74LVT574BQ,115

Overview

The 74LVT574BQ,115 is an octal D-type flip-flop manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2.7 V to 3.6 V and features three-state outputs. The device utilizes a 20-VFQFN package with exposed pad for surface mount installation. It supports a maximum clock frequency of 200 MHz and exhibits a propagation delay of 2.5 ns at 3.3 V. The component provides high drive capability with output currents of ±32 mA and maintains low static current consumption.

Feature Summary

• Octal D-type flip-flop architecture with positive-edge triggering
• Three-state outputs enabling direct bus line connections
• High-speed operation supporting up to 200 MHz clock frequencies
• Robust output drive strength of ±32 mA

Applications

• Parallel-to-serial data conversion circuits
• Buffering and register applications in digital systems
• Clock domain crossing synchronization stages
• Data acquisition system input/output interfaces

Procurement Notes

Verify the manufacturer designation as Nexperia USA Inc., reflecting the corporate separation from NXP Semiconductors. Confirm the specific suffix ,115 corresponds to the 20-VFQFN package variant. Ensure compliance with RoHS3 standards and check for any recent Product Change Notifications regarding assembly sites or labeling updates prior to finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring an octal storage element with high-speed performance under 3.3 V logic levels. The 200 MHz capability makes it suitable for high-frequency data handling tasks. Consider the 2.5 ns propagation delay for timing-critical paths. The exposed pad thermal design should be accounted for during PCB layout to ensure adequate heat dissipation and electrical grounding.

Part Context

This part belongs to the 74LVT logic family, designed for low-voltage applications. It serves as a digital storage element within complex integrated circuit designs. The device complements other logic components such as buffers and decoders in standard digital signal processing architectures. Its specifications align with industry-standard TTL/CMOS compatibility requirements for modern electronic equipment.
