74LCX573SJX

Latches Overview

The Fairchild Semiconductor 74LCX573SJX is a low-voltage CMOS octal transparent D-type flip-flop featuring three-state outputs. It operates within a supply voltage range of 2.0V to 3.6V and supports 5V tolerant inputs and outputs, facilitating direct interfacing with 5V systems. The device utilizes an advanced CMOS technology designed for high-speed operation while maintaining low power consumption. It is housed in a 20-pin SOP package.

Latches Feature Summary

• Features eight D-type flip-flops with transparent latch functionality controlled by a single enable pin.
• Provides three-state outputs to manage bus line driving and prevent signal contention.
• Incorporates 5V tolerant I/O structures allowing safe interface between 3.3V logic and 5V peripherals.

Latches Applications

• High-performance register files
• Bus-oriented memory mapping
• Clock buffering

Latches Procurement Notes

Verify the specific suffix 'SJX' against official onsemi/Fairchild documentation to confirm the exact tape-and-reel packaging configuration and lead-free status. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number with current distributor catalogs to confirm active lifecycle status and availability.

Latches Selection Notes

Select this component when designing systems requiring low-voltage (3.3V) operation with mixed-voltage interfaces. It is suitable for applications demanding high-speed data latching and bus isolation. Consider the 20-SOP package constraints regarding board space and thermal dissipation compared to TSSOP alternatives.

Latches Part Context

This component belongs to the 74LCX series of low-voltage CMOS logic devices. The series is characterized by compatibility with standard 5V TTL/CMOS environments despite lower operating voltages. The 74LCX573 specifically addresses the need for high-density data storage and transfer in portable and battery-powered electronic equipment.

Latches Replacement Considerations

Direct substitutes include MC74LCX573DWG and MC74LCX573DWR2G from onsemi. Verify that replacement packages match the required footprint and pinout compatibility before integration.
