PCA9557

8-bit I²C-bus and SMBus I/O port with reset

Rev. 06 — 11 June 2008

Product data sheet

1. General description

The PCA9557 is a silicon CMOS circuit which provides parallel input/output expansion for

SMBus and I²C-bus applications. The PCA9557 consists of an 8-bit input port register,

8-bit output port register, and an I²C-bus/SMBus interface. It has low current consumption

and a high-impedance open-drain output pin, IO0.

The system master can enable the PCA9557’s I/O as either input or output by writing to

the conﬁguration register. The system master can also invert the PCA9557 inputs by

writing to the active HIGH polarity inversion register. Finally, the system master can reset

the PCA9557 in the event of a time-out by asserting a LOW in the reset input.

The power-on reset puts the registers in their default state and initializes the

I²C-bus/SMBus state machine. The RESET pin causes the same reset/initialization to

occur without de-powering the part.

JESD22-A115 and 1000 V CDM per JESD22-C101

I Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA

I Three packages offered: SO16, TSSOP16, HVQFN16
