1. Functional Description
• Low-Voltage, Low-Power 8-Bit Dual-Supply Bus Switch
2. General
The TC7MPB9307FT is a CMOS 8-bit dual-supply bus switch that can provide an interface between two nodes
at different voltage levels.
The TC7MPB9307FT 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 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 TC7MPB9307FT 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 TC7MPB9307FT 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.

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.

Note : The operating ranges must be maintained to ensure the normal operation of the device.
Unused inputs and bus inputs must be tied to either VCCA or GND.
Note 1: The VCCA voltage must be lower than the VCCB voltage.
Note 2: Operating Ranges of Ta = -40 to 125 are only applicable for products which manufactured from April
2020 onward.
