SN74CBT3126DGVR

Overview

The SN74CBT3126DGVR is a low-voltage quadruple FET bus switch manufactured by Texas Instruments. It operates on a single power supply ranging from 2.3V to 3.6V and features four independent switches in a 14-TVSOP package. The device supports powered-off protection, allowing I/O lines to remain high-impedance when VCC is off. It is designed for applications requiring SPI and JTAG signal support with low on-resistance characteristics.

Feature Summary

• Provides powered-off protection to maintain high-impedance states during power loss
• Supports standard digital communication protocols including SPI and JTAG signals
• Features low on-resistance for efficient signal transmission across the bus

Applications

• SPI flash memory expansion circuits
• JTAG boundary scan interface connections
• Low-voltage data bus switching systems

Procurement Notes

Verify the specific suffix 'DGVR' corresponds to the 14-TVSOP package and tape-and-reel quantity. Confirm RoHS3 compliance status as per the latest manufacturer documentation. Ensure the operating voltage range of 2.3V to 3.6V matches the target system design requirements before procurement.

Selection Notes

Select this component for designs requiring low-voltage operation between 2.3V and 3.6V. The 14-TVSOP package is suitable for surface-mount assembly with space constraints. Consider the powered-off protection feature if the system requires safe isolation during power-down sequences or hot-swap scenarios.

Part Context

This part belongs to the SN74CBTLV3126 family of low-voltage quadruple FET bus switches. The 'DGVR' suffix indicates the TVSOP-14 package type and reel packaging configuration. It serves as a direct functional equivalent to other variants within the same logic family that share identical electrical specifications but differ in package style.

Replacement Considerations

SN74CBTLV3126DGVR is the base part number without packaging suffix variations. SN74CBTLV3126PWR offers the same functionality in a TSSOP-14 package.
