74LVQ573SC

Latches Overview

The Fairchild Semiconductor 74LVQ573SC is a high-speed octal transparent latch featuring buffered common Latch Enable (LE) and Output Enable (OE) inputs. It operates within a voltage range of 1.65V to 3.3V, utilizing CMOS technology in a 20-SOIC package. The device provides eight D-type latches with three-state outputs, designed for low-voltage applications requiring high performance and reduced power consumption.

Latches Feature Summary

• High-speed operation suitable for demanding digital systems
• Buffered control inputs for improved signal integrity
• Three-state outputs for efficient bus driving
• Low voltage compatibility for modern electronic designs

Latches Applications

• Data storage in microprocessor-based systems
• Bus-oriented memory architectures
• Clock buffering and timing circuits
• Portable battery-powered devices

Latches Procurement Notes

Verify the specific suffix 'SC' indicates the 20-SOIC package variant. Confirm RoHS compliance status as historical data may vary. Check for obsolescence notices from ON Semiconductor, which acquired Fairchild's logic business. Ensure supply chain authenticity through authorized distributors only.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is required for low-voltage logic families. Compare propagation delays against other LVQ series variants if speed is critical. Ensure the SOIC-20 footprint matches the PCB layout constraints. Verify input voltage levels align with the system's logic standards.

Latches Part Context

This part belongs to the LVQ series of low-voltage logic devices, offering enhanced performance over standard LV/LVT counterparts. It serves as a direct replacement for older octal latches in legacy designs transitioning to lower voltage supplies. The device maintains pin compatibility with similar industry-standard latch configurations.

Latches Replacement Considerations

Consider the 74LVQ573D or 74LVQ573N for alternative packaging options such as DIP or TSSOP. Verify electrical specifications match exactly before substituting. Check for updated datasheets from ON Semiconductor regarding any parameter revisions.
