74FCT573ATDB

Latches Overview

The Renesas Electronics Corporation 74FCT573ATDB is an octal transparent D-type latch featuring tri-state outputs. It operates within a supply voltage range of 4.75V to 5.25V and supports a propagation delay of 1.5ns. The device provides high drive capability with output currents of 15mA (high) and 48mA (low). It is housed in a 20-CDIP package and functions reliably across an operating temperature range of -40°C to +85°C.

Latches Feature Summary

• Octal transparent latching architecture for parallel data storage
• Tri-state non-inverted outputs for bus-driven applications
• High current drive capability supporting direct interface loads

Latches Applications

• Parallel data buffering in digital systems
• Bus-oriented memory register structures
• Clock domain crossing synchronization circuits

Latches Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status and check for End-of-Life notifications, as discontinuation notices may affect long-term availability. Ensure the specific package variant matches design requirements before procurement.

Latches Selection Notes

Select this component when an octal latch with tri-state control is required for high-speed logic applications. Consider the 20-CDIP package constraints for through-hole mounting. Evaluate the 5V operation requirement against system power rails and ensure thermal management aligns with the specified industrial temperature range.

Latches Part Context

This part belongs to the 74FCT logic family, designed for fast CMOS performance. It serves as a standard octal latch solution for replacing older TTL-based designs. The AT designation typically indicates specific speed and drive characteristics within the FCT series lineup.

Latches Replacement Considerations

Publicly confirmed substitute part numbers include CY74FCT573ATSOC and CY74FCT573ATSOCT from Texas Instruments.
