PCA9674APW,118

PCA9674APW,118 is a remote 8bit I/O expander for Fm+ I²C-bus with interrupt. 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, 1MHz I²C-bus Fast-mode Plus (Fm+) family interface, with high speed data transfer it can support PWM dimming of LEDs, and higher I²C-bus drive 30mA for more devices can be on the bus without the need for bus buffers. Three hardware address inputs and interrupt output operating between 2.3V and 5.5V. 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. Application includes LED signs and displays, servers, key pads, industrial control, medical equipment, PLCs, cellular telephones, mobile devices, gaming machines, instrumentation and test measurement.

• I²C-bus to parallel port expander, 1MHz I²C-bus interface (Fast-mode Plus I²C-bus)
• SDA with 30mA sink capability for 4000pF buses
• 8-bit remote I/O pins that default to inputs at power-up
• Latched outputs with 25mA sink capability for directly driving LEDs
• Active LOW open-drain interrupt output
• Readable device ID (manufacturer, device type, and revision)
