SN74CBTLV3253RGYR

Overview

The SN74CBTLV3253RGYR is a low-voltage FET multiplexer/demultiplexer switch IC manufactured by Texas Instruments. It features two independent channels, each configured as a 1-to-4 selector, housed in a 16-pin VQFN package. The device operates within a supply voltage range of 2.3 V to 3.6 V and supports a bandwidth of 200 MHz. Key electrical specifications include a maximum on-resistance of 40 Ohms, a maximum propagation delay of 6.7 ns, and a maximum off-time of 6.1 ns. It functions reliably across an operating temperature range from -40°C to +85°C with a maximum supply current of 10 uA.

Feature Summary

• Dual-channel architecture providing two independent 1-to-4 signal routing paths for flexible data selection.
• Low-voltage operation optimized for modern 2.5 V and 3.3 V system environments.
• High-speed switching capability supporting signal frequencies up to 200 MHz.
• Integrated Ioff protection ensures output ports remain in a high-impedance state when the device is powered down.

Applications

• Portable consumer electronics requiring efficient signal routing between multiple sources.
• Industrial control systems utilizing multi-channel data acquisition.
• Communication equipment performing signal channel expansion and switching.
• Server and storage devices managing I2C or SPI bus multiplexing.

Procurement Notes

Verify the specific suffix 'RGYR' corresponds to the 16-VQFN package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements during storage and handling. Ensure the selected component matches the required 2.3 V to 3.6 V supply voltage constraints for your target application design.

Selection Notes

Select this component when dual 1-to-4 multiplexing is required within a low-voltage 2.3 V to 3.6 V operational window. The VQFN-16 package is suitable for space-constrained surface-mount designs. Consider alternative packages like SSOP if manual assembly is necessary, or verify if higher voltage tolerance is needed for 5 V systems.

Part Context

This part belongs to the SN74CBTLV3253 series of low-voltage analog switches. It serves as a compact solution for signal routing in portable and industrial applications. The device complements other logic families by offering high-speed performance in a small form factor, addressing the need for efficient data path management in dense circuit boards.

Replacement Considerations

SN74CBT3253DBR: Offers identical functionality but utilizes a 16-SSOP package instead of VQFN, suitable for different board layouts.

FAQ

What is the maximum operating frequency supported by this multiplexer?

The device supports a bandwidth of up to 200 MHz, making it suitable for high-speed signal switching applications.

How does the device behave when powered off?

It features Ioff protection, which forces the output ports into a high-impedance state to prevent damaging back-powering currents when the supply voltage is removed.
