CY74FCT2574TSOCG4

Overview

The CY74FCT2574TSOCG4 is an octal D-type register manufactured by Texas Instruments, belonging to the FCT logic series. It features three-state outputs and is housed in a 20-SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a wide operating temperature range from -40°C to +85°C. Key electrical parameters include a propagation delay of 6.5 ns at 5 V, with high-level output current capability of -15 mA and low-level output current of 12 mA.

Feature Summary

• Octal D-type register architecture providing eight independent data storage channels
• Three-state outputs enabling direct connection to bus systems without external buffers
• CMOS technology ensuring low static power consumption and high noise immunity

Applications

• Parallel-to-serial data conversion interfaces
• Bus-oriented memory register applications
• Clocked buffer and latch circuits for system synchronization

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and environmental adherence as per manufacturer specifications. Confirm the SOIC-20 package dimensions match the target PCB footprint requirements. Ensure the component meets the required operating temperature range for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring octal data latching with bus-compatible three-state outputs. Consider the 6.5 ns propagation delay for timing constraints and the 15 mA/12 mA drive currents for load requirements. Verify compatibility with the 4.75 V to 5.25 V supply voltage range and ensure the SOIC-20 package fits the available board space.

Part Context

This part belongs to the Texas Instruments CY74FCT2574T family of octal D-type registers. The 'G4' suffix denotes a lead-free product variant compliant with RoHS standards. It is functionally similar to other devices in the FCT series but offers specific packaging and environmental attributes defined by the manufacturer's production guidelines.
