REMOTE 4-BIT I²C AND SMBus I/O EXPANDER

WITH CONFIGURATION REGISTERS

www.ti.com

SCPS125C–APRIL 2006–REVISED NOVEMBER 2006

The Input Port register (register 0) reflects the incoming logic levels of the pins, regardless of whether the pin is

defined as an input or an output by the Configuration register. It only acts on read operation. Writes to these

registers have no effect. The default value, X, is determined by the externally applied logic level.

Before a read operation, a write transmission is sent with the command byte to instruct the I²C device that the

Input Port register will be accessed next.

BIT

Not Used

DEFAULT

The Output Port register (register 1) shows the outgoing logic levels of the pins defined as outputs by the

Configuration register. Bit values in this register have no effect on pins defined as inputs. In turn, reads from this

BIT

Not Used

DEFAULT

The Polarity Inversion register (register 2) allows polarity inversion of pins defined as inputs by the Configuration

register. If a bit in this register is set (written with 1), the corresponding port pin's polarity is inverted. If a bit in

this register is cleared (written with a 0), the corresponding port pin's original polarity is retained.

BIT

Not Used

DEFAULT

The Configuration register (register 3) configures the directions of the I/O pins. If a bit in this register is set to 1,

the corresponding port pin is enabled as an input with high-impedance output driver. If a bit in this register is

cleared to 0, the corresponding port pin is enabled as an output.

BIT

Not Used

DEFAULT

Power-On Reset

When power (from 0 V) is applied to V_CC, an internal power-on reset holds the PCA9536 in a reset condition

until V_CChas reached V_POR. At that time, the reset condition is released and the PCA9536 registers and

I²C/SMBus state machine initialize to their default states. After that, V_CCmust be lowered to below 0.2 V and

then back up to the operating voltage for a power-reset cycle.
