PCA9672PW,118

PCA9672PW,118 is a remote 8-bit I/O expander for Fm+ I²C-bus with interrupt and reset. It provides general-purpose remote I/O expansion via the two-wire bidirectional I²C-bus (serial clock (SCL), serial data (SDA)). The device consists of eight quasi-bidirectional ports, a 1MHz 30mA drive I²C-bus interface, three hardware address inputs, and a reset input operating between 2.3V and 5.5V. 1MHz I²C-bus Fast-mode Plus (Fm+) can support PWM dimming of LEDs, and a higher I²C-bus drive of 30mA allows more devices to be on the bus without the need for bus buffers. The quasi-bidirectional port can be independently assigned as an input to monitor interrupt status or keypads, or as an output to activate indicator devices such as LEDs. The application includes LED signs and displays, servers, keypads, industrial control, medical equipment, PLCs, cellular telephones, mobile devices, gaming machines, instrumentation, and test measurement.
