Procurement Notes

Verify the specific suffix 'CTDB' against official Integrated Device Technology documentation to confirm package type (CDSO) and military-grade temperature rating (-55°C to 125°C). Ensure compatibility with MIL-STD-883 Class B requirements if applicable. Cross-reference pinouts and electrical characteristics with the latest datasheet to avoid confusion with commercial variants.

Selection Notes

Select this component for applications requiring high-speed octal latching with tri-state capabilities. Consider the FCT series advantages over standard FAST logic, including faster propagation delays and lower power consumption. Verify that the CDSO-20 package fits the PCB layout constraints and thermal requirements of the design.

Part Context

This device belongs to the IDT54/74FCT374 family of octal D registers. It is functionally equivalent to FAST speed logic but offers improved performance. The FCT series is designed for high-speed CMOS applications, providing a balance between speed and power efficiency suitable for complex digital systems.

Replacement Considerations

Compatible substitutes include IDT54FCT374AD, IDT54FCT374ADB, and IDT54FCT374AE. These parts share similar functional descriptions as octal D registers with 3-state outputs. Verify package compatibility and temperature ranges when substituting.
