SN74CBT16210DGGR

Overview

The SN74CBT16210DGGR is a digital bus switch IC manufactured by Texas Instruments, featuring 20-bit FET bus switching capability. It operates within a supply voltage range of 2.3 V to 3.6 V and supports a maximum operating temperature of +85 C with a minimum of -40 C. The device exhibits a maximum on-resistance of 9.5 Ohms and a maximum propagation delay of 250 ps. It is housed in a TSSOP-48 package suitable for surface mount installation.

Feature Summary

• Provides 20-bit bidirectional data path switching for high-density bus applications
• Enables low on-resistance signal transmission for minimal signal degradation
• Supports fast switching speeds with low propagation delay characteristics

Applications

• High-speed data bus isolation in portable electronic devices
• Level shifting between different voltage domains in system interconnects
• Bus driver replacement in memory and storage subsystems

Procurement Notes

Verify the specific ordering suffix DGGR corresponds to the TSSOP-48 package and reel packaging configuration required for your assembly process. Confirm that the 2.3 V to 3.6 V operating voltage range aligns with your system power rails. Ensure compatibility with RoHS standards if mandated by your regional regulations or customer specifications before finalizing procurement.

Selection Notes

Select this component when a 20-bit wide bus switch is required within a single package to save board space. It is appropriate for designs needing operation below 3.6 V where low on-resistance is critical for signal integrity. Consider the TSSOP-48 footprint constraints and thermal requirements during the layout phase to ensure reliable performance across the specified temperature range.
