Flip Flops Procurement Notes

Verify the specific suffix 'DGGR' corresponds to the tape-and-reel packaging configuration when ordering. Confirm that the required supply voltage aligns with the 1.65 V to 3.6 V operational window. Ensure thermal management strategies account for the specified -40 °C to +85 °C operating range. Cross-reference the pinout diagram with the target PCB layout to guarantee correct orientation and connection of the 56-terminal TSSOP package.

Flip Flops Selection Notes

Select this component when a 20-bit width is necessary for system architecture. Consider the ALVCH series characteristics for compatibility with existing 3.3 V or lower voltage domains. Evaluate the propagation delay specifications against the system's timing constraints to ensure signal integrity. Compare alternative packages if space constraints differ from the standard TSSOP-56 footprint.

Flip Flops Part Context

This part belongs to the SN74ALVCH16xx family of universal bus drivers, which are optimized for low-voltage CMOS technology. The family provides scalable solutions for various bit-widths, ranging from smaller configurations to larger 20-bit implementations like this model. These devices are integral to modern digital designs requiring efficient data routing between components operating at reduced voltage levels.

Flip Flops Replacement Considerations

Check for variants with different suffixes indicating alternative packaging options, such as tube versus reel formats. Verify functional equivalence with other members of the SN74ALVCH16xx series if pin-out compatibility is required. Ensure any substitute maintains the same voltage and temperature specifications.
