TC7MPB9326FT,TC7MPB9327FT CMOS Digital Integrated Circuits Silicon Monolithic TC7MPB9326FT,TC7MPB9327FT 1. Functional Description • Low-Voltage, Low-Power Dual SPDT Supply Bus Switch 2. General The TC7MPB9326FT and TC7MPB9327FT are CMOS dual multiplexer/demultiplexer 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 5.0 V power supplies. Bidirectional level-shifting is possible by simply adding external pull-up resistors between the A/Bn data lines and the VCCA / VCCB supplies. There is no restriction on the relative magnitude of the A and Bn voltages; both the 1A/2A and 1B1/1B2 ,2B1/2B2 data lines can be pulled up to the arbitrary power supplies. The Output Enable pin (OE) can be used to disable the device so that the bus lines are effectively isolated. This device consists of dual individual two-inputs multiplexer/demultiplexer with a common select input (S) and an output enable (OE:TC7MPB9326FT, OE:TC7MPB9327FT). The 1A/2A inputs are connected to 1B1/1B2 and 2B1/2B2 outputs based on the combination of select input and output enable. For TC7MPB9326FT, it has an active high Output Enable (OE) : When OE is High, the switch is on; When Low, the switch is turned off. For the TC7MPB9327FT, it has an active low Output Enable (OE) : When OE is Low, the switch is turned on; When OE is High, the switch is off. The TC7MPB9326FT and TC7MPB9327FT 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. 3.

Absolute Maximum Ratings (Note) Characteristics Symbol Note Rating Unit Supply voltage VCCA -0.5 to 7.0 V VCCB -0.5 to 7.0 Input voltage VIN -0.5 to 7.0 V Switch I/O voltage VS -0.5 to 7.0 V Clamp diode current IIK -50 mA Switch I/O current IS 64 mA VCC/ground current per supply pin ICCA ±25 mA ICCB ±25 Power dissipation PD (Note 1) 180 mW Storage temperature Tstg -65 to 150  Note: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. 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). Note 1: 180 mW in the range of Ta = -40 to 85. From Ta = 85 to 125  a derating factor of -3.25 mW/ shall be applied until 50 mW. ©2020 Toshiba Electronic Devices & Storage Corporation 3 2020-05-28 Rev.2.0 10.
