SN74CB3Q6800PW

Overview

The SN74CB3Q6800PW is a 10-bit FET bus switch manufactured by Texas Instruments, designed for low-voltage digital signal routing. It operates within a supply voltage range of 2.5 V to 3.3 V and features precharged outputs to minimize inrush current during switching events. The device is housed in a TSSOP-24 package and supports surface-mount installation. It provides high-bandwidth performance suitable for data-intensive applications while maintaining low power consumption characteristics typical of the SN74CB3Q series.

Feature Summary

• Features precharged outputs to reduce switching noise and inrush current
• Supports low-voltage operation from 2.5 V to 3.3 V
• Provides 10-bit bidirectional data path configuration

Applications

• Portable equipment requiring low-power signal switching
• Consumer electronics with limited voltage rails
• Industrial control systems utilizing low-voltage logic

Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-24 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the component meets automotive qualification requirements if intended for AEC-Q100 certified designs, as standard commercial grades may differ from qualified variants.

Selection Notes

Select this component for designs requiring 10-channel isolation in compact surface-mount footprints. Compare against other SN74CB3Q family members for pin compatibility and voltage level matching. Verify that the 2.5 V to 3.3 V operating range aligns with the system's power delivery network. Consider thermal dissipation capabilities within the TSSOP-24 enclosure for high-density PCB layouts.

Part Context

This part belongs to the SN74CB3Q series, which focuses on automotive-grade reliability and low-voltage performance. The CBTK designation indicates a specific FET-based architecture optimized for bandwidth and low on-resistance. It serves as a bridge between standard logic families and modern low-power embedded systems.

Replacement Considerations

SN74CB3Q6800PWG4: Lead-free variant with identical electrical specifications. SN74CB3Q6800PWRE4: Alternative lead-free packaging option. Verify package dimensions and pinout compatibility before substitution.
