SN74ACT534NSR

Flip Flops Overview

The SN74ACT534NSR is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments, belonging to the ACT logic series. It features three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device provides a propagation delay of 11.5 ns at 5 V with maximum capacitive load. Output drive capability includes 24 mA low-level and -24 mA high-level currents. It is housed in a 20-pin SOIC package and supports through-hole or surface-mount installation styles depending on variant, with an operating temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops for parallel data storage
• Three-state outputs allowing direct connection to bus systems without external buffers
• Edge-triggered operation synchronized by clock signals for precise timing control
• ACT series technology ensuring compatibility with standard TTL input levels

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Bus interface buffering and isolation
• Digital signal processing data registers
• Microprocessor memory address latching

Flip Flops Procurement Notes

Verify the specific suffix NSR indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status via the manufacturer's current documentation. Ensure the design accommodates the 20-pin SOIC footprint and thermal requirements for the industrial temperature range. Cross-reference pinouts with the official datasheet to prevent integration errors during PCB layout.

Flip Flops Selection Notes

Select this component when eight-bit synchronous storage with tri-state output control is required. The ACT series offers improved speed over standard 74LS equivalents while maintaining CMOS power efficiency. Consider the 11.5 ns propagation delay for timing budget analysis. Verify that the 5 V supply voltage aligns with the system architecture before finalizing the bill of materials.

Flip Flops Part Context

This part belongs to the SN74ACT534 family of octal flip-flops. It serves as a digital storage element in complex logic designs. The NSR suffix denotes the reel-packaged version suitable for automated assembly processes. It complements other ACT series components like latches and drivers in comprehensive logic solutions.

Flip Flops Replacement Considerations

SN74ACT534N is the tube-packaged equivalent with identical electrical characteristics. SN74ACT534DR is the alternative SOIC-20 reel option from Texas Instruments. Verify pin compatibility and electrical specs before substituting with non-TI manufacturers.
