Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current product status documentation to confirm availability and compliance with latest environmental standards. Ensure the ordering part number matches the exact package and temperature grade requirements for your design. Cross-reference the datasheet revision history for any updates to electrical characteristics or mechanical outlines before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring 16-bit wide data paths at 2.5-V or 3.3-V supply voltages. The high-bandwidth characteristic makes it suitable for applications demanding fast signal transitions. Confirm that the 48-TSSOP package fits the PCB layout constraints and that the -40°C to +85°C operating range meets the environmental conditions of the target application.

Part Context

This device belongs to the Texas Instruments SN74CB3Q family of bus switches. It shares functional similarities with other 16-bit switches like the SN74CBT16244 but is optimized for lower voltage operation. The DGGR suffix indicates the specific tape-and-reel packaging format and temperature range, distinguishing it from other variants in the same logical family.
