SN74CBT3126PWRG4

Overview

The SN74CBT3126PWRG4 is a low-voltage quadruple FET bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V and features four independent channels in a 14-TSSOP package. The device supports powered-off protection, ensuring that high-impedance states are maintained when power is removed. It is designed for applications requiring signal switching with low on-resistance and minimal propagation delay.

Feature Summary

• Provides four independent single-pole single-throw (SPST) switches
• Supports powered-off protection to prevent current leakage
• Operates with low supply voltage ranges suitable for modern digital systems

Applications

• Portable equipment requiring low power consumption
• Consumer electronics utilizing low-voltage logic interfaces
• Computing products needing efficient signal routing

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current datasheet to confirm compliance with RoHS directives and lead-free status. Ensure the ordering part number matches the exact package type and temperature grade required for your design. Cross-reference with official Texas Instruments documentation to validate availability and lifecycle status before finalizing procurement plans.

Selection Notes

Select this component when designing circuits that require multiple bidirectional data paths controlled by a single enable signal. The low on-resistance makes it suitable for maintaining signal integrity across various loads. Consider the 14-TSSOP package dimensions for PCB layout constraints and ensure the operating voltage aligns with the system's power supply rails.

Part Context

This device belongs to the SN74CBT series of low-voltage bus switches. It is functionally similar to other members like the SN74CBTLV3126 but may differ in specific electrical characteristics or packaging options. The series is designed for high-speed data transmission in portable and consumer applications where space and power efficiency are critical.

Replacement Considerations

Check for direct pin-to-pin replacements such as the SN74CBT3126PW or SN74CBT3126PWR if the 'G4' suffix indicates a specific environmental compliance variant. Verify that any substitute maintains the same voltage range and package footprint to ensure compatibility without redesigning the circuit board.
