Bus Switch 1-Element CMOS 2-IN 14-Pin TSSOP Embossed T/R

The TC7MPB9327FT is 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 1.8V, 2.5V and 3.3V power supplies, whereas Vccb supports 2.5V, 3.3V and 5.0V 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 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 :TC7MPB9327FT). The 1A/2A inputs are connected to 1B1/1B2 and 2B1/2B2 outputs based on the combination of select input and output enable.The TC7MP9327FT supports power-down protection at the OE\ , OE input, with OE\ , OE being 5.5V tolerant. The channels consist of n-type MOSFETs. All the inputs provide protection against electrostatic discharge.
