Shift Registers Procurement Notes

Verify the manufacturer source carefully as the provided documentation lists YAGEO as the manufacturer for this specific part number variant. Confirm RoHS compliance status and ensure the datasheet matches the exact suffix requirements for your assembly process. Cross-reference the pinout and electrical specifications against the official Texas Instruments or authorized distributor documentation to avoid integration errors due to potential vendor discrepancies.

Shift Registers Selection Notes

Select this component when a 10-bit serial-to-parallel conversion is required with high-speed performance. The ACT series offers faster switching speeds compared to standard 74LS counterparts while maintaining CMOS power efficiency. Ensure the design accommodates the 20-pin SOIC footprint and that the operating voltage remains strictly within the 4.5 V to 5.5 V window for optimal timing characteristics.

Shift Registers Part Context

This device belongs to the 74ACT logic family, which utilizes EPIC (Enhanced-Performance Implanted CMOS) technology. It is designed to replace older 74LS devices in high-speed applications. The 74ACT11898 specifically addresses needs for moderate-width data path serialization, offering a balance between pin count and data throughput for embedded systems.

Shift Registers Replacement Considerations

Check for direct equivalents such as the SN74ACT11898. Verify if alternative manufacturers offer compatible pinouts and electrical parameters. Ensure any substitute maintains the same 10-bit depth and right-shift direction to prevent firmware or hardware redesign.
