Toshiba TC7MPB93xx Dual Supply Bus Switches

Toshiba TC7MPB93xx Low Voltage/Low Power Dual Supply Bus Switches are CMOS 8-bit dual-supply bus switches that can interface two nodes at different voltage levels. These devices can be connected to two independent power supplies. VCCA supports 1.8V, 2.5V, and 3.3V power supplies, whereas VCCB supports 2.5V, 3.3V, and 5.0V power supplies. Bidirectional level-shifting of the Toshiba TC7MPB93xx is possible by simply adding external pull-up resistors between the An/Bn data lines and the VCCA/VCCB supplies. There are no restrictions on the relative magnitude of the An and Bn voltages; both the An and Bn (TC7MPB9307) or 1A, 2A, and 1B1/1B2, 2B1/2B2 (TC7MPB9326 and TC7MPB9327) data lines can be pulled up to arbitrary power supplies.
