TC7SPB9307TU,LF

Overview

The TC7SPB9307TU,LF is a CMOS 1-bit dual-supply bus switch designed for bidirectional level-shifting between nodes operating at different voltage levels. It features an active-Low Output Enable (OE) control signal and supports independent power supplies VCCA (1.65V to 5.0V) and VCCB (2.3V to 5.5V). The device provides 5.5V tolerance and power-down protection at the OE input. It utilizes n-type MOSFET channels with a typical ON-resistance of 5.0Ω and operates within a temperature range of -40°C to 85°C in a UF6 package.

Feature Summary

• Bidirectional level-shifting capability between two independent power supply domains without restrictions on relative voltage magnitudes.
• Active-Low Output Enable (OE) control allows effective isolation of buses when disabled.
• 5.5V tolerance and power-down protection integrated at the OE input pin.
• Low ON-resistance characteristic ensuring minimal signal degradation during conduction.

Applications

• Interface connections between logic nodes operating at different voltage levels
• Bidirectional data translation in mixed-voltage systems
• Bus isolation applications requiring controlled enable/disable states

Procurement Notes

Verify the specific ordering suffix corresponds to the LF designation for lead-free compliance. Confirm the UF6 package type matches the target footprint requirements. Ensure the design accounts for the active-Low OE functionality distinct from the TC7SPB9306TU variant. Validate that the application voltage ranges fall within the specified VCCA and VCCB operational limits defined in the datasheet.

Selection Notes

Select this component when a single-channel bidirectional switch with active-Low enable control is required. It is suitable for interfacing low-voltage logic with higher-voltage domains up to 5.5V. Consider the UF6 package constraints for board space. Compare against the TC7SPB9306TU if an active-High enable signal is preferred instead.

Part Context

This part belongs to the TC7SPB series of low-voltage, low-power CMOS digital integrated circuits manufactured by Toshiba Semiconductor and Storage. It is functionally paired with the TC7SPB9306TU, differing primarily in the polarity of the Output Enable control signal. Both devices share similar electrical characteristics and packaging options for dual-supply bus switching applications.

Replacement Considerations

The TC7SPB9306TU serves as a functional alternative but requires inversion of the enable signal logic due to its active-High OE configuration. No other direct substitutes are confirmed in the provided documentation.
