TC7WPB9307FK,LF(CT

Low-Voltage, Low-Power 2-Bit Dual-Supply Bus Switch The TC7WPB9306FK and TC7WPB9307FK are CMOS 2-bit dual-supply 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 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:TC7WPB9306FK, OE:TC7WPB9307FK) input is common for all the 2-bits of the data lines; thus these device are used as a single 2-bits bus switch. For the TC7WPB9306FK, Output Enable (OE) is active-High: When OE is High, the switch is on; when Low, the switch is off. For the TC7WPB9307FK, Output Enable (OE) is active-Low: When OE is Low, the switch is on; when High, the switch is off. The TC7WPB9306FK and TC7WPB9307FK 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.
