SN74CBTLV3253DBQR

Overview

The SN74CBTLV3253DBQR is a low-voltage dual 1-of-4 FET multiplexer/demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V and features two independent channels, each configured as a 2 x 1:4 switch. The device utilizes an SSOP-16 surface-mount package and supports operation temperatures from -40°C to +85°C. Key electrical specifications include a maximum on-resistance of 40 ohms, a maximum propagation delay of 6.7 ns, and a maximum off-state leakage current of 10 uA.

Feature Summary

• Dual-channel architecture providing two independent 1-of-4 multiplexing paths
• Low-voltage operation optimized for 2.3 V to 3.6 V power supplies
• High-speed signal switching with minimal propagation delay
• Low power consumption suitable for battery-operated applications

Applications

• Portable consumer electronics requiring signal routing
• Automotive infotainment systems operating at 3.3 V
• Industrial control boards needing low-voltage switching

Procurement Notes

Verify the specific suffix 'DBQR' corresponds to the SSOP-16 package and tape-and-reel shipping configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the 2.3 V to 3.6 V operating range aligns with your system's power rails before finalizing procurement.

Selection Notes

Select this component when dual 1-of-4 switching is required in space-constrained designs using low-voltage logic. Compare against standard voltage variants if your system operates above 3.6 V. Consider the SSOP-16 footprint constraints and thermal dissipation capabilities relative to your PCB layout and ambient temperature conditions.
