TC7SPB9306TU,LF

Overview

The TC7SPB9306TU,LF is a CMOS 1-bit dual-supply bus switch designed for interfacing between nodes at different voltage levels. It supports VCCA from 1.65 V to 5.0 V and VCCB from 2.3 V to 5.5 V. The device features bidirectional level-shifting capabilities with an ON-resistance of 5.0 Ω (typical) at specific test conditions. It operates within a temperature range of -40°C to 85°C and utilizes the UF6 package.

Feature Summary

• Provides bidirectional interface between two nodes operating at different voltage levels using independent power supplies.
• Features low ON-resistance for efficient signal transmission across the bus switch channels.
• Includes power-down protection at the Output Enable input, ensuring tolerance up to 5.5 V.
• Supports bidirectional level-shifting functionality through the addition of external pull-up resistors.

Applications

• Interfacing digital circuits operating at distinct voltage domains such as 1.8 V, 2.5 V, 3.3 V, and 5.0 V.
• Bidirectional level-shifting in data lines where voltage translation is required without restriction on relative magnitude.
• System designs requiring isolation of buses via the enable signal when the switch is disabled.

Procurement Notes

Verify that the ordering suffix LF corresponds to the RoHS-compliant version specified by Toshiba Semiconductor and Storage. Confirm the UF6 package type matches the design footprint requirements. Ensure the active-high OE logic aligns with the control circuitry, distinguishing it from the active-low variant.

Selection Notes

Select this component when a single-channel bus switch with dual-supply capability is needed for voltage translation. The device is suitable for applications requiring low ON-resistance and robust power-down protection. Consider the UF6 package constraints and the specific VCCA/VCCB voltage combinations supported by the operating ranges.

Part Context

This part belongs to the TC7SPB series of CMOS digital integrated circuits manufactured by Toshiba Semiconductor and Storage. It is functionally related to the TC7SPB9307TU, which shares similar electrical characteristics but differs in the polarity of the Output Enable signal. Both devices serve as low-voltage, low-power solutions for dual-supply bus switching applications.

Replacement Considerations

The TC7SPB9307TU is a direct functional substitute within the same family, differing only in that its Output Enable is active-Low rather than active-High. Verify logic compatibility before substitution. No other cross-model replacements are confirmed in the provided documentation.
