DESCRIPTION
The PCA9556 is a silicon CMOS circuit which provides parallel
input/output expansion for SMBus applications. The PCA9556
consists of an 8-bit input port register, 8-bit output port register, and
an SMBus interface. It has low current consumption and a high
impedance open drain output pin, I/O0.
The SMBus system master can reset the PCA9556 in the event of a
timeout by asserting a LOW on the reset input. The SMBus system
master can also invert the PCA9556 inputs by writing to the active
HIGH polarity inversion bits. Finally, the system master can enable
the PCA9556’s I/Os as either inputs or outputs by writing to the
configuration register.
The power-on reset puts the registers in their default state and
initializes the SMBus state machine. The RESET pin causes the
same reset/initialization to occur without depowering the part.
The PCA9557 8-bit I2C SMBus I/O port with reset is the higher
performance pin-for-pin replacement for the PCA9556.
