Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successors. Confirm the specific package type is 20-SSOP (0.154 inch width). Ensure the device meets the required operating temperature range and voltage specifications for your application. Check for RoHS compliance status if environmental regulations apply.

Selection Notes

Select this component when an octal bus transceiver with direction control is required for 5V logic systems. It is suitable for applications needing high-speed data transfer between buses. Consider the 20-SSOP package size for PCB layout constraints. Verify compatibility with existing logic families and voltage levels before integration.

Part Context

This part belongs to the FCT series of logic devices, known for fast CMOS technology. It serves as a bus transceiver, facilitating data flow between different system components. The CD74 prefix indicates it is part of the Texas Instruments/Harris logic product line, widely used in digital electronics for signal buffering and direction management.

Replacement Considerations

Compatible substitutes include other octal bus transceivers with similar pinouts and electrical characteristics, such as the 74FCT245 variants. Ensure the replacement supports 5V operation and has comparable propagation delays. Verify package compatibility, specifically the 20-SSOP form factor.
