FIFOs Memory Procurement Notes

Verify the specific suffix '40DL' against the manufacturer's official datasheet to confirm pinout compatibility and electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for obsolescence notices or lifecycle changes directly from Texas Instruments before finalizing procurement plans.

FIFOs Memory Selection Notes

Select this component when an 18-bit wide synchronous FIFO interface is required at moderate speeds up to 25 MHz. Ensure the system operating voltage aligns with the 3 V to 3.6 V specification. Consider the 56-pin SSOP package constraints for PCB layout. Verify that the 20 ns access time meets the timing requirements of the target application.

FIFOs Memory Part Context

This part belongs to the SN74ALVC7805 family of synchronous FIFOs. The ALVC series offers advanced low-voltage CMOS performance. The 7805 variant specifically provides 18-bit width configurations.
