Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type and tape-and-reel quantity against the manufacturer's official datasheet for the CY74FCT/74FCT prefix variants. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering suffix matches the required lead time and packaging format.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring 16-bit wide data paths with low propagation delay. The FCT series offers speed comparable to LS-TTL but with CMOS power consumption. Verify that the system voltage aligns with the 4.75V to 5.25V operating range and that TTL input thresholds are compatible with the driving logic sources.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments FCT (Fast CMOS Technology) family, which bridges the performance gap between standard CMOS and bipolar TTL logic. The 74FCT245 architecture is widely used for octal or hex configurations, while this specific variant expands the width to 16 bits. It is designed for high-density PCB layouts requiring fast switching speeds.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-to-pin replacements may include other 16-bit FCT bus transceivers from Texas Instruments or Renesas. Verify that substitute parts maintain the same 48-pin TSSOP package and identical electrical characteristics, specifically the 4.75V-5.25V supply range and non-inverting output polarity.
