SN74CBTLV16212VR

Overview

The SN74CBTLV16212VR is a low-voltage 24-bit FET bus-exchange switch manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and supports an operating temperature range from -40 °C to +85 °C. The device integrates two independent 12-bit bus-exchange switches, each capable of handling bidirectional data flow. It utilizes a VQFN package with 48 exposed pads for thermal dissipation and signal integrity.

Feature Summary

• Integrates two independent 12-bit bus-exchange switches for flexible data routing
• Supports low-voltage operation down to 1.65 V for power efficiency
• Features bidirectional data flow capability across all channels

Applications

• Portable equipment requiring low-power signal switching
• Consumer electronics with limited voltage headroom
• Industrial control systems needing reliable bus exchange

Procurement Notes

Verify the specific suffix VR against official Texas Instruments documentation to confirm the exact tape-and-reel quantity and packaging configuration. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the 48-pin VQFN package dimensions match your PCB footprint design constraints before finalizing procurement.

Selection Notes

Select this component when designing circuits that require bidirectional bus exchange at low voltages between 1.65 V and 3.6 V. It is suitable for applications demanding high channel density in a compact form factor. Consider the thermal performance of the exposed pad if operating near maximum temperature limits. Ensure the input voltage levels are compatible with the system logic family to prevent signal integrity issues during switching operations.

Part Context

This device belongs to the SN74CBT series of low-voltage bus switches. It is designed to replace mechanical relays or discrete transistor switches in space-constrained designs. The CBTLV variant specifically targets applications requiring operation below 3.6 V, distinguishing it from standard 5 V tolerant counterparts. It provides a cost-effective solution for managing multiple data lines in portable and battery-operated devices.
