TC7SPB9306TU,LF(CT

Overview

The TC7SPB9306TU is a CMOS 1-bit dual-supply bus switch designed for interfacing between nodes at different voltage levels. It supports VCCA ranges of 1.65 to 5.0 V and VCCB ranges of 2.3 to 5.5 V, enabling bidirectional level-shifting with external pull-up resistors. The device features an active-High Output Enable (OE) control signal and provides power-down protection at the OE input, which is 5.5 V tolerant. It operates within a temperature range of -40 °C to 85 °C and utilizes a UF6 package.

Feature Summary

• Dual-supply architecture supporting independent VCCA and VCCB power rails for flexible voltage translation
• Bidirectional data path capability allowing arbitrary power supply connections on A and B lines
• Active-High Output Enable control for switching isolation and connection management
• Power-down protection integrated at the OE input terminal

Applications

• Interfacing digital nodes operating at distinct voltage levels
• Bidirectional level-shifting in mixed-voltage system architectures
• Bus isolation via enable-controlled disconnection

Procurement Notes

Verify that the specific ordering suffix matches the required package configuration and environmental compliance status. Confirm that the OE pin polarity aligns with the active-High requirement specified for this model variant. Ensure design compatibility with the UF6 package dimensions and thermal characteristics during integration.

Selection Notes

Select this component when a single-channel bus switch with independent dual power supplies is required. The active-High enable logic distinguishes it from complementary variants. Verify that the target application requires bidirectional transfer without inherent directionality constraints imposed by internal circuitry.

Part Context

This device belongs to the TC7SPB series of low-voltage, low-power CMOS digital integrated circuits manufactured by Toshiba Semiconductor and Storage. The series focuses on providing efficient interfaces between disparate voltage domains using minimal footprint components suitable for portable and industrial electronics.

Replacement Considerations

The TC7SPB9307TU serves as a functional alternative within the same series, distinguished by its active-Low Output Enable logic rather than active-High.
