SN74CBT3253DBQRG4

Overview

The SN74CBT3253DBQRG4 is a dual 1-of-4 FET multiplexer/demultiplexer from Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V. The device features a maximum on-resistance of 40 Ohms, ensuring low signal attenuation. Propagation delays are specified with a maximum of 6.7 ns for turn-on time and 6.1 ns for turn-off time. It supports a bandwidth of 200 MHz and draws a maximum quiescent current of 10 uA. The component is housed in a 16-pin SSOP package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual independent channels providing flexible routing between four inputs and one output or vice versa.
• Low on-resistance design minimizes signal distortion and power loss during transmission.
• High-speed switching capability supports data rates requiring fast transition times.
• Ultra-low static power consumption suitable for battery-operated and energy-efficient systems.

Applications

• Portable equipment requiring efficient signal path management
• Consumer electronics utilizing low-voltage logic interfaces
• Industrial control systems needing reliable data routing
• Telecommunications infrastructure components

Procurement Notes

Verify the specific suffix 'RG4' indicates RoHS compliance and green material status as per manufacturer standards. Confirm the package type matches the required PCB footprint. Ensure the operating voltage requirements align with the system's power supply rails. Check for moisture sensitivity level constraints during storage and handling procedures.

Selection Notes

Select this component when a dual-channel multiplexer is required for low-voltage applications. Compare propagation delay specifications against system timing requirements. Evaluate the on-resistance impact on signal integrity for high-frequency operations. Consider the package size relative to available board space constraints.

Part Context

This part belongs to the SN74CBTLV3253 series of low-voltage FET multiplexers. It shares functional similarities with other devices in the family but differs in packaging and specific electrical characteristics. The 'DBQR' designation refers to the tape-and-reel SSOP package variant. The 'G4' suffix typically denotes environmental compliance attributes defined by the manufacturer.

Replacement Considerations

SN74CBTLV3253DBQ is a pin-compatible alternative within the same series. SN74CBTLV3253DBQR offers identical functionality in a reel-packaged format. Verify that substitute parts meet the same voltage and speed requirements before implementation.
