Overview
The 54FCT573CTLB is an octal transparent D-type latch manufactured by Renesas Electronics Corporation. It features eight D-type latches with tri-state outputs, designed for high-speed data storage and bus interfacing applications. The device operates within a supply voltage range of 4.5V to 5.5V and utilizes a 20-lead LCC package measuring 8.89x8.89mm. It supports surface mount technology and is characterized by low input and output leakage currents, ensuring CMOS power levels while maintaining true TTL compatibility.
Feature Summary
- Octal transparent D-type latch configuration with tri-state outputs
- True TTL input and output compatibility
- Low input and output leakage currents
- CMOS power consumption levels
Applications
- High-speed data storage systems
- Bus interface circuits
- Register files in digital logic designs
- Memory buffer applications
Procurement Notes
Verify the specific grade (Std., A, or C) required for your application, as performance characteristics may vary between grades. Confirm the 20-LCC package dimensions match your PCB footprint constraints. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure supply chain availability as this component belongs to the legacy FCT series.
Selection Notes
Select this component when an octal latch with tri-state capability is needed for TTL-compatible interfaces. The 54FCT573CTLB offers a compact 20-LCC surface mount solution suitable for space-constrained designs. Consider the operating temperature range and propagation delay specifications relative to your system speed requirements. Compare against other FCT series variants if different packaging or electrical characteristics are preferred.
Part Context
This part belongs to the 54/74FCT573T family of octal transparent latches. It shares functional similarities with other variants like the 54FCT573CTDB but differs in package type, utilizing a 20-lead LCC instead of a CDIP. The FCT series is known for combining CMOS low power with TTL compatibility, making it suitable for mixed-logic environments.
Replacement Considerations
The 54FCT573CTDB is a documented substitute part number offering identical logical functionality in a 20-CDIP package. Verify pinout compatibility and package dimension differences before substitution. Other FCT573 variants may serve as alternatives depending on specific grade and packaging requirements.
