SN74AHC574N

Flip Flops Overview

The SN74AHC574N is an octal edge-triggered D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 5.5V and features non-inverting logic. The device supports a maximum clock frequency of 115 MHz and exhibits a typical propagation delay of 10.6ns at 5V with 50pF load. It is housed in a 20-pin PDIP package suitable for through-hole mounting, with an operating temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single package
• Three-state outputs capable of driving bus lines directly
• High-speed performance with low propagation delay characteristics
• Wide operating voltage range supporting 2V to 5.5V supply rails

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Bus interface buffering and latching applications
• Digital signal processing data storage stages
• Microprocessor system address and data latching

Flip Flops Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm package type and temperature grade. Ensure the selected variant matches the required 20-pin PDIP form factor. Confirm RoHS compliance status if environmental regulations apply to the design. Cross-reference the pinout diagram with the target PCB footprint to prevent installation errors during assembly.

Flip Flops Selection Notes

Select this component when designing systems requiring wide voltage compatibility between 2V and 5.5V. The high switching speed makes it suitable for applications exceeding standard 74HC series performance limits. Consider the 3-state output capability for shared bus architectures where multiple devices must share data lines without electrical contention or interference.

Flip Flops Part Context

This part belongs to the SNx4AHC574 family of octal edge-triggered D-type flip-flops. It shares functional similarities with the SN74HC574N but offers improved speed and broader voltage operation. The AHC series represents an advancement over standard HC logic, providing faster transition times while maintaining CMOS power efficiency characteristics for modern digital designs.

Flip Flops Replacement Considerations

SN74HC574N offers similar functionality with lower speed and narrower voltage range. SN74ACT574N provides comparable performance but requires strict 5V supply constraints. SN74AS574N delivers higher drive current but operates only at 5V. Verify pin compatibility and electrical specifications before substituting any alternative logic family member.
