CD74FCT573ATQM

Latches Overview

The CD74FCT573ATQM is an octal transparent latch manufactured by Harris Corporation. It features a single function with eight bits per element, providing tri-state outputs. The device operates within a supply voltage range of 4.5V to 5.5V and supports bidirectional data transmission. It is housed in a 20-lead QSOP package and is designed for high-speed CMOS logic applications requiring registered or real-time data multiplexing.

Latches Feature Summary

• Octal transparent latch configuration with D-type input structure
• Tri-state output capability for bus-oriented systems
• CMOS technology ensuring low power consumption and high noise immunity

Latches Applications

• Bus-oriented memory register implementations
• Temporary storage of digital data in processing systems
• Interface circuits between microprocessors and peripheral devices

Latches Procurement Notes

Verify the manufacturer origin, as Harris Semiconductor assets were acquired. Confirm RoHS compliance status, as original versions may not meet current environmental standards. Check for moisture sensitivity level (MSL) ratings if lead-free reflow soldering is required. Ensure the 20-QSOP package dimensions match your PCB footprint requirements before finalizing procurement.

Latches Selection Notes

Select this component when an octal latch with tri-state outputs is needed for 5V CMOS logic systems. Compare against the CD74HC573M for standard speed requirements or the CD74FCT651ATM for transceiver functionality. Consider the 20-QSOP package size constraints and ensure the operating temperature range meets your specific application environment.

Latches Part Context

This part belongs to the FCT series of high-speed CMOS logic devices produced by Harris Corporation. It serves as a fundamental building block for digital data storage and transfer. The device is related to other latches like the CD74AC563 and transceivers like the CD74HCT646M within the broader logic IC portfolio.

Latches Replacement Considerations

The CD74FCT573TQM is a documented substitute with identical pinout and functionality. Verify that any alternative from Texas Instruments or other manufacturers maintains the same 20-QSOP package and electrical characteristics.
