Overview
The CY74FCT16823ATPACT is an 18-bit D-type flip-flop manufactured by Texas Instruments. It features positive-edge triggering and three-state outputs for bus-oriented memory operations. The device operates within a supply voltage range of 4.75 V to 5.25 V. It is housed in a 56-pin TSSOP package with a width of 0.240 inches (6.10 mm). The component supports a wide operating temperature range from -40°C to +85°C, ensuring reliable performance in industrial environments.
Feature Summary
- Provides 18-bit data storage capability via D-type flip-flops
- Features positive-edge clock triggering for precise timing control
- Includes three-state outputs to facilitate efficient bus driving
- Compatible with standard TTL input levels
Applications
- Bus-oriented memory register implementations
- High-speed data buffering applications
- Parallel-to-serial conversion circuits
- Industrial control system data latching
Procurement Notes
Verify the specific suffix 'TPACT' corresponds to the TSSOP package and tape-and-reel delivery format when sourcing. Confirm that the manufacturer designation aligns with Texas Instruments specifications. Ensure the component meets the required thermal and electrical standards for the intended operational environment before finalizing procurement orders.
Selection Notes
Select this component for designs requiring high-density 18-bit parallel data storage with minimal pin count. The TSSOP package offers space efficiency for surface-mount applications. Consider the propagation delay characteristics relative to system clock speeds. Ensure power supply stability within the specified 4.75 V to 5.25 V range to maintain signal integrity.
Part Context
This part belongs to the CY74FCT logic family, known for CMOS technology with TTL-compatible inputs. It serves as a critical element in digital systems requiring reliable data retention. The 18-bit configuration distinguishes it from standard octal or hex variants, providing expanded capacity in a single integrated circuit package for complex data handling tasks.
Replacement Considerations
The CY74FCT16823T is a related variant within the same series. Verify package compatibility and lead configuration equivalence before substitution. Ensure functional parameters match the original design requirements.
