Prehľad produktu

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. The system master can read from the input port or write to the output port through a single register. It has two hardware address pins, allowing sixteen of each device to be on the same I²C-bus without the need for bus buffers, so there can be supporting up to 128 I/Os.
  • 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
  • Sixteen programmable slave addresses using two address pins
  • Readable device ID
  • Software reset
  • Latch-up testing is done to JEDEC standard JESD78 which exceeds 100mA
