PCA9672D,512

The PCA9672D,512 is an 8-bit remote I/O Expander for the two-wire bidirectional I²C-bus (serial clock (SCL) and serial data (SDA)). It consist of eight quasi-bidirectional ports, 1MHz 30mA drive I²C-bus interface, three hardware address inputs and a reset input operating between 2.3 and 5.5V. 1MHz I²C-bus Fast-mode Plus (Fm+) can support PWM dimming of LEDs and higher I²C-bus drive 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.

• 8-bit remote I/O pins that default to inputs at power-up
• Latched outputs with 25mA sink capability directly drive LEDs
• Total package sink capability of 200mA
• Active low reset input
• Active low open-drain interrupt output
• Readable device ID
• Software reset
• Latch-up testing is done to JEDEC standard JESD78 which exceeds 100mA
