CY74FCT2374CTSOCE4

Overview

The CY74FCT2374CTSOCE4 is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the FCT logic series. It features positive edge triggering and true outputs with three-state capability. The device operates on a single power supply ranging from 4.75V to 5.25V. It is housed in a 20-SOIC package suitable for surface mount installation. The component supports a wide operating temperature range from -40°C to 85°C. It includes an output enable input for controlling data flow. The static current consumption is specified at 100 µA. Propagation delay is typically 10 ns under standard load conditions.

Feature Summary

• Octal D-type flip-flop architecture with positive edge triggering
• Three-state outputs controlled by an active-low enable input
• CMOS construction within the FCT logic family for high-speed performance
• True output polarity providing non-inverted data transmission

Applications

• Parallel-to-serial data conversion circuits
• Register file storage elements in digital systems
• Data bus buffering and isolation stages
• Timing synchronization and clock domain crossing

Procurement Notes

Verify the specific suffix E4 indicates lead-free compliance and RoHS standards before procurement. Confirm the SOIC-20 package dimensions match the target PCB footprint. Ensure the supply voltage matches the 4.75V to 5.25V requirement. Check for any obsolescence notices or lifecycle status changes from the manufacturer. Validate that the enable pin logic level aligns with the system control signals.

Selection Notes

Select this component when an octal register with tri-state outputs is required for high-speed CMOS applications. The FCT series offers faster switching speeds compared to standard LS logic while maintaining compatible pinouts. Consider the 20-SOIC package for space-constrained surface mount designs. Evaluate the 100 µA static current against power budget constraints. Ensure the operating temperature range meets the environmental requirements of the final assembly.

Part Context

FAQ

What is the function of the OE pin?

The OE (Output Enable) pin controls the state of the outputs. When low, the outputs are active; when high, they enter a high-impedance state.

Is the output inverted or non-inverted?

The outputs are true, meaning they are non-inverted relative to the D inputs.

What triggers the data capture?

Data is captured on the positive-going transition of the clock signal.
