SN74CB3Q3251DGVR

Overview

The SN74CB3Q3251DGVR is a low-voltage 1-of-8 FET multiplexer/demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V and features an 8-channel configuration in a 16-pin TVSOP package. Key electrical parameters include a maximum on-resistance of 11 Ohms, a bandwidth of 200 MHz, and propagation delays of 6.7 ns (typical) and 6.1 ns (maximum). The device supports an operating temperature range from -40°C to +85°C and draws a maximum supply current of 10 µA.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for enhanced reliability in vehicle applications.
• Low on-resistance design minimizes signal attenuation and power loss during data transmission.
• High-speed switching capability ensures minimal propagation delay for efficient signal routing.
• Wide operating voltage range supports integration into various low-power digital systems.

Applications

• Automotive infotainment system signal routing
• Portable electronic device data bus switching
• Industrial control system multiplexing

Procurement Notes

Verify the specific suffix DGVR corresponds to the TVSOP-16 package and reel packaging format required for your assembly process. Confirm that the component meets AEC-Q100 automotive grade requirements if intended for vehicle electronics. Ensure the 2.3V to 3.6V supply voltage aligns with your system's power rails. Check for RoHS compliance documentation prior to final procurement approval.

Selection Notes

Select this component when automotive reliability is required alongside low-voltage operation. The TVSOP-16 package offers a compact footprint suitable for space-constrained designs. Compare the 11 Ohm on-resistance against other series members if lower resistance is critical for high-current applications. Consider the 200 MHz bandwidth for high-frequency signal integrity needs.

Part Context

This part belongs to the SN74CB3Q3251 family of low-voltage FET multiplexers designed for automotive and industrial markets. It shares functional similarities with the SN74CBTLV3251 series but includes additional automotive qualification features. The device serves as a direct replacement for standard logic switches where higher reliability and wider temperature tolerance are necessary.

Replacement Considerations

The SN74CBTLV3251DR is a non-automotive equivalent with similar electrical characteristics but lacks AEC-Q100 certification. Verify package compatibility between TVSOP-16 and SOIC-Narrow-16 if substituting. Ensure voltage and speed specifications meet application requirements when cross-referencing with the SN74CB3Q3251PWR variant.
