SN74AC574NSRE4

Flip Flops Overview

The SN74AC574NSRE4 is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 2V to 6V. The device utilizes CMOS input technology and provides non-inverting logic polarity. Key electrical specifications include a maximum propagation delay of 13.5ns at 5V with 50pF load, and output drive capabilities of ±24mA. It is housed in a 20-pin TSSOP package suitable for surface-mount applications.

Flip Flops Feature Summary

• Octal configuration containing eight independent D-type edge-triggered flip-flops
• Three-state outputs allowing direct bus-driven connections without external buffers
• CMOS input structure compatible with standard logic families
• Wide operating supply voltage range from 2V to 6V

Flip Flops Applications

• Parallel data storage and buffering in digital systems
• Bus-oriented memory register implementations
• Clock domain crossing synchronization circuits
• High-speed data latch applications requiring low power consumption

Flip Flops Procurement Notes

Verify the E4 suffix indicates lead-free status and RoHS compliance per manufacturer standards. Confirm the NSR designation corresponds to the TSSOP-20 surface-mount package variant. Ensure the component meets industrial temperature ranges if applicable to the specific design environment. Cross-reference the datasheet revision date to confirm current electrical characteristics and pinout configurations before finalizing procurement.

Flip Flops Selection Notes

Select this component when designing systems requiring octal latching with high-speed performance and wide voltage flexibility. The AC series offers superior speed compared to HC variants while maintaining low power dissipation. Consider the TSSOP package for space-constrained PCB layouts. Evaluate the ±24mA output drive strength against load requirements to ensure signal integrity across the bus architecture.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74AC574 family of octal D-type flip-flops. The AC series represents advanced CMOS technology providing faster switching speeds than standard HC logic. The E4 suffix typically denotes environmental compliance modifications, such as lead-free plating, while maintaining identical functional specifications to the base SN74AC574NSR model.

Flip Flops Replacement Considerations

SN74AC574NSR serves as the primary equivalent without the environmental suffix. SN74ACT574N offers TTL-compatible inputs with similar performance but different input thresholds. SN74HC574N provides a slower, lower-cost alternative with wider voltage tolerance. Verify pin compatibility and electrical parameters before substituting any cross-family components.
