74LV574N,112

Overview

The NXP 74LV574N,112 is an octal D-type flip-flop featuring positive edge triggering and three-state outputs. It operates within a supply voltage range of 1.0 V to 3.6 V, with specific optimization for low-voltage applications between 1.0 V and 3.6 V. The device accepts TTL input levels when the supply voltage is between 2.7 V and 3.6 V. It utilizes a standard DIP-20 plastic package and includes an active-low master reset (MR) input.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single package
• Positive edge-triggered data capture synchronized with clock transitions
• Three-state outputs allowing direct connection to bus lines without external drivers
• Active-low master reset function that clears all outputs simultaneously

Applications

• Parallel-to-serial data conversion circuits
• Bus interface modules requiring isolated data storage
• Digital signal processing systems utilizing 3.3 V logic levels
• Microcontroller peripheral expansion interfaces

Procurement Notes

Verify the exact ordering code matches the requested suffix. Confirm the package type corresponds to the required pin count and footprint. Ensure the voltage specifications align with the target system's power rails. Check for any specific environmental certifications required by the application standards.

Selection Notes

Select this component when an octal register with high-speed performance and low power consumption is needed. It is suitable for systems operating at 3.3 V where compatibility with 5 V TTL inputs is required. Consider the DIP-20 package if through-hole mounting is necessary for prototyping or specific mechanical constraints.

Part Context

This part belongs to the 74LV series, designed for low-voltage CMOS applications. It offers performance comparable to 74HC/HCT families but optimized for lower supply voltages. The series is widely used in portable electronics and battery-powered devices due to its energy efficiency and broad voltage tolerance.

FAQ

Does the 74LV574N,112 support 5 V operation?

No, the absolute maximum rating is typically 3.6 V. Operating at 5 V may damage the device.

How is the master reset function activated?

The master reset is activated by applying a low logic level to the MR pin, which asynchronously clears all Q outputs.
