74FCT3573AQG

Latches Overview

The IDT 74FCT3573AQG is an octal transparent latch featuring three-state outputs, manufactured using FCT CMOS technology. It integrates eight D-type latches with a common latch enable (LE) and output enable (OE) control mechanism. The device operates within a supply voltage range of 2.0V to 3.6V, ensuring compatibility with standard logic families. It utilizes a 20-pin QSOP package for surface-mount applications.

Latches Feature Summary

• Provides eight independent transparent latch channels with true output polarity
• Features three-state outputs controlled by a dedicated output enable pin
• Utilizes FCT CMOS process technology for high-speed data storage operations

Latches Applications

• Data bus buffering in computer systems
• Memory address latching in embedded controllers
• I/O port expansion modules

Latches Procurement Notes

Verify the manufacturer designation on the datasheet, as IDT assets are managed by Renesas Electronics. Confirm the specific suffix 'G' indicates RoHS compliance and lead-free status according to the official product specification sheet. Ensure the package type matches the required QSOP-20 footprint for PCB layout integration.

Latches Selection Notes

Select this component when an octal latch with tri-state capability is required for 3.3V logic interfaces. The FCT series offers faster propagation delays compared to standard 74HC counterparts. Verify that the input voltage levels match the driving source logic family specifications before implementation.
