Overview
The SN74CBTLV3126DGVR is a low-voltage quadruple FET bus switch manufactured by Texas Instruments. It operates on a single power supply ranging from 2.3 V to 3.6 V and features four independent 1:1 bidirectional switches. The device supports powered-off protection, ensuring no current flows when the chip is unpowered. It is housed in a 14-TVSOP package with a width of 4.40 mm. The component functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Provides four independent bidirectional bus switches for signal routing
- Supports powered-off protection to prevent leakage currents
- Compatible with SPI and JTAG signal protocols
Applications
- Portable equipment requiring low voltage operation
- SPI interface signal switching
- JTAG boundary scan circuitry
Procurement Notes
Verify the specific suffix DGVR indicates the TVSOP-14 tape and reel packaging configuration. Confirm RoHS3 compliance status as documented in the manufacturer's environmental classification. Ensure the ordering part number matches the exact functional specification for the 74CBTLV series before procurement.
Selection Notes
Select this component for applications requiring low on-resistance and high bandwidth in compact surface-mount designs. Compare against the SN74CBTLV3125 if inverting functionality is required instead of non-inverting. Consider the TVSOP package dimensions for PCB layout constraints relative to other available packages like TSSOP or SOIC.
Part Context
This device belongs to the Texas Instruments 74CBTLV logic family, designed for low-voltage digital signal switching. It serves as a bus switch solution for managing data lines in portable systems. The DGVR suffix specifically denotes the 14-pin Thin Visual Small Outline Package variant distributed in tape and reel format for automated assembly.
Replacement Considerations
The SN74CBTLV3126PWR is a pin-compatible alternative offering the same electrical characteristics in a 14-TSSOP package. Verify package footprint differences between TVSOP and TSSOP during board redesign.
