74LV574D,112

Overview

The NXP USA Inc. 74LV574D,112 is an octal D-type flip-flop featuring positive edge triggering and three-state outputs. It operates within a supply voltage range of 1V to 5.5V and utilizes a 20-SOIC package. The device supports a maximum clock frequency of 70 MHz and exhibits a propagation delay of 17ns at 5V with 50pF load capacitance. It provides output drive currents of 16mA for both high and low states, with a static current consumption of 160 µA. The component functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Octal D-type flip-flop architecture with positive edge-triggered data capture
• Three-state outputs allowing direct bus line connections without additional buffering
• Wide supply voltage operation from 1V to 5.5V for flexible system integration

Applications

• Parallel-to-serial data conversion in communication interfaces
• Register storage for microprocessor address and data buses
• Clock domain crossing synchronization circuits

Procurement Notes

Verify the specific suffix '112' against the manufacturer's official documentation to confirm tape and reel packaging specifications. Confirm RoHS compliance status and REACH registration details directly with NXP USA Inc. or authorized distributors. Ensure the procurement channel provides valid traceability records for this discontinued logic family component.

Selection Notes

Select this component when an octal register with three-state outputs is required for systems operating between 1V and 5.5V. The 70 MHz clock speed suits moderate-frequency digital logic applications. Consider the 20-SOIC package dimensions for PCB layout constraints. Evaluate thermal performance requirements given the extended industrial temperature range capability up to 125°C.
