74LVC574AD,112

Overview

The 74LVC574AD,112 is a D-type edge-triggered flip-flop manufactured by Nexperia USA Inc. It features one circuit with eight bits per element, housed in a 20-SOIC package. The device operates on a supply voltage range of 1.2 V to 3.6 V. It exhibits a maximum propagation delay of 3.2 ns at 3.3 V with a 50 pF load. Output drive capability is specified at -24 mA for both high and low states. Static current consumption is typically 10 µA. The component supports surface-mount installation and functions within an operating temperature range of -40 °C to +125 °C.

Feature Summary

• Positive-edge triggered data transfer mechanism
• Three-state non-inverting output configuration
• High noise immunity via Schmitt trigger inputs
• 5 V tolerant input/output levels

Applications

• Parallel data storage registers
• Shift register construction
• Bus-oriented memory systems
• Timing control circuits

Procurement Notes

Verify the specific suffix '112' against manufacturer documentation to confirm the exact tape-and-reel quantity and packaging format. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity. Cross-reference the ordering code with the latest Nexperia product data sheet to avoid substitution errors.

Selection Notes

Select this component when a single eight-bit latch with three-state outputs is required in a standard SOIC-20 footprint. It is suitable for designs needing 5 V tolerance while operating from lower voltage supplies. Consider the 3.2 ns propagation delay for timing constraints. Verify that the thermal performance of the SOIC package meets the application's power dissipation requirements under maximum load conditions.

Part Context

This part belongs to the 74LVC family of logic integrated circuits, designed for low-voltage CMOS applications. The 74LVC574 variant specifically provides octal D-type flip-flops with three-state outputs. The 'AD' designation indicates the SOIC-20 plastic package, while ',112' specifies the standard reel packaging configuration used for automated surface-mount assembly processes.

Replacement Considerations

The 74LVC574AD,118 serves as a direct functional replacement offering identical electrical characteristics but utilizes a different tape-and-reel packaging specification. Both parts share the same core logic functionality and pinout compatibility within the 74LVC series.
