each flip-flop is triggered on the low-to-high transition of the clock (CLK) input while a clear (CLR) input sets all outputs low when taken to a low logic level. The SN74LX574PW boasts a wide operating voltage range of 2V to 3.6V, making it suitable for interfacing with both 3.3V and 2.5V logic levels. This flexibility ensures compatibility with a variety of modern microprocessors and digital systems.

The device is housed in a 20-pin TSSOP (Thin Shrink Small Outline Package) that offers a compact footprint for space-constrained applications. The SN74LX574PW is characterized for operation from -40°C to 85°C, ensuring reliable performance over a broad range of ambient temperatures.

Key features of the SN74LX574PW include:

• Eight edge-triggered D-type flip-flops with individual D inputs and Q outputs.
• 3-state outputs for bus-oriented applications.
• Wide operating voltage range of 2V to 3.6V.
• Direct clear (CLR) input for all flip-flops.
• Low power consumption with a typical ICC of only 20 μA maximum.
• High drive capability with -24 mA IOH and 24 mA IOL.
• Edge-triggered clock input for precise timing control.

The SN74LX574PW is designed with Texas Instruments' advanced silicon-gate CMOS technology, which provides a robust and low-power solution for high-speed data storage and transfer. Its 3-state outputs can drive bus lines or buffer memory address registers, and its fast propagation delay times make it an excellent choice for high-speed applications.

Whether you're designing data storage, communication systems, or need reliable flip-flops for buffering purposes, the SN74LX574PW offers a perfect blend of performance, power efficiency, and versatility to meet your design requirements.
