CY74FCT2374TSOCTG4

Overview

The CY74FCT2374TSOCTG4 is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting D-type latches with a single clock input and three-state outputs. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum clock frequency of 250 MHz. It utilizes TTL-compatible inputs and provides low static current consumption. Packaged in a 20-SOIC (0.295 inch / 7.50 mm width) surface-mount housing, it functions as a registered bus transceiver or data latch for high-speed digital applications.

Feature Summary

• Octal D-type flip-flop architecture with single clock control
• Three-state outputs for bus-oriented memory operations
• TTL-compatible inputs ensuring interface flexibility
• High-speed performance supporting up to 250 MHz clock frequencies

Applications

• Bus-oriented memory register implementations
• 250-MHz clocked data latch circuits
• High-speed buffered registers in digital systems
• Registered bus transceivers requiring TTL compatibility

Procurement Notes

Verify the specific suffix 'TG4' indicates RoHS compliance and lead-free construction when sourcing. Confirm the package variant matches the required SOIC-20 footprint dimensions. Ensure the supplier provides official datasheets confirming the 250 MHz operational limit. Cross-reference the manufacturer part number against authorized distributors to avoid counterfeit components. Check for any specific handling requirements related to moisture sensitivity levels during storage.

Selection Notes

Select this component for designs requiring octal data storage with high-speed switching capabilities. The FCT series offers a balance between speed and power consumption suitable for 5V logic systems. Consider the three-state output feature if bus sharing is necessary. Verify that the TTL-compatible input thresholds align with the driving source logic family. Evaluate the thermal performance within the specified operating temperature range for the target application environment.

Part Context

This part belongs to the CY74FCT374T family, which includes functionally compatible variants like the CY74FCT374TSOC. The 'C' in the base model typically denotes tube packaging, while 'T' indicates tape and reel. The 'G4' suffix specifically designates Green product status with lead-free pins and solder bump composition. This lineage ensures pinout compatibility with earlier FCT devices while offering improved electrical characteristics.

Replacement Considerations

The CY74FCT374TSOC is a functionally equivalent alternative within the same family. Both parts share identical pinouts and logical operations. Verify that the replacement package type meets the PCB layout constraints. Ensure the substitute component maintains the required 250 MHz speed rating. Confirm that the RoHS status of the replacement matches environmental compliance requirements.
