TC7WPB9306,9307FC/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7WPB9306FC,TC7WPB9307FC TC7WPB9306FK,TC7WPB9307FK Low Voltage/Low Power 2-Bit Dual Supply Bus Switch The TC7WPB9306 and TC7WPB9307 are CMOS 2-bit dual-supply bus switches that can provide an interface between two nodes at different voltage levels. These devices 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 enable signal can be used to disable the device so that the buses are effectively isolated. The Output Enable ( OE :TC7WPB9307, OE:TC7WPB9306) input is common for all the two-bits of the data lines; thus these device are used as a single two-bits bus switch. For the TC7WPB9306, Output Enable (OE) is active-High: When OE is High, the switch is on; when Low, the switch is off. For the TC7WPB9307, Output Enable ( OE ) is active-Low: When OE is Low, the switch is on; when High, the switch is off. The TC7WPB9306 and TC7WP9307 supports power-down protection at the OE ,OE input, with OE ,OE being 5.5-V tolerant. The channels consist of n-type MOSFETs. All the inputs provide protection against electrostatic discharge. TC7WPB9306FC,TC7WPB9307FC TC7WPB9306FK,TC7WPB9307FK Weight CSON8-P-0.4 SSOP8-P-0.50A : 0.002 g (typ.) : 0.01 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).
