TC7MPB9327FK Datasheet Low Voltage / Low Power Dual Spdt Supply Bus Switch

Manufacturer: Toshiba

Overview: TC7MPB9326,9327FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MPB9326FT, TC7MPB9326FK TC7MPB9327FT, TC7MPB9327FK Low Voltage / Low Power Dual SPDT Supply Bus Switch The TC7MPB9326 and TC7MPB9327 are CMOS dual multiplexer/demultiplexer 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 A/Bn data lines and the VCCA / VCCB supplies. There is no restriction on the relative magnitude of the A and Bn voltages; both the 1A/2A and 1B1/1B2 ,2B1/2B2 data lines can be pulled up to the arbitrary power supplies. The Output Enable pin (OE) can be used to disable the device so that the bus lines are effectively isolated. This device consists of dual individual two-inputs multiplexer/demultiplexer with a common select input (S) and an output enable (OE:TC7MPB9326, OE :TC7MPB9327). The 1A/2A inputs are connected to 1B1/1B2 and 2B1/2B2 outputs based on the combination of select input and output enable. For TC7MPB9326, it has an active high Output Enable (OE) : When OE is High, the switch is on; when Low, the switch is turned off. For the TC7MPB9327, it has an active low Output Enable ( OE ) : When OE is Low, the switch is turned on; when OE is High, the switch is off. The TC7MPB9326 and TC7MPB9327 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. TC7MPB9326FT,TC7MPB9327FT TC7MPB9326FK,TC7MPB9327FK Weight TSSOP14-P-0044-0.65A VSSOP14-P-0030-0.50 : 0.06 g (typ.) : 0.02 g (typ.
