PCA9556 Octal SMBus Registered Interface

PCA9556 Description

INTEGRATED CIRCUITS PCA9556 Octal SMBus Registered Interface Product specification 1998 Dec 18 Philips Semiconductors Philips Semiconductors Produ.
The PCA9556 is a silicon CMOS circuit which provides parallel input/output expansion for SMBus applications.

PCA9556 Features

* SMBus compliance with fixed 3.3V voltage levels
* Operating power supply voltage range of 3.0V
* 3.6V
* Active high polarity inverter register
* Write protect register
* Active low reset pin
* Low leakage current on power-down
* Nois

PCA9556 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. T
