PI4MSD5V9544A
Description
The PI4MSD5V9544A is a 1-of-4 bidirectional translating multiplexer, controlled via the I2C bus.
Key Features
- Four interrupt inputs, INT0 to INT3, one for each of the SCx/SDx downstream pairs, are provided
- One interrupt output, INT, which acts as an AND of the four interrupt inputs, is provided
- A power-on reset function puts the registers in their default state and initializes the I2C bus state machine with no channels selected
- External pull-up resistors pull the bus up to the desired voltage level for each channel
- All I/O pins are 5 V tolerant
