TC7MPB9307FT CMOS Digital Integrated Circuits Silicon Monolithic TC7MPB9307FT 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. V supports 1.8 V, 2.5 V and 3.3 V CCA power supplies, whereas V supports 2.5 V, 3.3 V and 5.0 V power supplies. CCB Bidirectional level-shifting is possible by simply adding external pull-up resistors between the An/Bn data lines and the V /V supplies. There is no restriction on the relative magnitude of the An and Bn voltages both CCA CCB 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 V and V sides. CCA CCB 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. 3.
