TC7MPB9307FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MPB9307FT/FK Low Voltage/Low Power 8-Bit Dual Supply Bus Switch The TC7MPB9307 is a CMOS 8-bit dual-supply bus switch that can provide an interface between two nodes at different voltage levels. The TC7MPB9307 can be connected to two independent power supplies. VCCA supports 1.8-V, 2.5-V and 3.3-V power supplies, whereas VCCB supports 2.5-V, 3.3-V and 5.0V power supplies. Bidirectional level-shifting is possible by simply adding external pull-up resistors between the An/Bn data lines and the VCCA/VCCB supplies. There is no restriction on the relative magnitude of the An and Bn voltages; both the An and Bn data lines can be pulled up to arbitrary power supplies. The Output Enable ( OE ) input controls the connection or isolation of two bus systems on the VCCA and VCCB sides. The OE input is common for all the eight bits of the data lines; thus the TC7MPB9307 is used as a single eight-bit bus switch. When OE is Low, the switch is on, and An is connected to Bn. When OE is High, the switch is open. The TC7MPB9307 supports power-down protection at the OE input, with OE being 5.5-V tolerant. The channels consist of n-type MOSFETs. All the inputs provide protection against electrostatic discharge. TC7MPB9307FT TC7MPB9307FK Weight TSSOP20-P-0044-0.65A VSSOP20-P-0030-0.50 : 0.08 g (typ.) : 0.03 g (typ.)

Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
