Overview
The IDT54FCT821HCTEB is a FAST CMOS bus interface register manufactured by Integrated Device Technology Inc. It is classified as a logic integrated circuit, specifically a flip-flop element bit within the BCT/FBT series. The device features a single functional unit with ten bits per element and provides true output polarity. It utilizes BICMOS technology and operates within an extended temperature range from -55 °C to 125 °C. The component is housed in a ceramic metal-sealed cofired package with 28 terminals, designated as LCC-28 or QCCN.
Feature Summary
- Implements FAST CMOS bus interface register functionality for high-speed data handling
- Utilizes BICMOS technology for robust signal integrity
- Provides true output polarity for direct logic interfacing
Applications
- High-speed data bus registration
- System memory interface control
- Peripheral data buffering
Procurement Notes
Verify the specific manufacturer designation, as IDT assets are managed by Renesas Electronics Corporation. Confirm the package type matches the required LCC-28 footprint and ensure the operating temperature range meets system requirements. Check compliance status regarding RoHS directives, as historical documentation may indicate non-compliant variants. Validate pinout compatibility before integration into existing designs.
Selection Notes
Select this component when a 10-bit bus interface register with true output is required. Ensure the design supports the specified 28-terminal ceramic package dimensions. Consider the extended temperature rating for industrial or automotive environments. Verify that the FAST CMOS speed characteristics align with the target system clock frequencies and signal timing constraints.
Part Context
This part belongs to the BCT/FBT series of logic devices, which are designed for high-performance bus applications. The IDT54FCT821HCTEB serves as a specialized flip-flop element bit, distinct from standard drivers or receivers. Its classification under logic circuits highlights its role in sequential data storage and transfer within complex digital systems.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official Renesas Electronics catalogs for cross-reference options.
