SN74CBT3253CDBR

Overview

The SN74CBT3253CDBR is a dual 1-of-4 FET multiplexer/demultiplexer switch IC manufactured by Texas Instruments. It operates within a supply voltage range of 4 V to 5.5 V and features two independent channels configured as 2 x 1:4 switches. 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 12 ohms, a maximum propagation delay of 6.7 ns, and a maximum transition time of 6.1 ns.

Feature Summary

• Dual-channel architecture providing two independent 1-to-4 multiplexing paths for signal routing applications.
• Low on-resistance characteristic ensures minimal signal attenuation across the switching path.
• High-speed switching capability with nanosecond-level propagation delays suitable for data-intensive interfaces.

Applications

• Portable equipment requiring low-power signal switching
• Consumer electronics utilizing high-speed data buses
• Industrial control systems needing reliable multiplexing

Procurement Notes

Verify the specific ordering suffix to confirm the SSOP-16 package type and tape-and-reel shipping configuration. Ensure compatibility with standard surface-mount assembly processes. Confirm RoHS compliance status and moisture sensitivity level requirements against your manufacturing standards before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel 1-to-4 multiplexer is required in a compact SSOP-16 footprint. It is appropriate for designs operating between 4 V and 5.5 V where low on-resistance and fast switching speeds are critical. Consider alternative packages like VQFN if board space constraints differ from SSOP dimensions.

Part Context

This part belongs to the SN74CBT3253C series of analog switches. It shares functional similarities with other devices in the family but differs in packaging and specific pinout configurations. The SN74CBT3253CDBR specifically denotes the SSOP-16 variant, distinguishing it from other package options available within the same logical function family.
