FIFOs Memory Procurement Notes

Verify the specific suffix '20RJ' against the official Texas Instruments datasheet to confirm package type, temperature grade, and tape/reel specifications. Ensure the ordering part number matches the exact density and pinout requirements of your design. Cross-reference with authorized distributors to validate authenticity and traceability documentation before finalizing procurement.

FIFOs Memory Selection Notes

Select this component when a dual-port RAM solution is required for simultaneous read operations without bus contention. The 74ACT series offers superior speed compared to standard 74LS devices while maintaining 5 V logic compatibility. Consider the 256 x 8 bit capacity and 10 ns delay for applications demanding moderate data throughput with low power consumption during standby modes.

FIFOs Memory Part Context

This device is part of the broader 74ACT family of high-speed CMOS logic products from Texas Instruments. It serves as a specialized memory component within the logic IC category, distinct from standard gates or flip-flops. The SN74ACT7201LA variant provides dual-port functionality, differentiating it from single-port SRAMs like the SN74ACT373 latch. It complements other memory solutions such as the SN74ACT7814 FIFO for complex data handling tasks.

FIFOs Memory Replacement Considerations

Publicly confirmed substitute part numbers include SN74ACT7201L and IDT7201LA. Verify pin compatibility and electrical characteristics before substitution.
