Additional Infomation About Product

PCA9557 2 8-bit I C-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 2 SMBus and I C-bus applications. The PCA9557 consists of an 8-bit input port register, 2 8-bit output port register, and an I C-bus/SMBus interface. It has low current consumption and a high-impedance open-drain output pin, IO0. The system master can enable the PCA9557s 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 2 I C-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 2 I C-bus and SMBus interface logic Internal power-on reset Noise filter on SCL/SDA inputs Active LOW reset input 2 3 address pins allowing up to 8 devices on the I C-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, HVQFN16PCA9557 NXP Semiconductors 2 8-bit I C-bus and SMBus I/O port with reset 3.
