SN74CBT3244CDGVR

Overview

The SN74CBT3244CDGVR is an octal FET bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and supports bidirectional data transmission across eight independent channels. The device utilizes a 20-pin TVSOP package and is rated for an operating temperature range from -40°C to +85°C. Designed for high-speed applications, it features low on-resistance and low power consumption characteristics suitable for digital bus switching.

Feature Summary

• Octal configuration providing eight independent bidirectional bus switches
• Low on-resistance for efficient signal transmission
• Compatible with standard TTL logic levels
• Supports single power supply operation

Applications

• High-speed data bus routing
• Portable equipment signal switching
• Consumer electronics bus management
• Industrial control system interconnects

Procurement Notes

Verify the complete part number including suffixes such as CDGVR against official Texas Instruments documentation to ensure correct package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference manufacturer datasheets for any recent product change notices or lifecycle status updates.

Selection Notes

Select this component when designing systems requiring multiple bidirectional data paths with low insertion loss. Ensure the design environment accommodates the specified 4.5V to 5.5V supply voltage range. Verify that the TVSOP-20 package dimensions fit the available PCB footprint and thermal constraints. Consider propagation delay specifications if timing margins are critical for the target application speed.

Part Context

This device belongs to the Texas Instruments SN74CBT series of bus switches. The series focuses on providing low resistance switching solutions for high-speed digital interfaces. The specific model integrates eight channels into a compact surface-mount package, distinguishing it from lower-channel-count variants in the same family.

Replacement Considerations

Check for direct pin-compatible alternatives within the SN74CBT series. Verify electrical parameters such as on-resistance and supply voltage compatibility before substituting. Consult official manufacturer substitution guides for validated equivalent parts.
