Flip Flops Procurement Notes

Verify the specific suffix 'DLR' corresponds to the tape and reel packaging format when ordering. Confirm that the 56-SSOP footprint matches the target PCB design constraints. Ensure the operating environment remains within the specified temperature range of -40°C to +85°C for optimal performance and longevity of the component.

Flip Flops Selection Notes

Select this component when an 18-bit wide bus interface is required with three-state output isolation. It is appropriate for designs operating at 2.5 V or 3.3 V where high-speed data transfer rates near 150 MHz are necessary. Consider the 56-SSOP package size for space-constrained surface-mount applications requiring robust drive strength.

Flip Flops Part Context

This part belongs to the ALVTH series of advanced low-voltage CMOS logic devices from Texas Instruments. These components are designed for high-density memory and bus-oriented applications. The 16821 variant specifically provides latching functionality for 18-bit data paths, distinguishing it from simple buffers or transceivers in the same family.
