74LVC574ADB,112

Overview

The 74LVC574ADB,112 is a D-type edge-triggered flip-flop from the Nexperia 74LVC series. It contains one circuit with eight bits, featuring non-inverting three-state outputs. The device operates on a supply voltage range of 1.2 V to 3.6 V and supports a maximum clock frequency of 200 MHz. Propagation delay is specified at 3.2 ns at 3.3 V. Output drive capability is ±24 mA. It is housed in a 20-SOIC package and functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides eight-bit data storage with positive-edge triggering for synchronous digital applications.
• Features three-state outputs allowing direct bus line connections without external buffers.
• Supports mixed 3.3 V and 5 V environments through overvoltage tolerant inputs.

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• General-purpose memory storage elements

Procurement Notes

Verify the specific suffix '112' corresponds to the SOIC-20 package variant rather than other available packages like QFN or TSSOP. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding assembly sites or labeling updates before finalizing procurement orders.

Selection Notes

Select this component when an eight-bit latch with high-speed performance and three-state output control is required. Ensure the design accommodates the 1.2 V to 3.6 V supply range and verify that the 20-SOIC footprint matches the PCB layout constraints compared to alternative package options.

Part Context

This part belongs to the 74LVC574 family of octal D-type flip-flops. It shares functional compatibility with standard 74HC574 devices but offers improved speed and lower power consumption due to LVC technology. Other variants exist in different packages such as TSSOP and QFN, distinguished by their ordering suffixes.

Replacement Considerations
