Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ZATQ' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the procurement source provides valid RoHS compliance documentation as required for modern electronic assemblies. Cross-reference the package type and lead finish with your PCB footprint requirements before finalizing orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal bidirectional interface with TTL compatibility is required. The 74FCT series offers faster switching speeds compared to standard 74LS logic while maintaining compatible voltage levels. Consider the 20-pin TSSOP package constraints and the 5V operating voltage requirement during circuit design. Verify that the 64mA sink current meets the load requirements of the connected bus lines.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the IDT 74FCT series of fast CMOS logic devices. These components are designed to bridge the speed gap between older TTL logic and newer CMOS technologies. The 74FCT245 variant specifically provides octal bus driving capabilities, making it a standard choice for system interconnects where data direction must be controlled dynamically by a single signal.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include the CY74FCT245TSOC from Texas Instruments and the IDT74FCT245TQ. Verify that alternative parts match the 20-pin TSSOP package dimensions and maintain identical electrical characteristics, such as the 7 ns propagation delay and 5V supply range.
