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.
