SN74CBTLV3253DG4

Overview

The SN74CBTLV3253DG4 is a dual 1-of-4 multiplexer/demultiplexer switch IC from the Texas Instruments SN74CBTLV3253 series. It operates within a supply voltage range of 2.3 V to 3.6 V and features a maximum on-resistance of 40 Ohms. The device supports a bandwidth of 200 MHz with a maximum propagation delay of 6.7 ns and a maximum leakage current of 10 uA. It is housed in a VQFN-16 package, suitable for surface mount installation, and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing two independent 1-of-4 multiplexing paths
• Low power consumption with minimal static current draw during operation
• High-speed signal switching capability supporting wide bandwidth applications

Applications

• Portable consumer electronics requiring low-voltage signal routing
• Battery-powered devices utilizing efficient power management switches
• Data acquisition systems needing high-density signal selection

Procurement Notes

Verify the specific suffix 'DG4' against official manufacturer documentation to confirm pinout compatibility and RoHS status. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the datasheet revision history for any recent design changes or material updates that may affect integration.

Selection Notes

Select this component when a dual 1-of-4 configuration is required within a compact VQFN-16 footprint. It is appropriate for designs operating strictly between 2.3 V and 3.6 V where low on-resistance and high bandwidth are critical. Consider thermal dissipation requirements given the small package size and intended surface mount application environment.
