IDT74CBTLV3126QG8

Overview

The IDT74CBTLV3126QG8 is a single bus switch manufactured by Renesas Electronics Corporation, housed in a 16-SSOP surface-mount package. It functions as a 1 x 1:1 bidirectional switch with an on-resistance of 5Ω between ports A and B. The device supports low-voltage logic applications and provides isolation under power-off conditions. It is pin-out compatible with standard '126 logic products, facilitating direct replacement in existing designs without schematic modifications.

Feature Summary

• Provides bidirectional signal switching between two ports with low on-resistance
• Ensures high impedance isolation when the device is powered off
• Maintains pin compatibility with industry-standard '126 logic families

Applications

• Portable equipment requiring low voltage operation
• Consumer electronics utilizing low-power logic interfaces
• Computing products needing bus isolation capabilities

Procurement Notes

Verify component authenticity through authorized distributors or official Renesas channels. Confirm package integrity and marking consistency against the datasheet specifications. Check for obsolescence status as this part may be discontinued. Ensure storage conditions comply with moisture sensitivity levels to prevent damage prior to assembly.

Selection Notes

Select this component for designs requiring a single-channel bidirectional bus switch with low voltage compatibility. Consider the 16-SSOP package constraints for PCB layout. Evaluate the 5Ω resistance against signal integrity requirements. Verify that the application environment supports the specified operating conditions and isolation characteristics.

Part Context

This component belongs to the 74CBTLV series of low-voltage bus switches. It is part of Renesas' portfolio derived from Intersil technology. The series focuses on portable and consumer applications where power efficiency and small form factors are critical design parameters.

Replacement Considerations

Direct substitutes include other 74CBTLV3126 variants from Renesas or equivalent parts from other manufacturers that match the 16-SSOP package and '126 pinout. Ensure any replacement maintains the same bidirectional switching capability and power-off isolation features.
