SN74CBTK32245GKER

Overview

The SN74CBTK32245GKER is an octal bus switch IC from Texas Instruments, featuring a 96-LFBGA package. It provides 8-bit bidirectional data switching with a single control input. The device operates on a single supply voltage and supports high-speed signal transmission. Key electrical characteristics include low on-state resistance and TTL-compatible logic levels, ensuring reliable performance in digital systems requiring efficient bus management.

Feature Summary

• Provides eight independent bidirectional bus switches for data routing
• Features low on-state resistance to minimize signal loss
• Supports TTL-compatible logic levels for broad compatibility
• Operates with a single power supply configuration

Applications

• High-speed data bus switching in computing systems
• Signal routing in consumer electronics devices
• Interface bridging between different voltage domains
• Portable equipment requiring compact packaging solutions

Procurement Notes

Verify the specific suffix GKER against official Texas Instruments documentation to confirm pinout and package dimensions. Ensure the component meets RoHS compliance requirements for your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the 96-LFBGA package is compatible with your PCB assembly capabilities.

Selection Notes

Select this component when an octal bus switch with a compact BGA footprint is required. Consider the low on-resistance for maintaining signal integrity in high-frequency applications. Evaluate the single-supply operation against system power constraints. Compare the LFBGA package size against available board space and thermal dissipation needs.

Part Context

This part belongs to the SN74CBT series of high-performance analog switches from Texas Instruments. The CBTK variant specifically denotes advanced packaging options like the LFBGA. These devices are designed for portable applications where space and power efficiency are critical. The series offers improved speed and lower power consumption compared to standard logic families.

Replacement Considerations

Check for SN74CBT32245 variants with different package suffixes if the LFBGA form factor is not suitable. Verify functional equivalence with other octal bus switches from the same family. Ensure any substitute maintains the same voltage range and control logic compatibility.
