SN74CBT3253PWR

Overview

The SN74CBT3253PWR is a 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 a low on-resistance of 8 Ohms maximum. The device supports high bandwidth up to 200 MHz with propagation delays of 6.7 ns (max) and isolation times of 6.1 ns (max). It is housed in a TVSOP-16 package, suitable for surface mount installation, and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual independent channels configured as 1-of-4 multiplexers or demultiplexers
• Low on-resistance for minimal signal attenuation
• High bandwidth capability for fast data transmission
• Low power consumption with microampere-level supply current

Applications

• Portable equipment requiring low-voltage operation
• Battery-powered systems
• Consumer electronics signal routing
• Industrial control signal switching

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TVSOP-16 package and tape-and-reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the 2.3V to 3.6V supply voltage range aligns with your system design constraints before procurement.

Selection Notes

Select this component when a dual 1-of-4 switching solution is required in a compact TVSOP-16 footprint. It is appropriate for designs needing low on-resistance and high bandwidth under single-supply conditions between 2.3V and 3.6V. Consider alternative packages if higher pin counts or different thermal performance are needed.

Part Context

This part belongs to the SN74CBT3253 series of analog switches. It is functionally similar to other devices in the family but distinguished by its specific TVSOP-16 packaging and voltage range. Related parts include variants with different package types or automotive qualifications, such as the SN74CB3Q3253 series.

Replacement Considerations

Direct replacements may include SN74CB3T3253DGVR (TVSOP-16) or SN74CBT3253DBR (SSOP-16), noting package differences. Verify electrical parameters and pin compatibility before substitution.
