TC7MPB9326FT
Description
- Low-Voltage, Low-Power Dual SPDT Supply Bus Switch
2. General
The TC7MPB9326FT and TC7MPB9327FT 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 mon select input (S) and an output enable (OE:TC7MPB9326FT,...
