Overview
The CY74FCT2374ATSOC is an octal D-type flip-flop register manufactured by Texas Instruments within the FCT logic family. It features eight non-inverting data inputs and outputs with three-state control, housed in a 20-pin SOIC package. The device operates at a supply voltage range of 4.75 V to 5.25 V and supports TTL input levels. It is designed for surface-mount installation and functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Octal D-type flip-flop configuration providing eight independent storage elements
- Three-state output capability allowing bus line driving and isolation
- TTL-compatible input structure ensuring compatibility with standard logic families
Applications
- Parallel-to-serial data conversion circuits
- Buffering and latching operations in digital systems
- General-purpose memory storage applications
Procurement Notes
Verify component authenticity through authorized channels due to obsolete status. Confirm package integrity and pin alignment against datasheet specifications. Ensure storage conditions prevent moisture damage prior to soldering. Validate that substitute components meet identical electrical and mechanical requirements for system compatibility.
Selection Notes
Select this component for designs requiring octal data registration with high-speed performance characteristics. Consider the FCT series benefits for low power consumption and fast propagation delays. Evaluate thermal management needs given the wide operating temperature range. Assess board space constraints relative to the SOIC-20 footprint availability.
Part Context
This part belongs to the CY74FCT2374T series, representing advanced CMOS technology optimized for high-speed operation. It serves as a critical interface element between microprocessors and peripheral devices. The FCT family bridges the gap between traditional TTL and modern CMOS logic standards.
Replacement Considerations
Public confirmed substitutes include the CY74FCT2574ATSOC. Verify functional equivalence regarding pinout and electrical parameters before implementation.
