Texas Instruments PCA9536
The PCA9536 features 4-bit Configuration (input or output selection), Input Port, Output Port, and Polarity Inversion (active high or active low) registers. The data for each input or output is stored in the corresponding Input Port or Output Port register. If no signals are applied externally to the PCA9536, the voltage level is 1, or high, because of the internal pullup resistors.| Part No. | PCA9536 |

DESCRIPTION
This 4-bit I/O expander for the two-line bidirectional bus (I2C) is designed for 2.3-V to 5.5-V VCC operation. It provides general-purpose remote I/O expansion for most microcontroller families through the I2C interface [serial clock (SCL), serial data (SDA)].
