SN74CBT16209ADGVR

Overview

The SN74CBT16209ADGVR is an 18-bit high-speed TTL-compatible bus switch or exchanging device manufactured by Texas Instruments. It operates within a supply voltage range of 1.65V to 3.6V and features a 48-pin TVSOP package. The device provides low on-resistance for efficient signal transmission and includes overvoltage protection capabilities. It supports bidirectional data flow and is designed for applications requiring high-density bus switching with minimal power consumption.

Feature Summary

• Provides 18 bits of high-speed bus switching or exchanging functionality
• Features TTL-compatible input levels for broad logic interface compatibility
• Includes overvoltage protection to safeguard against input signals exceeding the supply voltage

Applications

• High-density data bus switching in portable electronics
• Signal exchanging between different voltage domains
• Bus holding and driving in consumer devices

Procurement Notes

Verify the specific suffix 'DGVR' confirms the tape and reel packaging format required for automated assembly processes. Ensure the 'A' designation aligns with the intended temperature grade and performance specifications for the target application environment. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when an 18-bit wide bus switch is required with TTL-compatible inputs. It is suitable for designs needing bidirectional data transfer with overvoltage tolerance. Consider the 48-TVSOP package constraints for PCB layout. Evaluate the 1.65V to 3.6V operating range against system power rails to ensure compatibility with both 1.8V and 3.3V logic families.

Part Context

This part belongs to the SN74CBT16209 family of FET bus-exchange switches. It is functionally similar to the SN74CBT16209 but specified in the DGVR package variant. The device complements other bus switching solutions by offering high channel density in a compact surface-mount footprint, addressing space-constrained design requirements in modern electronic systems.

Replacement Considerations

Check for SN74CBT16209ADGVT as a potential alternative if TSSOP packaging is preferred over TVSOP. Verify pin-to-pin compatibility and electrical parameters against the original specification sheet before substitution.
