SN74CBT3253CRGYR

Overview

The SN74CBT3253CRGYR is a dual 1-of-4 field-effect transistor (FET) multiplexer/demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 4 V to 5.5 V, with a typical operating voltage of 5 V. The device features two independent channels configured as 2 x 1:4 switches. Key electrical specifications include a maximum on-resistance of 12 Ohms, a maximum bandwidth of 200 MHz, and a maximum propagation delay of 6.7 ns. The component supports surface-mount installation in a VQFN-16 package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates two independent 1-of-4 FET switch channels for signal routing
• Provides low on-resistance characteristics suitable for high-speed data transmission
• Supports bidirectional signal flow between common and selectable ports

Applications

• High-speed data bus switching applications
• Signal path selection in consumer electronics

Procurement Notes

Verify the specific suffix CRGYR to confirm the VQFN-16 package type and reel packaging configuration. Ensure compatibility with the required 4 V to 5.5 V supply voltage range for your circuit design. Confirm moisture sensitivity level handling requirements during assembly, as indicated in the datasheet. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate authenticity and current production status before procurement.

Selection Notes

Select this component when a dual-channel multiplexer solution is required for 5 V logic systems. The VQFN-16 package offers a compact footprint for space-constrained designs. Consider the 12 Ohm on-resistance limit for signal integrity requirements. This device is appropriate for applications needing fast switching speeds up to 200 MHz bandwidth within the specified industrial temperature range.
