SN74CBT3245CDGVR

Overview

The SN74CBT3245CDGVR is an octal FET bus switch manufactured by Texas Instruments. It features a single 8-bit bidirectional data path with three-state outputs, housed in a 20-pin TVSOP package. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports low-power CMOS technology. Key electrical characteristics include a maximum on-resistance of 12 ohms and a propagation delay of 150 ps. It functions across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides an octal (8-bit) bidirectional bus switching configuration for high-speed data routing.
• Integrates three-state outputs to facilitate direct connection to system buses without external termination.
• Supports level shifting between different voltage domains while maintaining signal integrity.

Applications

• High-speed data routing in portable consumer electronics
• Level translation between 3.3-V and 5-V memory systems
• Bus driver applications requiring low power consumption

Procurement Notes

Verify the specific suffix 'DGVR' corresponds to the TVSOP-20 package and reel packaging format. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the operating voltage range aligns with your system's 3.3-V supply rails before finalizing procurement.

Selection Notes

Select this component when an octal bus switch with low on-resistance and fast switching speeds is required. It is suitable for designs needing bidirectional data flow control between different voltage domains. Consider the TVSOP package size constraints and thermal performance relative to other available packages like SSOP or TSSOP.

Part Context
