SN74CBT1G125DBV6

Overview

The SN74CBT1G125DBV6 is a single FET bus switch manufactured by Texas Instruments, designed for low-voltage applications. It operates within a supply voltage range of 2.3 V to 3.6 V and utilizes the CBT logic family technology. The component is housed in a compact SOT-23-5 surface-mount package, featuring five pins for efficient board space utilization. It provides one channel of signal switching capability with non-inverting functionality. The device supports powered-off protection to prevent current leakage when the power supply is off. It is rated for an operating temperature range from -40°C to +85°C, ensuring reliability in industrial environments.

Feature Summary

• Single-channel FET-based bus switch architecture
• Powered-off protection prevents input/output leakage
• Low on-resistance for efficient signal transmission
• Compact SOT-23-5 surface-mount packaging

Applications

• Portable battery-powered equipment
• Consumer electronics signal routing
• Industrial control systems
• Communications equipment

Procurement Notes

Verify the specific suffix '6' against official Texas Instruments documentation to confirm pinout compatibility and electrical characteristics. Ensure the ordering part number matches the exact datasheet revision required for your design. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Cross-reference the manufacturer's latest lifecycle status to ensure long-term availability.

Selection Notes

Select this component for designs requiring low-voltage operation between 2.3 V and 3.6 V. It is suitable for applications needing powered-off protection to isolate signals during power-down states. Consider the SOT-23-5 package size for space-constrained layouts. Compare propagation delay and on-resistance specifications against system timing requirements to ensure signal integrity.

Part Context

This device belongs to the SN74CBT1G125 series of single bus switches. It is part of Texas Instruments' portfolio of low-voltage analog switches designed for portable and consumer applications. The series offers various package options including SC70 and SOT-23 variants. It complements other logic families like LVC and AHCT by providing specialized switching functions rather than standard buffering.

Replacement Considerations

Check for SN74CBT1G125DBVR or SN74CBT1G125DCKR as potential equivalents. Verify that alternative parts match the 2.3 V to 3.6 V supply range and SOT-23-5 footprint. Ensure functional compatibility regarding powered-off protection and on-resistance values before substitution.
