74FCT3573QG

Latches Overview

The IDT 74FCT3573QG is an octal transparent latch manufactured using advanced low-power CMOS technology. It features eight D-type latches with true outputs and three-state control, designed for high-speed data storage applications in 3.3V systems. The device operates within the FCT logic family, providing balanced drive capabilities and compatibility with industry-standard pinouts. It supports industrial temperature ranges and includes hysteresis on inputs to enhance noise immunity during signal transitions.

Latches Feature Summary

• Octal transparent latch configuration with true outputs
• Three-state output control for bus isolation
• Advanced low-power CMOS construction
• Industrial operating temperature range support

Latches Applications

• High-speed data buffering in digital systems
• Interface bridging between 5V and 3.3V logic domains
• Temporary data storage in microprocessor-based designs

Latches Procurement Notes

Verify the specific suffix 'Q' against official manufacturer documentation to confirm package type and environmental compliance status. Ensure the component matches the required lead-free or RoHS specifications for your assembly process. Cross-reference the manufacturer part number with current Renesas or IDT catalogs to confirm availability and revision levels before procurement.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is required for 3.3V logic applications. It is suitable for designs needing high-speed data retention and bus isolation. Consider its compatibility with LVC class products if voltage translation from 5V sources is necessary. Verify that the package style meets the PCB layout constraints of the target design.

Latches Part Context

This component belongs to the FCT series of fast CMOS logic devices produced by Integrated Device Technology. The series is characterized by high speed and low power consumption, making it suitable for demanding digital applications. IDT was later acquired by Renesas Electronics, which continues to support these legacy logic families in their product portfolio.

Latches Replacement Considerations

Compatible substitutes include the PI74FCT3573 from Pericom Semiconductor, which offers similar electrical characteristics and pinout compatibility. Other generic equivalents within the 74FCT3573 family may be considered if they meet the specific voltage and speed requirements of the application.
