PCA9557  
8-bit I2C-bus and SMBus I/O port with reset  
Rev. 7 — 10 December 2013  
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.  
2. Features and benefits  
Lower voltage, higher performance migration path for the PCA9556  
8 general purpose input/output expander/collector  
Input/output configuration register  
Active HIGH polarity inversion register  
I2C-bus and SMBus interface logic  
Internal power-on reset  
Noise filter on SCL/SDA inputs  
Active LOW reset input  
3 address pins allowing up to 8 devices on the I2C-bus/SMBus  
High-impedance open-drain on IO0  
No glitch on power-up  
Power-up with all channels configured as inputs  
Low standby current  
Operating power supply voltage range of 2.3 V to 5.5 V  
5 V tolerant inputs/outputs  
0 kHz to 400 kHz clock frequency  
ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per  
JESD22-C101  
Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA  
Three packages offered: SO16, TSSOP16, HVQFN16
